Fancy Color Lab-Grown Diamond Tennis Necklaces

Three fancy vivid colors, one continuous 4-prong line. Our fancy color lab-grown diamond tennis necklaces come in vivid pink, vivid yellow and vivid blue — 3mm through 6.35mm, 14.30 up to 75.00 ctw, in 16, 18, 20 and 22 inch lengths.

Yellow gold warms the color, white gold cools it. Every stone is hand-set at the owner's bench in New York's Diamond District — selected, cut, set and sold under one roof, with no wholesaler and no retail markup. Made to order and shipped fully insured.
