18K Lab Grown Diamond Necklace – 2 Carat Round Diamonds, Hallmarked

Set with 49 round brilliant diamonds for a striking total of 2.02 carats, this 18K lab grown diamond necklace is a genuine statement piece built for weddings, receptions, and milestone gifting. The diamonds are arranged to maximise visible spread across the neckline, so the full carat weight reads clearly rather than disappearing into a small cluster.

What is Total Carat Weight (TCW)?

Total carat weight refers to the combined weight of every diamond in a piece rather than a single centre stone — here, 49 round brilliant diamonds add up to 2.02 carats. This construction spreads sparkle across a wider visible area than one large stone would, which is why multi-stone necklaces like this one often look more substantial in person than the carat number alone suggests. Each diamond carries the same IGI-certified 4Cs grading as a solitaire.

Metal & Karat Options

This piece is available in 18K gold, so you can choose the purity that best fits your budget and how often you'll wear it — 18K gold offers everyday durability at a friendly price point, while 18K gold gives a richer tone, higher gold content, and stronger resale value. Each karat option comes in your choice of Yellow Gold, Rose Gold, or White Gold, letting you match the finish to your existing jewellery or personal preference.

Caring for Your Diamond Necklace

To keep this piece looking its best, clean it gently with a mixture of mild soap and lukewarm water using a soft-bristled brush, then pat it dry with a lint-free cloth. Store it separately in the pouch or box provided to prevent it from tangling with or scratching other jewellery. Avoid direct contact with chlorine, perfume, lotion, and hairspray, as these can dull the metal's shine and affect the diamonds' sparkle over time. We recommend having the setting professionally checked once a year to make sure every diamond stays secure.
