Inspect the stone
Updated November 2026
The certificate says what the stone is. This check says what it looks like — because two stones with identical paperwork can sparkle very differently, and the only grades worth paying for are the ones your eyes can see.
The check: excellent cut, eye-clean at arm's length, white against the metal it's going in — confirmed on 360° video or in person under normal light, not just under the jeweler's halogens.
Run it
- Cut first, always. Excellent (GIA) or Ideal cut on rounds, no exceptions. Cut is the sparkle; a poorly cut stone looks dull at any color or clarity, and the premium over a Very Good cut is small.
- The eye-clean test. Hold the stone (or the 360° video) at 10–12 inches. If you can't find an inclusion without being told where it is, it passes. VS2–SI1 stones usually pass; verify SI1 on video every time.
- Color against the metal. G–H looks icy white in any setting. I–J looks just as white in yellow or rose gold — and costs 20–30% less. Paying for D–F color is paying for a lab document, not a visible difference.
- Normal light, not store light. Jewelry counters are lit like operating rooms for a reason. Ask to see the stone near a window or under plain office light — that's where it'll live.
- Fancy shapes: hunt the bow-tie. Ovals, pears and marquises can carry a dark bow-tie shadow across the middle. Some is normal; a heavy one kills the look. Video or in person, never from a stock photo.
The sweet-spot card
| Spec | Buy | Skip paying for |
|---|---|---|
| Cut | Excellent / Ideal | Nothing. This is the one no-compromise line. |
| Color | G–H (I–J in warm metals) | D–F: a 20–40% premium invisible on a hand. |
| Clarity | VS2–SI1, verified eye-clean | VVS/Flawless: microscope perfection at telescope prices. |
| Fluorescence | None–Medium is fine | Actually a 5–15% discount — and in I–J stones it can make the stone look whiter. Quiet bargain. |
What this check saves
Moving from D/VVS1 to G/VS2 on a 1 carat natural stone saves roughly $2,000–$4,000 with zero visible difference once it's set. That's the setting paid for, or most of a honeymoon flight. The price side of this — what the right specs should cost — is check 3.
