What We Do After the GIA Report

A section for Flawless Jewelry, New York

The report tells you the grade. It doesn't tell you which stone to buy.

GIA finalizes clarity at 10x. That's not a shortcut — it's the standard the entire industry agreed to, and it's the standard written into U.S. trade rules. It exists so a VS1 means the same thing in New York, Antwerp, and Mumbai.

We don't grade against a different standard. Nobody does, and anyone who tells you they do is selling you something.

What we do is different, and it's the part that actually decides how your ring looks: we go through the stone at 30x and higher, on a GIA gem microscope under darkfield illumination, before we'll put it in the case.

Not to re-grade it. To decide whether we'll sell it.

Two diamonds, same certificate, different ring

Here's the thing a grade can't capture.

Take two SI1 diamonds. Same weight, same color, same cut grade, same clarity, same lab. On paper they're twins. In the tray, one comes alive and the other looks flat — and the reason is sitting inside them.

Clarity grading weighs five things: the size, number, position, nature, and color of what's inside. The grade compresses all five into two characters. But position and color are what you actually see.

A dark crystal parked under the table interrupts light on the way in and again on the way out. You lose brilliance in the middle of the stone, where your eye goes first. Move that exact same inclusion out near the girdle where a prong will cover it, and it does nothing at all. Same grade. Completely different diamond.

Thirty power is how we tell those two apart before you ever see them.

What we're looking for at high magnification

Color and relief of the inclusions. White and transparent features disappear. Black, dark brown, and metallic ones don't. Two stones can carry identical grades and look nothing alike because of this alone.

Position relative to the table. Center-table under the crown is the worst real estate in a diamond. Under a prong is the best. We map it before we buy.

Whether it stays hidden once it's set. A feather that vanishes behind a prong in a solitaire is exposed in a bezel or a low-profile setting. We check the stone against the setting you actually want, not in the abstract.

Durability. Feathers that reach the surface — especially near the girdle or a corner on a princess or emerald cut — are a risk during setting and over a lifetime of wear. That's a structural question a clarity grade isn't designed to answer, and it's one of the main reasons we pass on stones.

Treatment evidence. Laser drill holes and fracture filling are disclosed on a GIA report, but we confirm with our own eyes. A stone changing hands more than once is a stone worth double-checking.

Cut execution up close. Facet junction alignment, polish marks, extra facets, transparency and haze — things a "Very Good" symmetry grade covers a range of, and that we'd rather see for ourselves.

Why we'd bother

Because most of what makes a diamond beautiful lives in the gap between two stones with the same report.

If you're buying by certificate online, you're buying a stone nobody looked at with you. You get the grade and you take your chances on the five things the grade compressed. Our job is to do that comparison work in advance — look at thirty stones, reject twenty-six, and put the four that actually perform in front of you.

That's the difference between grading and selecting. GIA grades. We select.

And you're going to look too

The last part matters as much as the rest.

When you come in, the scope is yours. We'll put the stone under it, walk you through it layer by layer, and show you exactly what's inside — the good and the honest. If there's a feather in there, you'll see the feather. If there's a dark crystal we'd rather you not buy, we'll say so and show you why.

You'll walk out knowing your specific diamond, not just its report number.

That's the standard we hold ourselves to. Not stricter than GIA — GIA sets the grade, and we trust it. Stricter about which graded stones are good enough to carry our name.
