Men’s diamond necklaces include classic tennis necklaces and heavier Miami Cuban chains, with different diamond shapes, carat weights and lengths to choose from. Browse lab grown diamond tennis necklaces in 14K white, yellow and rose gold, along with stainless steel Miami Cuban necklaces set with lab grown diamonds.

Choosing a men’s diamond necklace

Diamond weights range from 9.5 to 41 carats total weight across the collection. Several tennis necklace designs are available in multiple carat weights, allowing you to compare different diamond sizes within the same style.

Length and width are important when choosing a necklace. Tennis necklaces range from 18 to 22.6 inches, depending on the design and carat weight. Shorter necklaces sit higher around the neck, while longer lengths fall lower on the chest. Consider how you plan to wear the necklace, including whether it will sit above or over clothing.

Diamond shape also changes the appearance. Round diamonds create the traditional continuous tennis necklace line, while emerald cut diamonds offer a more geometric look with long, rectangular facets. Both styles are available in different carat weights.

For a heavier link design, the stainless steel Miami Cuban necklaces offer two options: an 18-carat diamond necklace measuring 8mm wide and a 35-carat diamond necklace measuring 15mm wide. Both are 22 inches long and feature lab grown diamonds set across the links rather than a traditional tennis necklace arrangement.

Metal options, diamond color, clarity, certification and clasp details vary by design. Check each product page for the exact specifications and available options before choosing.
