The same diamond, the same certification — at the price it always should have been.

The Concierge's Desk

Step inside. A private advisor awaits — unhurried, unbiased, and entirely devoted to you. Ask everything. We answer honestly. Your moment deserves nothing less.

Every Question, Answered Plainly

We spent twenty years as a diamond source for the trade — the jewelers, the ateliers, the designers — before we ever opened our doors to you. That means no boutique on Fifth Avenue, no commissioned sales floor, no chain of wholesalers each taking a cut. You buy at the price the industry has always quietly paid. Same diamonds. Same master artisans. At least 45% less than a traditional jeweler. Read our story →
Yes — without exception. Every diamond is a 100% real diamond, independently graded and certified by the International Gemological Institute (IGI). Because our stones are grown rather than mined, they are inherently conflict-free and fully traceable — no troubled supply chain, no ethical asterisk. The IGI certificate for your exact stone arrives with every order. Understand IGI certification →
It is a real diamond, and no — not even a jeweler can tell by looking. A lab-grown diamond is the same carbon crystal, the same 10-on-the-Mohs-scale hardness, the same fire and brilliance as a mined stone. The only difference is origin: ours is created in weeks in a controlled environment instead of over a billion years underground. Under a loupe, at dinner, on her hand — it is simply a beautiful diamond. See how it’s made →
Typically 40–50% — often more on larger stones. A boutique marks a diamond up 200–400% to carry its overhead. We carry none of it, so a piece a luxury jeweler quotes near $38,000 routinely leaves us — same specs, same IGI grade — closer to $20,000. The diamond on her hand looks identical. The difference stays in your pocket. Browse the vault →
F color, VS clarity or better — four to six grades above what most chain jewelers sell at the same price. Only the top tier of what we receive makes it into the collection; the rest is sent back. Every stone arrives with its IGI certificate stating its exact cut, color, clarity and carat, so nothing rests on our word. You see the grade in writing before you ever decide.
Yes — the precise stone, never a stand-in. Every diamond includes a 360° video so you can study its brilliance and scintillation from every angle, plus high-resolution imagery and the IGI certificate for that individual stone. No stock photos, no guesswork. What you inspect on the screen is exactly what arrives at your door.
That’s what your concierge is for — with no commission pushing you anywhere. Tell us the moment, the person, the budget, and we’ll walk you through shape, size and setting in plain language — often recommending the stone one grade down when it’s the smarter buy. Quiet, patient, honest guidance. Reach a specialist at (207) 679-0656 or concierge@2ndiamonds.com.

Because the name on the box is the one thing you’d be overpaying for. You receive a higher-grade diamond (F/VS), full transparency (360° video and IGI certificate on every stone), a dedicated concierge instead of a commissioned salesperson, and near-manufacturer pricing — at least 45% less for a stone that is, atom for atom, identical to what the boutique would sell you. The real question isn’t why buy from us. It’s why pay more anywhere else. See the difference →
