Hello all! I'm looking for a 3 stone engagement ring with a red or blue CS center and diamond side stones on behalf of a friend. Ideally white metal, ideally 6 prong settings with roughly similarly sized stones rather than more traditional proportions. I suspect center stone would need to be sapphire or spinel for durability, med dark stones are ok, and budget is around $3500 USD. Given the budget, I suspect we're looking for a complete ring through LT or similar.......... Any ideas would be much appreciated!
