The marquise is one of the most distinctive cuts in fine jewelry: a long, pointed silhouette that maximizes face-up size and elongates the finger. At 3.00 Ct with E Color and VS1 Clarity, this solitaire is as clean and bright as diamonds come. IGI certified, laser-inscribed, and handset in our New York City studio in the Diamond District.
Lab grown diamonds are real diamonds, not simulants, not cubic zirconia. Grown using the same conditions that produce mined diamonds, certified to the same standards, and sold direct from the maker so you get significantly more stone for your investment.
A strong choice for an engagement ring or a stand-alone statement piece built to last generations.

Every Zack & Elle diamond is grown in a controlled environment in months rather than mined over millennia — but chemically, optically, and physically, it is identical to an earth-mined diamond. Each stone over 1ct is independently certified by IGI and laser-inscribed for verification.
Complimentary fully-insured FedEx shipping on every order, signature required on delivery. 30-day risk-free returns — full refund, no questions asked.
Yes. A lab-grown diamond is chemically, physically, and optically identical to a mined diamond — the same material, simply grown above ground instead of mined. It tests as a diamond on any standard diamond tester.
Because the diamond is grown in weeks rather than mined over millennia, and we sell direct, you get the same beauty, certification, and durability for a fraction of the price of a comparable mined diamond.
Clean gently with warm water, a drop of mild soap, and a soft brush, then pat dry. Store each piece separately to avoid scratching. Reach out any time if you have questions about care.
