Our story

Selling diamonds online since 1999.

We started selling diamonds online in 1999, when most of 47th Street still did business by handshake. Our founder was among the first fine jewelers to sell diamonds directly to customers online, a move JCK covered in 2002. Today we have our own factory, with headquarters in Israel and in New York at 580 Fifth Avenue, and every piece is still checked by our own team before it ships.

Why lab-grown

  • A real diamond

    Same carbon, same hardness, same fire as a mined stone. Only the origin is different.

  • Bigger for less

    Your budget buys a larger, cleaner stone than it would in a mined diamond.

  • Nothing to hide

    Every stone's origin is known. No mines, no guesswork.

★★★★★
The diamond earrings were a gift for my daughter, so I wanted a pair that was graded and certified for insurance purposes. She was very pleased with the quality of the earrings and consequently, I was very pleased with the price and purchase.

Are lab-grown diamonds real diamonds?

Yes. They are physically, chemically and optically diamonds, and a jeweler's tester reads them as diamond. Every piece we sell comes with an IGI certificate.

Is it solid gold?

Our Fine Gold pieces are solid 14K gold, stamped. Our Everyday line is 14K gold over solid sterling silver, and every product page says clearly which one you're buying.

Can I return it?

Yes, within 60 days of delivery, in original condition. Return shipping is on us.

Can I resize a ring?

Yes. Tell us the size at checkout or email us after you order. Rings get one free resize in the first year, and every piece has a lifetime warranty (see our Warranty page).
