Please set it in prongs, not bezel or gypsy set unless your bench is extremely skilled with setting softer coloured stones. Other than that, I'd love to see your ring plans for the tourmaline!
Ah really? I'll look up some styles but usually see men's set in semi or full bezel. I think my biggest concern here is the length/size of the stone. Wanting a stone and then figuring out how the realities of setting are two different beasts.
Sweet stone! From the images, I thought it would have a greater ratio than 11x9.
Are you going to set it vertically or horizontally? I would do a signet style ring, horizontally, with a very light texture on the ring and a smooth, polished bezel.
The picture shows a true tension setting (no support structure underneath or around it). I would be extremely cautious as to selecting who is to create this setting or risk the stone falling out.
Being it's a lighter stone I was thinking a clean, modern look would be good. I do appreciate any input; obviously I wouldn't want the stone to pop out. Since it isn't an emerald cut would it be more secure in the true tension setting?
A tourmaline is not really the best candidate for tension setting. You can get a very similar look with faux tension setting (with a hidden bridge under the stone for structural integrity) without the risks. You will lose the open profile of the stone but it will be safer, both during setting and everyday wear.
