Fun and playful. This dainty adjustable three-stone necklace features a fancy lab-grown blue sapphire as the center stone with two Lafonn's signature Lassaire simulated diamonds. The necklace is in sterling silver bonded with platinum. 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.
