Finding Your Perfect Bracelet

Tennis vs. Bangle

A flexible tennis line drapes to the wrist for everyday sparkle; a rigid bangle makes a clean, sculptural statement.

Finding Your Fit

Measure your wrist and add ½–1 inch for comfort. Most styles are made to order — tell us your ideal length.

Carat & Sparkle

Total diamond weight is spread across the line — choose a delicate carat for subtlety or go bold for full brilliance.

Metal & Tone

White, yellow or rose gold, platinum or silver — pick a tone that flatters your skin and stacks with what you wear.

Buying guide

About lab-grown ruby

A lab-grown ruby is the same mineral as a natural ruby, corundum colored red by chromium, grown in a lab instead of mined. It has the same hardness, 9 on the Mohs scale, so it stands up well to daily wear on the wrist. Lab-grown rubies give a clean, even red at a price far below natural rubies of the same size. Lab-grown or natural, ruby is the birthstone for July and a traditional gift for a 40th anniversary.

How an in-line tennis bracelet is built

Every lab-grown ruby sits in its own small link, so the bracelet bends and lies flat on the wrist. Shared prongs let neighboring stones sit close together, so you see a nearly unbroken line of red with little metal between them. The total carat weight sets the stone size: 2 to 4 carats total weight gives a fine, delicate line, while 8 carats and up gives larger stones and a bolder look.

Gold color and karat

Yellow gold gives the classic warm pairing with red, rose gold softens it, and white gold makes the red look brighter and cooler. 14K gold has a richer color; 10K costs less and is very durable. The bracelet starts from about $1,600 at its smallest size.
