The beautifully designed allure ring features two round brilliant cut diamonds that elegantly sit on either side of a superior lab grown alexandrite. Precision cut into an oval shape, the stone is almost internally flawless and boasts terrific colour changing qualities. Take a look at alexandrite in natural light and you'll see intense flashes of emerald green mixed with hints of blue. Observe alexandrite in incandescent light and the stone will change to a deep purple. Slight detail on the solid 18ct rose gold band shoulders doesn't detract attention from the alexandrite but offers subtle design and balance. Unsurprisingly this is one of the most popular rings of the QP collection.Single 0.55ct lab grown alexandrite. Two diamonds 1-3/K-M, totalling 0.02ct. Oval cut.
