Here's a pic of the stuller settings. I don't believe they are knife edge. They come in plat. looks like the low set 4 prong one might work? Patty has one, you can pm here for more info but I personally love the look and considered using the head on my e-ring at one time.
mrssalvo is right. The Stuller Solstice comes in a knife edge or a non-knife edge which I believe they call their bombe shank. Here is a picture from BTD with two Solstices...one knife edged and one not. These are 6 prongs each but you could get 4 prongs. Also, you can choose higher or lower set heads.
I do believe that the Stuller band is more like 2.3 mms or maybe 2.6 mms.
Thanks for the advice thus far! I like the Stuller setting, but it seems like it has a lot of metal in the prongs compared to the Tiffany setting. Or am I just not remembering accurately?
I think you may have a tough time finding a stock piece with all the criteria you listed. The Tiffany Head is copyrighted and any close pieces have the knife edge too. have you considered going custom?
Yep, that''s what I was thinking mrssalvo. I really like the original Tiffany setting, but it''s a little thick for my tastes. I guess I''ll contact WF to see if they can modify their knife-edge setting a bit.
Call GOG, I tried on a ring that matches that description exactly in their store last Tuesday. I dont know if this would help but it was about 400$ (I think) for the plat and was the second one from the box of solitaires I tried on.
Stuller makes a variety of tiffany styles, I believe what you want are called the "comfort tiffanies." The prongs are thin (less metal than the solstice) but the prongs are not just like the orig Tiffany setting however (not split). Most any store will have their catalogue and you can view solitaires til your head explodes!
You should try to view them in person if possible. I didn;t like the solstice at all in the pictures, but loved it in person. It has a certain uniqueness and grace that isn''t captured in the photos. I particularly liked it in 4 prong. It was a close runner up to my vatche x prong (and would have been half the price too).
Also check the solitiare selection on whiteflash - they have several that may be what you are looking for.
With the variety of simple solitaires out there, I doubt you''ll need to go custom to find what you want.
Good luck, let us know what you choose.
