A diamond or fine gemstone is one of the largest purchases most people will ever make — and one of the least understood. The cuts, the grading language, the optical tradeoffs, what actually matters versus what a retailer wants you to think matters: almost none of it is explained anywhere neutral.
The Cut Guide exists to change that. We are an independent reference for diamond and gemstone cuts — the specifications, the optical behavior, the real tradeoffs. The place you come before you set foot in a showroom or open a browser tab to shop. The site that gives you the language and the knowledge to make a major purchase with confidence, rather than be guided toward one.
We love jewelry and cut stones. We believe deeply that the more you understand them, the more you appreciate them — and the better the decision you'll make. That belief is what this site is built on.
An independent reference. Not a marketplace, not a recommendation engine. Every cut documented here is treated the same way — with the same depth, the same honesty, and the same editorial independence from what you ultimately choose to buy.
We carry no inventory and sell nothing. We have no retailer relationships, no vendor partnerships, and no manufacturer access arrangements. No one sends us stones, no one pays for coverage, and no one sees content before it publishes. Every specification, performance score, and caveat on this site is sourced from published gemological research, GIA standards, and direct analysis — not from anyone with a financial interest in what you buy.
We may eventually use affiliate links — a standard arrangement where we earn a small commission if you click through to a retailer and make a purchase. If and when that changes, we'll say so clearly here. What it will never change is this: affiliate relationships do not determine what we write, how we score cuts, or which caveats we surface. The editorial is not for sale. That's what "editorially independent" actually means.
Everyone deserves to understand what they're buying before someone helps them buy it. The jewelry industry is full of expert salespeople, showroom lighting, and carefully chosen language — none of it designed to make you a more informed buyer. We think you should be educated before you're cajoled. That's what this is for.
