Stunning elegance. Each of these breathtaking halo drop earrings are set with a sparkling cushion-cut purple fancy lab-grown sapphire center stone surrounded by round Lassaire simulated diamonds. The earrings are in sterling silver bonded with platinum with exquisite milgrain detail. Lab-grown sapphires have the exact same chemical, mineral, and optical properties as natural sapphires which vary in color, texture and pattern. We make every effort to keep our lab-grown sapphire stone colors consistent. However, all lab-grown sapphires may not be exactly as shown on the website. Stones may appear lighter, darker or have natural variations.
