Beyond the Grading Report

What your ROSI™ Score Report covers

1

Light Performance

Two stones graded Excellent can look nothing alike. ROSI™ reads the actual crown, pavilion, table and depth to score how the stone returns light to the eye, including where it ranks against stones of similar specifications.

2

Face Up Size and Character

Whether the stone faces up true to its carat weight or hides it in depth. Fluorescence and how it pairs with the color grade. Clarity characteristics and where they sit. The details that separate a fine stone from a fine looking report.

3

A Fair Market Read

Your stone measured against live market pricing for its exact specifications, so you know plainly where any quote sits. If the price is fair, your report will say so.

Fair Market Read

“Stones of these exact specifications are currently trading between $11,400 and $12,600 on the open market. The medium fluorescence pairs favorably with E color, and the stone faces up true to its carat. If your quote sits inside that range, it is an honest price.”

Our Standard
“If the stone is right and the price is fair, your ROSI™ Score Report will tell you so, even when the stone is not ours.”

That is the only way a second opinion means anything. Your report also tells you plainly whether this is a stone we would carry in our own collection. And should you want one of ours, it would be our honor to welcome you to the atelier.
