Tourmalated Quartz and Black & White Diamond Gold Ring
This stunning Art Deco/Gothic statement ring is crafted in Gold (9k or 18k). The monochrome architectural design features a 12mm faceted marquise Tourmalated (Black Rutile) Quartz central stone flanked by one Black and one White Diamond set into the ring band.  
Ring shown is UK size L1/2 (US 5 7/8) but I can make similar to any size (the precise pattern of the central stone will vary as each is unique).
The band is 3mm wide and 2mm thick. It weighs xg and is fully hallmarked by the London Assay Office including my own makers mark.
(Please note that this ring is all in solid gold except for the seat on which the central stone sits, which is sterling silver to preserve the black & white nature of the stone itself)
