Lab-Grown Diamond Necklaces
From a single floating diamond to full tennis necklaces, each piece is set with IGI-certified lab-grown stones in 14K gold. Wear it every day or save it for the moment that matters — and pair it with one of our Italian chains for a look that's all yours.
FAQs About Lab-Grown Diamond Necklaces
Lab-grown diamonds skip the mining supply chain. They are grown in controlled facilities using CVD or HPHT processes. The stone is identical to a mined diamond. The savings come from removing extraction, transport, and commodity pricing. Most lab-grown necklaces at Silvadi run 50 to 70 percent below mined-diamond equivalents.
A synthetic diamond is a real diamond grown in a lab, with the same carbon structure, hardness, and IGI or GIA grading as a mined stone. A simulated diamond, like cubic zirconia or moissanite, looks similar but is a completely different material that wears and scratches differently over time. Everything in this collection is a lab-grown diamond. Nothing is simulated.
Lab-grown diamonds rate 10 on the Mohs scale, the same as mined diamonds. For daily wear, the setting matters more than the stone. Bezel settings fully encase the diamond and resist catching on fabric better than open prong settings. If you wear your necklace constantly or work with your hands, ask about bezel options when you come in.
Yes. Bridal shoppers wanting a coordinated necklace, earring, and ring combination can ask about pendant sets. Matching metals and stone grades across pieces is available, and IGI or GIA certification documentation is included.
The Cuban-link with bezel-set diamonds holds up best. The bezel protects the stone from impact, and the heavier chain resists daily activity better than fine-link chains. For something lighter, a single-diamond pendant on a box chain transitions between casual and formal without standing out for the wrong reasons in either setting.
Yes, and it’s one of the most common combinations in the store. A tennis necklace at 16 inches above an 18-inch solitaire pendant works because the two are visually distinct and do not compete. Keep the tennis necklace shorter so it sits clearly at the collarbone with the pendant hanging below. When both sit at the same length, they tangle and blur together.
Warm water and a small amount of mild dish soap. Let the necklace soak for 10 to 15 minutes, then use a soft toothbrush to clean around the setting. Rinse thoroughly and dry with a lint-free cloth. Skip ultrasonic cleaners on prong-set pieces, as the vibration can gradually loosen prong tips with repeated use.
