[help] need a custom cut stone

Ineed a stone the approximate color of peridot,that can take the
heat of a near by weld and can also be channel set. It needs to
be 6x4 fairly shallow to set next to a princess cut diamond.
Hoping to find something in a synthetic corrundum,or a CZ. I
would be willing to have it cut special. ANY IDEAS…THANKS

Dear Charles, How about a Montana sapphire, I have a large
assortment and can usually come up with the desired color and
size. A natural sapphire will do all that you desire and the
cost is about the same as synthetic. Let me know what size and
shape you need.
