Lab Grown Diamond Tennis Necklace: Length and Carat Guide

Quick answer: The most popular length for a lab grown diamond tennis necklace in the US is 16 to 18 inches, which sits at or just below the collarbone. For carat weight, around 5 to 10 carats total gives a refined everyday look, while 15 carats and up creates a dramatic, special-occasion sparkle.

A tennis necklace is a continuous line of matched diamonds, and it frames the face like nothing else. Here is how to choose the right length, carat weight and style.

What to Check Before You Buy

• Matched stones: diamonds should be even in color and size along the whole length.
• Flexibility: the necklace should drape smoothly, without stiff sections.
• Clasp: a box clasp with a safety latch is the standard for security.
• Metal: 14K gold is a durable, popular choice for everyday wear.
• Weight: high carat necklaces can feel heavy; try to feel the weight or ask for it in grams.
