A lab diamond Cuban link chain is the centerpiece of an iced out look: thick, interlocking links fully set with real lab grown diamonds, finished with a box clasp built to carry the weight. Every chain here is handcrafted in 925 sterling silver or 10K, 14K or 18K white, yellow or rose gold.
Width. Around 8 to 10 mm is subtle enough for daily wear. 12 to 15 mm is the classic iced out Cuban. 18 mm and wider is a heavy statement chain that stands out on its own.
Length. 18 inches sits at the base of the neck, 20 inches at the collarbone (the most popular choice for men), 22 inches just below it, and 24 inches works best when you add a pendant such as one of our custom lab diamond pendants.
Clasp. A box clasp with a double safety latch keeps a heavy chain secure. Many iced out Cubans also carry diamonds on the clasp so the chain looks continuous.
Lab grown diamonds are real diamonds with a hardness of 10 and pass diamond testers. Moissanite (about 9.25 Mohs) looks similar with more colorful fire and a lower price; compare with our moissanite Cuban chains. For a slimmer single-row look, see our lab grown tennis chains.
Our chains are made in solid 925 sterling silver or solid gold, never plated brass. Silver pieces can be finished in white, yellow or rose tone.
If this is your first iced out chain, 10 to 12 mm at 20 inches suits most builds and pairs well with a pendant later.
Soak in warm, soapy water, brush gently with a soft toothbrush, rinse and dry. More tips are in our jewelry care guide.
