A statement of elegance. This adjustable halo necklace features a pear-shaped padparadscha fancy lab-grown sapphire and Lafonn's signature Lassaire simulated diamonds. The necklace is set 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.
