Who a tennis necklace works for
Occasion pieces, milestone anniversaries, and the single most-gifted generational heirloom in the category.
What to look for
18K solid gold chain and pendant (not plated, not gold-filled), a secure clasp (our default is a spring-ring for chains under 18 inches and a lobster clasp for longer), and. For diamond pendants above 0.30 ct. A GIA grading report. Lab-grown diamonds are chemically identical to mined diamonds and cost roughly 40–60% less, so every carat weight becomes more accessible.
Chain length
16 inches sits at the base of the neck (choker). 18 inches. Our default. Sits just below the collarbone and works with most necklines. 20–22 inches drops lower and layers cleanly with a shorter chain. Every necklace ships with an adjustable chain unless stated.
