Oh, great EmpegBBS oracle, holder of all knowledge and wisdom...
Anyone out there a metallurgist/jeweller? I'm in the process of shopping for a wedding band (for myself -- my fiancee's has already been purchased), and haven't exactly been stunned by the offerings I've seen in the stores. I currently wear a white-gold ring, and it's too soft of a metal -- I've had to get it re-rounded more than once.
On a side note, for those of you who are woodworkers (hi Mark!), do you know of any hardwoods out there that might be suitable for a wedding band that would (pardon the pun) be subject to substantial abuse, including frequent and prolonged immersion in water? I've seen some rings that, I think, are wood inlays on a metal band, but they've come with warnings about repeatedly getting them wet.
Cheers,

Well, the traditional harder-than-gold precious metal would be platinum. I seem to recall seeing some titanium rings, but titanium isn't really all that hard, though far harder than gold, silver, or platinum. But you could be Mr. Cool and get someone to construct you an iridium ring or something. Huh. Actually, it looks like many platinum rings are alloyed with iridium or ruthenium. Check those out. Here's some relevant information.

I spent five years in a retail jewelry store. Not exactly sure what your question is about the gold wedding band... you're saying you've got an existing white gold ring that isn't very durable and your'e looking for something better?
I was personally satisfied with an ordinary 14k gold wedding band. If it's beefy enough, it'll stand up to some punishment. If it occasionally gets bonked out of round, them's the facts of life, live with it, and take it back to the jeweler where you bought the ring and they'll be happy to pound it back into shape and polish it up real nice for you. Anything to get you back in the store so they can show you more pretty shiny things to buy.
I certainly wouldn't go with wood. That's going to be a lot less durable than even very soft gold.

I wear a titanium wedding band and I love it. They're comfortable, not real expensive, weigh about the same as aluminum, and are really tough. On the other hand, you'll never win a "bling" competition with one.
Make sure to get the right size! I was told when I bought it that you can't get it resized at a normal jeweler because the metal has be heated much hotter more than gold or silver and they don't have the equipment to do it.
According to wikipedia "It is a light, strong, lustrous, corrosion-resistant (including resistance to sea water and chlorine) metal....The two most useful properties of the metal form are corrosion resistance, and the highest strength-to-weight ratio of any metal. In its unalloyed condition, titanium is as strong as steel, but 45% lighter."

Another suggestion: My wedding band is a somewhat rustic celtic knot band. I'm sure it's dinged all to hell, but you can't tell, because that's the way it's supposed to look. Also, on the few occasions it's gotten out of round, I've just reshaped it a little by putting it in the hinge side of a door jamb and pulled the door to. Worked like a charm.

Yup. That's the gist of it.

It's the "some" I'm concerned about. I've subjected my ring to far more than "some" punishment. The last time it was re-rounded, it only stayed round for about a month, before I squished it again. The alloy is too soft for the size of the ring, and the abuse that I give it. I don't want to go with a huge ring, just so that it'll be beefy enough to not get squished. For one, I don't like the look of large rings, and for two, I'd just rather have a metal that's not so soft in the first place, so I don't have to worry about whether it's beefy enough to withstand a bit of punishment.
Cheers,

I seem to remember being told that Platinum isn't all that shiny, and that jewelry made from it is plated with something else that can be polished to a shine.

I do like the look of some of the celtic knot bands. I'll take another look at them.

I'll have to give that a try...
Thanks for your congratulations, and the link, above... I wasn't aware that making a metal harder doesn't necessarily mean that it's abrasion resistant, as well.

I've looked at titanium before, and it's still a good option. I'm not particularly looking to win a bling competition, so that's not really something I'm worried about.

I'm honestly not sure. Once I hooked it on something, in which case it's malleability was actually a good thing, because the bending ring saved my finger from worse injury. I somehow squished it while mountain biking, a few times, though I'm not sure how -- crashing into a tree, maybe, or perhaps just the deathgrip on the handlebars. I've accidentally stuck it between a rock and a kayak (or, more frequently, the paddle) multiple times. Bloody knuckles are not uncommon for me.

It has been a long, long time, but I remember a groundskeeper at a hotel cum golf course in New Hampshire who lost his ring finger to a tool that got jammed (in a lathe? a grinder?). Anyhow, having the ring be the weaker link has something to recommend it.
Semi-romantic non sequitur. I know this guy who bought wedding rings at a stall in Suez. Many years later it became obvious -- a paradox -- that they had too much gold (24K?). They were too soft, so started to break up and wound up in a jewelry box. So the crafty fox snuck them out of the house and had them rebuilt on a sturdier (14K?) ring just in time for his 40th anniversary. A big hit, that was..

Apparently, you can get Tungsten Carbide or Palladium rings these days, too.

Mine is a reasonably strong gold celtic band (I went for 9 carat as it is a bit tougher than 14) - but I remove it when climbing, lifting weights or karting just from a safety aspect. I really don't want any metal to embed itself in my fingers. I'll have to post a pic later on - celtic bands are always nice (I've worn one for 17 years now, a silver one for 9 years, then I replaced it with a gold one once I got married) as they don't show up scratches, scuffs or dings as much as a plain band.

I hear you on the weight thing: the boy Fiennes's wedding-ring is titanium, and, while it certainly looks the part, when he handed it to me so I could feel the weight, I suddenly stopped thinking "wedding-ring" and started thinking "ring-pull". So if people do go for titanium ones, I recommend adopting the whole "No, nasssty hobbitses can't hold it, mine! my own!" sort of attitude.

On that note, I wanted the "one ring to rule them..." runes engraved inside my ring, but the wife vetoed that, and we opted for initials and the wedding date instead

I don't like the look of yellow gold on my hands, either. I do like the look of some of those tungsten rings, but it looks like it might be difficult metal to set stones in -- SWMBO's engagement ring has channel set sapphires beside the diamond, and it would be nice to have some sort of matching theme on my band.

Some cool concepts, there. I couldn't do the carbon fibre... it screams "ricer" or "weight weenie cyclist". If I were a civil engineer, I'd go with the steel-and-concrete for sure, but I'm most drawn to the enamel ones, right now. Thanks for pointing out that site!

Since my girlfriend doesn't read these forums and I doubt any of her friends will catch my posts in Google, can we expand this thread to engagement rings? I've already got one long-time favorite jewelry store to consult with first for the setting, but just in case they no longer offer the typees of rings I have in mind, I'm curious what tips you guys have. I'll be purchasing the rock elsewhere and having the (or "a") shop set it. Whatever it ends up being made of - I hate the idea of a diamond, but I suppose I will end up with one anyway. The place I'm already planning to check makes all their own stuff by hand. They used to make a really cool ring that looked like it held the stone by horizontal clamping force only - and it didn't protrude from the top very much at all. I hate rings where the stone sticks out like a weapon. My soon-to-be fiance gets no voice in deciding what the ring will be like. That would just be against everything I stand for. I suggest any guys who go shopping for this stuff with their future wives should instead go looking for a pair of balls.  Or if style isn't your bag (no pun intended) then consult someone else. Judging by the excellent ring recommendations in this thread already I don't think anyone here has these issues. Does the diamond industry still advocate spending 2 months salary on an engagement ring? Ummmm. I don't think that's going to happen. You can't put a price on our love, but I'd probably have a heart attack spending that much on a tiny piece of jewelry. I know she'd rather have money spent on other things like travel anyway.

This is called a "tension mount" or "tension set".
Tension Ring, with some links.

The type you're thinking of is tension set, which really does make a neat ring. For anyone who hasn't seen one, you basically take a very strong ring, slice it, pry it open, and insert the gemstone in, and let the ring snap back to hold the stone. It only works with hard stones that it won't crush. It's supposed to be good for active people, as the stone is held by a lot more force than the little bended prongs in a traditional mount.

I don't have a problem with the ring aspect. The concept of the diamond was introduced by the diamond industry, but not the ring itself. A jewelry-based offering has been around since classical times. I know this much from school. Wikipedia seems to agree Thanks for the link. I'll check it out and make sure not to leave any browser history...

That's okay with me! And congrats.

You should call ahead, and find out if they'll change a setting fee. I think I got stuck with a $65 charge for doing it this way.

I'm not too happy with the idea of diamonds, either. I ended up buying a certified Canadian diamond, since it's the closest thing to a guarantee you can get that a) it's conflict free, b) not part of the DeBeer's cartel, and c) stands a glimmer of a chance that the mine is being operated in a semi-ecological manner. (Plus, a Canadian diamond seemed apropos, given the circumstances.)
Take her to see Blood Diamond, and see how much she still wants a diamond, after that. It's a fictionalized account, but it's based very heavily on reality.
I ended up buying my diamond online. They also do custom designed rings, if you can't get the setting you want at your local store.

A tension setting... they're still pretty common in all the jewelry stores I was in, so I doubt you'll have any trouble finding one. There are examples present on most of the websites linked above.
Quote:

Ditto, and they can be a pain for other reasons, too -- like wearing rubber gloves for gardening, washing dishes (SWMBO's example, not mine!), or getting your hand through a rubber gasket on a dry-top.

Heh. We went window shopping, to find out the range of styles that she liked. I'd rather be accused of needing to find a pair of balls, than spend $$$ on something that she truthfully hates. Once I knew what sort of styles she liked (and thankfully, they lined up with mine), I did everything else without her input, and she had no knowledge of when the ring showed up, or when the proposal would be.
Quote:

Yeah, it's pretty ridiculous. FWIW, though, I don't know anyone that's done that. In fact, I think I actually ended up spending less than a single paycheck. But you can get some pretty ugly looking stones for some hugely inflated prices, if you go down to your local mall. I recall seeing one 2 carat stone/ring pricetagged at $18k, and you could see the inclusions in the diamond with the ring sitting in the display case. :-p
The also still push the idea that buying a diamond is an investment, and that the value of a diamond will go up. Total BS, of course -- diamonds are so plentiful that, unless it's some rare colour or size, there's no "used" market for them at all. The money you put into a diamond is gone for eternity.
If you want to keep the cost down, look for an underweight stone. Once you hit the magic weights (1/2 carat, 3/4 carat, 9/10 carat, and 1 carat), prices can nearly double, yet the stone size doesn't change appreciably. The difference between a .5 carat round diamond, and a .45 carat round can't really be detected -- it's less than a millimeter change in diameter.
The best website I found online for understanding diamonds was undoubtedly PriceScope. When looking at the diamonds from the online site, I compared the prices against comparable diamonds listed on PriceScope. If they were too far out of whack, I knew I was getting ripped off -- I rejected a couple of stones that way. I also rejected a couple of stones based on the emailed certs, and plugging the numbers into the Holloway Cut Advisor.

Congrats, Bruno! It sounds like you an I have similar taste in rings. My fiancee made it fairly clear that, if I were to ever get her a ring, she wasn't the type who wanted to go shopping with me. She wanted to be surprised. I was lucky that I picked a design she absolutely loved. I was pretty proud of it, too. I had gone to a store and not liked any of the settings. Then he showed me a pink piece of plastic that represented a ring he was designing at the moment. I could tell that it was exactly what I wanted, and due to my fiancee's distinctive name, he decided to name it after her if I bought it. Here is the Arista:  It's actually hard to tell, but the setting suspends the stone nicely.

I'm no jeweler or metallurgist, but I am a mechanical engineer that specialized in strength analysis.
If you want it to be tough, then get a stainless steel or tungsten carbide ring. They offer two different kinds of "toughness" and it depends on the kind of "abuse" you give it.
Tungsten carbide is very *hard*, meaning it can only be scratched by diamond or corundum. If your rings get abraded, scuffed or otherwise scratched up, and you don't like that, then TC is a good choice. It also has a kind of cool appearance.
If your rings get crushed or bent, then you probably want stainless steel, which is about twice as resistant to bending as tungsten carbide.
Everyone thinks that titanium is a super-strong miracle metal. The truth is that it is merely strong for its weight. Steel is considerably stronger. Titanium is also reactive in acids, but stainless steel, gold and platinum are not. Non-reactivity is quite important in jewelry metal.
My recommendation is far and away stainless steel. Rather than having it made by a jeweler (who make rings by lost-wax casting), have it made in a machine shop. There is no reason to cast stainless steel as it is very easily machined, and casting it will anneal any heat treatment hardening that has been applied to the stock.
If you can get your hands on a lathe, you could make it yourself, which you might really enjoy. The stock should cost you less than a buck or two, and an experienced machinist could make you one very quickly.
All that said, realize that you should never wear rings around machinery that can damage them, as that means that the ring could also cost you your finger.

I think stainless steel would be very nice if the cost of the ring isn't important. I imagine any small engineering shop would love to make a ring for somebody.
I was going to say that it could be remade if lost, but I suspect a ring quickly gains sentimental value that outweighs any financial value.

Another mechanical engineer chiming in here: tungsten also has an incredible weighty feel, given its very high density, which is nearly as high as gold. A few density numbers: Gold: 19300 kg/m^3 Tungsten: 19250 kg/m^3 Lead: 11340 kg/m^3 Steel: 7900 kg/m^3 Titanium: 4510 kg/m^3 Magnesium: 1170 kg/m^3 A more complete list is here.-Zeke

And Platinum is denser than any of those at 21450 kg/m^3.

And that's topped by Iridium at 22650 kg/m^3.  -Zeke Teasing aside, the main point is that a steel ring would be half as hefty as some other metals (design notwithstanding), which might not be a desired feel.

My only experience with platinum is with bullion coins, but I'd have to agree with you there.

Another option to the tension set/mount is a bezel set/mount. It encircles the stone's periphery instead of using prongs/points. It prevents the stone from catching on things, and is more secure than mounting points, which can fail over time and lead to the zero-fun game of 'find the diamond'.

I'd select platinum for that reason (out of a list of precious metals).
I would like to be reminded every minute of how serious I am about such a commitment.

My fiancee's ring looks similar to that. I had 4 deep blue, square sapphires channel set on each side of the diamond, though. It gives the ring a bit of colour, and makes the diamond "pop" a bit more, seeming a little bigger than it really is. On Sunday, a clerk at the mall complimented SWMBO on the ring... The wedding band has matching sapphires channel set around the top.

I can use some google/ebay help... To get the really nice tension settings I'd like, it looks as if I'll probably have to order from the US. On top of that, because a tension setting cannot be resized by cutting, I will require very exact ring size... At this point I'm thinking of using a temporary ring for the proposal and then getting a measurement for the final ring which would be here about a month later. I can have the real diamond in my hands at the time of proposal though. So I'm looking for a cheap ring that doesn't look like it was designed for a gypsy, a whore, or an 80 year old. Nor something that just looks like it's more expensive than the real ring to come. On ebay most of the fake stone rings include a monster rock designed for tacky show. I'm looking for a rather simply ring with a 0.5 to 0.75ct "sized" stone (cubic zirconia, plain glass whatever). Here are some of the settings I'm trying to decide on for the final ring: http://www.sndgems.com/platinumgoldtensionsetrings2a.htmhttp://www.sndgems.com/gelin-abaci-tension-ring.htm (with square or round cut stone) http://www.sndgems.com/platinumgoldtensionsetrings4a.htmhttp://www.sndgems.com/TR054gelinabaci.htmIf I was buying the setting locally, many jewelry stores would let me borrow a ring, but I don't have this luxury. I'd really like to get a GelinAbaci setting. There are many more styles on the GelinAbaci corporate site that I also like. Obviously in a cheap ring I'm not looking for a tension setting. Something using standard prongs but as low profile as possible would be ideal. I've been unsuccessfully combing eBay and am about to start on Google...

My mother used to buy what you're looking for from QVC. They had, what were they called?, CZ stones in gold rings for $50-$75. Looked exactly like the real deal. Since its just an ornament, its just as good as the real deal, IMHO, but that's another issue. Ah yes, they were called " Diamondique". This should be exactly what you want for your temporary ring. They have the ridiculous guady sizes, but also some that look like real diamond rings that an ordinary human would buy. Reputable company, extremely low prices due to very high volume. Jim

Going to dig up this old thread.... Dig dig dig... I did end up getting a very nice Gelin Abaci tension ring for my fiancée, model TR-005 in 18K white gold. I sent the jeweler (not the one in the link) a Canadian diamond for mounting and the whole thing looks stunning. The wedding is coming up on April 24th in Lagos, Portugal and we're looking at wedding bands now. At least starting to look. Just looking through the links for all the non-previous metal rings that were posted earlier. Has anyone come upon any other interesting designs? She'll likely get something made of gold, but I'd like to get something that looks nice but is more resilient and lesser cost (rather spend the extra cash on our new home right now to tell you the truth).

I recently read about Pat Pruitt and his interesting mixture of industrial and Native American design.

...ok, I admit it I don't have a DU wedding ring, its just Platinum. Actually, if you check the chart -- you both win! Gold and Tungsten are denser than Uranium. And Platinum even beats Plutonium. I'll admit I was quite surprised when I first found out that gold was heavier than uranium.

Ok, I decided what ring I'd get for myself, bought it two weeks ago and it just arrived today. I bought this tungsten ring: http://www.escapesdesign.com/rings/tungsten/ctungsten_ring_007.htmlIt's just as nice in person as it looks in the photo. Very nice weight to it as well. Now time for my disappointment. The company, Escapes Design is located in Quebec and bills themselves as designers of jewelry, both in title and in their company bio. I was under the impression these rings were designed and made by them, here in Canada. The FedEx shipment was drop-shipped from Hong Kong. The ring is made by a company called "coi" - doing an internet search brings up a number of other retailers selling the same ring for $99. I paid $225. I'm a little ticked off because if the ring had been advertised as a "coi" design I would have found the other retailers and have been able to make a more informed decision. I have no problem with retailers setting their own prices, but I can't help feel I was a little burned here.
