Hello, ladies (and gents?)! I've been DESPERATELY searching for a source on this. I have dreamed of having a truly GIANT cocktail ring made for some time now, and cannot seem to find a stone large enough. I want basically something that looks like the cocktail rings Marc Jacobs designed for Louis Vuitton two years ago. I have found jewelers who say that they can certainly set a stone of the size I want, but nobody seems to have a source for stones large enough. I'm looking for a rock in the 80-150 carat range, emerald cut, in a swiss-blue topaz / aquamarine color. The stone should measure between 35-50 mm by 20-30 mm. It could be CZ or real, doesn't matter to me, but since I don't want to pay more than a couple hundred for the stone, I know I'm pretty much just in CZ territory. I would think that it would be easier to find stones this big of this size, but still no luck. eBay seems to have tons of giant CZs, but they are never emerald cut and NEVER blue! If I could even find a stone the right COLOR, I could always take it to a jeweler and have them cut it down to the right shape. Anyone have any hot tips? Thanks a million!
