Set in a stunning vintage inspired mount, this renaissance ring features a colour changing lab grown alexandrite stone in its centre. Handcrafted in 9ct rose gold, the decorative band holds ten round cut natural diamonds; five on either side of the gemstone, with a further two diamonds positioned inside each of the four prongs. 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. Unsurprisingly, this unique colour changing property makes alexandrite one of the rarest and most sought after gemstones on the market.Single 1.75ct lab grown alexandrite, 18 diamonds, 1-2/K-M, totalling 0.3ct.
