Diamonds: 4.00 Ct Total | Cushion Shape | 3.5mm | Sizes 4–9
A full-eternity band set with cushion-cut diamonds, end to end. Each stone is D-E color and VS1 clarity — the kind of specification that used to mean a significant retail premium. Ours are 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 as mined stones, graded to the same standards, and sold direct from the maker so you get more diamond for your investment.
Wear it alone as a statement band, stack it, or pair it as a wedding band. Built to be worn daily and passed down.

Please Note: Total diamond carat weight may vary depending on ring size. Each eternity band is custom made using the same diamond dimensions for a perfect look. Because larger ring sizes require more diamonds and smaller ring sizes require fewer diamonds, the total number of stones and total carat weight will vary accordingly.
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.
