15.30 Ct Total | E Color | VS1 Clarity | Round Brilliant | Eternity Tennis Necklace | 17 Inches
Fifteen carats set continuously around a 17-inch strand of solid 14K gold. An eternity setting means the line never breaks — there is no plain stretch of chain at the nape, so the necklace reads the same whether you are facing someone or turned away. At this weight it is unmistakably a statement piece.
E color sits near the top of the colorless range, and VS1 clarity is clean to the eye. Every stone is prong-set by hand in our New York City studio in the Diamond District. Choose 14K white gold for a bright, cool line, or 14K yellow gold for warmth against the diamonds.
Lab grown diamonds are real diamonds — not simulants, not cubic zirconia. Grown above ground under the same conditions as mined stones, and sold direct from the maker, so your investment goes toward the diamonds, not a retail markup.

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 individual diamond of 1.00 carat and above is independently certified by IGI and laser-inscribed for verification.
Complimentary fully insured FedEx shipping within the US, signature required on delivery. Dispatch time is shown above the Add to cart button; FedEx transit is 1–2 business days after that. 30-day returns on unworn pieces; a $75 insured return-label fee is deducted from your refund.
Certification is per individual diamond, not per pair or per piece. Every diamond of 1.00 carat and above arrives with its own IGI grading report, and the report number is laser-inscribed on the stone's girdle — verify it anytime at igi.org. Diamonds under 1.00 carat (for example a 1 ct total-weight pair, which is two 0.50 ct stones, or the stones in tennis bracelets and eternity bands) are graded to the same standards but are not individually certified.
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.
