Cassiopeia Studs

Chemically, physically, and optically — nothing. Even a professional gemologist needs specialized equipment to tell them apart. Lab-grown diamonds form under the same heat and pressure as mined stones; the address is just different.

We chose lab-grown because they're traceable, responsibly made, and let us set bigger, better stones at honest prices.

Because lab-grown diamonds changed the math — and we price off the new math.

Growing a diamond above ground costs a fraction of mining one. Much of the industry still prices diamonds the way it did a decade ago — and the market would let us do the same. But we exist to make diamonds accessible: an everyday staple, not a once-a-decade splurge. So we price off what diamonds actually cost us today, plus the honest margin a small business needs. Nothing padded, nothing theatrical.

The stones don't cut corners: graded on the same 4Cs as mined diamonds, full specs on every product page, and IGI certification available on any stone 0.5 carat or larger for an additional fee (details in “Are your diamonds certified?” below). The price isn't the catch — it's the point. Diamonds you can wear every day.

Every diamond's specs — carat, color, clarity, cut — are listed in the Details section of its product page. For pieces with stones 0.5 carat or larger, we can arrange IGI certification before your piece ships — fees are generally $25–$150 per stone, depending on stone size, and it adds about a week of processing. Anyone can request a quote. Email hello@zaylanewyork.com to set it up. One note: the certification fee isn't refundable, even if the piece comes back to us.
