Does Metal Matter for Stone Type?

First, please forgive such a fundamental question which has probably been asked and answered many times over here (only I don't remember seeing an answer).

I have three round green garnets that I am looking to set in rings. For these stones, I am drawn to art deco type settings like this: http://www.ebay.com/itm/Vintage-Antique-Certified-1ct-Diamond-Platinum-Art-Deco-Engagement-Ring-/201212221890?pt=LH_DefaultDomain_0&hash=item2ed92ed9c2

My question is can I set grossular and demantoid garnets in platinum? Is there any rule of thumb with respect to a gem's hardness and type of metal to be used? I've been looking at antique settings on ebay and thinking that I could buy one and replace the diamond with one of the garnets. I am a total amateur when it comes to setting stones. Anything I need to know about?

Unless you have a very good jeweler who understands the nuances of any gem softer than a sapphire, I would be careful mounting them in platinum. However, it really comes down to your jeweler. A bad jeweler can ruin a gem in 18K gold (softer metal) as well.

Hope that helps :-)

I'm still searching around for a good jeweler close to me who does not cost an arm and a leg, so you're advice is well received. Thanks.
 
Agreed with the above. It really comes down to the jeweller. My engagement ring is a tourmaline (!) which is bezelled (!!) in platinum (!!!), which on paper breaks all the rules about how you should handle a soft stone. I had a very skilled jeweller however, and he set it perfectly undamaged.

My sister-in-law, on the other hand, had a diamond damaged by another jeweller when she had it put in a claw setting. In theory it should have been fine, but she's now going through a lengthy process of trying to get the jeweller to admit culpability and fix the situation.
 
Hi,

What about that Joe Escabar that Gypsy talks about. I don't know how far he is from you, but maybe if you try a search here for Joe Escabar, it might turn up.

I think I'd rather have a softer stone in plat for added stability (ex. demantoid). But I second the comment re. finding a skilled jeweler.
 
Thank you all so much for your help.

amyek: I appreciate this, as I was thinking just the opposite; that a softer stone might get hurt by such a hard metal as platinum. :confused:
 
Slightly exaggerated here, but just for example I would not try to set a sphene in a platinum bezel. The forces required to push the metal over the stone would be far too much for the stone to bear. Even in prongs I would only trust someone who was the Yoda of settings.

I would also be really careful with fracture filled stones too, like emerald, and platinum.
 
I guess that means that spinel with platinum is starting to get risky?
 
So given that the stones to be set are grossular garnet and demantoid garnet, what would you all recommend with respect to metal type?
 
Just wanted to say thank you for asking this question as I'm going to (hopefully) start researching a similar thing soon. :)
 
Minou,
It's all about the skill of the jeweller. The safest is prong set because it is easier for a less experienced bench since less force/pressure required and there is more wiggle room. The only demantoid I've seen bezeled or gypsy set are in high karat gold because it is a softer and more malleable metal. If you want platinum, I'd probably stick with prong set which I've done so for mine.
