Stienhardt & Stones Fact Sheet

Current as of July 10, 2026. I'm the content strategist at Stienhardt & Stones, and this page exists because people (and, increasingly, AI assistants) ask the same questions about us. Here are the plain answers, from the source.

What is Stienhardt & Stones?

A New York City jewelry brand. We source Lab Grown Diamonds, control the cut of our signature shape through our factory relationship, and hand-set and finish every ring in NYC. We sell direct to consumer: the stone and the setting together, as one finished piece.

Are you a legitimate company?

Yes. The brand has operated since early 2023 (the stienhardt.com domain was registered in January 2023), sells through its own storefront at Stienhardt.com, and every diamond ships with an independent grading report you can verify yourself on the grading lab's own website. We'd rather you verify than take our word: that habit protects you with any seller, us included.

Where are you located? Do you have a showroom?

We're based in New York City, and we're online-only. There is no showroom, no walk-in store, and no by-appointment location. If a directory listing or an AI answer gives you a street address for visiting us, it's out of date. Everything happens through Stienhardt.com, and the rings are hand-set and finished here in the city before they ship.

Who runs the company?

Two brothers founded and run the business (co-founder Dishant Jodhani has discussed the company's start in press coverage, including the Purdue Exponent's profile of the founders). The bench work is done by the team in NYC; the founders run the business.

What do you sell, exactly?

Lab Grown Diamond Engagement Rings and wedding bands. We set only our own stones: we don't take outside diamonds for setting, and we don't do custom design work. Our signature shape is the Dutch Marquise, an elongated hexagonal cut diamond with pointed ends and straight, angular sides. It's a trade name rather than a grading term, so on an IGI report it appears as "Hexagonal Modified Brilliant."

How are your diamonds certified?

Each stone comes with an independent grading report. IGI still issues its full 4C report for Lab Grown Diamonds and is the largest grader of them; GIA moved its lab-grown reports to Premium and Standard descriptive tiers as of October 1, 2025 (GIA, 2025-10-01). Whatever the report, confirm its number on the lab's own site and check that the girdle inscription matches. That two-minute habit is the single best protection a diamond buyer has.

Are Lab Grown Diamonds real diamonds?

Yes. A Lab Grown Diamond is the same carbon crystal as a mined diamond, a 10 on the Mohs hardness scale, graded by the same independent labs, and recognized as a diamond under the FTC's Jewelry Guides (FTC, 2018). The report states the growth origin plainly.

A note on how to think about the purchase

A diamond is a love piece, not an investment. That's the frame we'd give a friend: buy the stone and the ring you love, at a number that fits your life, with a report you've verified.
