#nycdiamonddistrict

Moving away from mass-produced fashion jewelry and into the era of the modern heirloom.

At Deastra, we’re redefining Premium Lab-Grown Diamond Jewelry. Based in the heart of the NYC Diamond District, every piece is handcrafted in solid 14K gold.

Whether it’s the architectural sharp edges of a Trillion-cut ring or the effortless glow of a diamond necklace, we believe luxury should be as ethical as it is beautiful.

Stop settling for plated. Wear the real thing.

There’s something so architectural about an emerald cut. It doesn’t just sparkle; it reflects.

Our 4.04 ct. Emerald-Cut Three Stone Ring is a love letter to NYC craftsmanship. Set in a warm 14K yellow gold, it’s the ultimate high-end bridal statement for the modern minimalist. Why settle for mass-produced when you can have a unique cut handcrafted in the heart of the Diamond District?

Ethical, lab-grown, and unapologetically brilliant.

Deastra Jewelry // Where the raw energy of the NYC Diamond District meets the future of sustainable luxury.

We don't believe in the "mined diamond" markup. We believe in 14K solid gold, hand-selected lab-grown stones, and artisanal precision that actually lasts.
