All auctions / Jewellery & Gems / Trilogy Ring in White Gold, Tanzanite, and Diamonds


Trilogy ring in white gold, featuring a center stone of a natural 11.92-carat Tanzanite, cut in a modified stepped octagon shape. Its particularly intense hue, ranging from deep blue to violet, is classified by the ALGT laboratory as “Vivid/Deep Violetish Blue” and “Extra Fine Color Quality.” The Tanzanite is flanked by two square Emerald cut diamonds weighing 1.09 carats each, for a total of 2.18 carats. Both are GIA-certified and feature a beautiful F color: one has a clarity of VVS1, the other VVS2. Their whiteness and brilliance elegantly highlight the intensity of the purplish-blue hue of the central Tanzanite.
