A tennis bracelet is a continuous line of matched diamonds along 18K gold links, held by a double-lock box clasp. In lab-grown, the same 5 tcw design costs about a quarter of the natural equivalent.
Who it works for
Daily wear from 3 tcw to 10 tcw. Wears with a t-shirt or a black-tie dress.
Sizing
6.5 inches is petite, 7 inches is standard (the default), 7.5 inches is larger, 8 inches is oversized. Measure the widest point of the wrist and add half an inch for comfort. Every Riyanika bracelet can be custom-sized to the nearest eighth of an inch.
Clasps and security
Box clasps with a figure-eight safety catch are the Riyanika standard for tennis and station designs. Bangles and cuffs use a concealed hinge or open-ended design. Lab-grown diamonds are chemically identical to mined diamonds and cost roughly 40–60% less, so every carat weight becomes more accessible.
