Timeless classics for everyday wear. This classic alternating tennis bracelet is set with Lafonn's signature Lassaire simulated diamonds and fancy lab-grown rubies in sterling silver bonded with platinum. Lab-grown rubies have the exact same chemical, mineral, and optical properties as natural rubies which vary in color, texture and pattern. We make every effort to keep our lab-grown ruby stone colors consistent. However, all lab-grown rubies may not be exactly as shown on the website. Stones may appear lighter, darker or have natural variations.
