Kay Lab-Grown Diamond Solitaire Studs vs Houston Diamond District Radiant Lab Diamond Studs

Buy the Houston Diamond District pair if you want the better-made earring: 14K gold instead of 10K, a higher color grade (E/F versus unstated white), and IGI certification on the stones. Buy the Kay pair if you prefer a classic round brilliant look and a mainstream jeweler with easy in-store service. Both hold 1/2 carat total, so the choice comes down to metal purity, certification and cut shape, not size.

• Choose the Kay studs if you want the traditional round brilliant sparkle and the backing of a large chain jeweler for service and returns.
• Choose the Houston Diamond District studs if you want 14K gold, IGI-certified stones and a stated E/F color grade.
