Lab-Grown Diamond Tennis Necklaces – Sleek. Seamless. Stunning.

Tennis necklaces are the ultimate statement of elegance and simplicity, lined with radiant, lab-grown diamonds that offer the same brilliance and structure as mined stones, without the ethical cost. At Karaters, our tennis necklaces are designed for clean symmetry, everyday versatility, and undeniable shine without the environmental impact.

All our lab-made tennis necklaces are handcrafted in Los Angeles's Historic Jewelry District, and a GIA Certified Gemologist grades all Diamonds. Every tennis necklace in our collection is set to make a luxury mark in your jewelry collection.
