The LMNY Guide
Fine Jewelry Buying Guide
How to buy a piece you'll never regret — stones, settings, budgets, and the questions worth asking.
Start with the Stone
Every diamond is graded on the four Cs — cut, color, clarity and carat. Of the four, cut does the most work: it is what makes a stone alive in the light. We favor exceptionally cut natural stones, then balance color and clarity to the eye rather than the certificate alone. A diamond should be beautiful on a hand, not just on paper.
Three Ways to Buy
Natural & Fine Jewelry
Our flagship: natural diamonds and colored gemstones, designed in New York and crafted in Italy. Made to be worn for decades and handed down.
The Pre-Owned Maison
Authenticated estate pieces from Cartier, Van Cleef & Arpels, Bvlgari, Tiffany & Co. and other great houses — history you can wear, verified by our specialists.
Peaceful Diamonds (Lab-Grown)
Certified lab-grown stones with the same fire at a more accessible price — the modern way to begin a collection before graduating to natural and estate pieces.
Buying to a Budget
A confident budget buys better jewelry than a stretched one. Under $2,500, look to stackable bands, pendants and huggie earrings. Between $2,500 and $10,000, tennis bracelets, statement earrings, and engagement rings open up. Above that, rare stones and signed estate pieces become investment territory — and worth a conversation with us first.
Papers, Provenance & Peace of Mind
Certified stones ship with their grading reports. Estate pieces ship with authentication documentation. Everything ships insured, and everything we make carries a lifetime warranty. If you're ever unsure, ask — no pressure, ever.
