Lab-Grown Diamond Necklaces
Nothing carries a diamond like the neckline. This collection gathers all 288 of our lab grown diamond necklace designs, $268 to $25,557 — from a single diamond on a necklace chain to an unbroken strand of stones — every diamond IGI-certified and every chain solid gold.
Choose your style
A pendant puts one focal point at the centre; a tennis necklace runs stones around the entire line. In between sit stations, solitaire drops and gold pendant necklace classics in white, yellow and rose.
Layered necklaces, done right
Layering necklaces works on a simple rule: two-inch gaps. A 16-inch piece, an 18 and a 20 stack without tangling — which is why layered necklaces in mixed weights have become the default way to wear this category.
Shop with confidence
Each piece is made to order in about 2 weeks in solid 10K, 14K or 18K gold and ships free by 5-7 day express, with 30-day free returns and IGI certification on every stone.
Chains and clasps: picking a diamond necklace that lasts
The chain does the living. Cable links are the everyday workhorse — simple, repairable, appropriately strong; box chains hold pendants rock-steady with a modern gleam; rope chains twist light down their whole length and flatter bare necklines. Match gauge to load: the heavier the stone hanging from it, the thicker the chain must run, and a fine 0.8mm chain under a hefty pendant is a snapped chain waiting for a doorframe.
Clasps are the other honesty test. Lobster clasps grip hardest and suit daily wear; spring rings are fine for lighter pieces; anything carrying serious stones should close with a confident snap and no wiggle. Check where the clasp sits, too — a small counterweight or well-placed clasp keeps the piece from rotating so the diamonds face forward, not your shoulder.
Diamond necklace FAQs
What length necklace should I choose?
16 inches sits at the base of the neck, 18 just below the collarbone — the two defaults — while 20+ drops toward the chest. When in doubt, 18 flatters the widest range of necklines.
How do layered necklaces work?
Two-inch spacing is the whole trick: 16, 18 and 20-inch pieces stack cleanly. Start layering necklaces with one diamond piece as the focal point and keep the rest simple.
What is a lab grown diamond necklace?
A necklace whose stones grew in a lab — identical to mined diamonds in every physical property, IGI-certified, and priced so the centre stone can be meaningfully larger.
Pendant or tennis necklace?
A pendant concentrates everything into one stone at the centre; a tennis necklace distributes carats around the whole line. Daily wear favours the pendant; occasions favour the strand.
Can a diamond necklace be worn every day?
Yes — that is rather the point of a single diamond on a necklace: bezel and basket settings shrug off daily wear, and solid gold chains handle real life far better than plated ones.
Is a diamond necklace a good gift?
The safest fine-jewellery gift there is — no ring size to guess, no piercing required, and a gold pendant necklace flatters everyone. Anniversaries and Mother's Day lead the calendar for a reason.
