Pregraded Stones?

[WPSon20]

Question...

A stone I was looking at through one of the PS vendors is a "pregraded" stone. I was told this means that the stone has already been graded, but a certificate would not be printed until purchase.

What is the underlying motive behind this? Is this legitimate? Are there pitfalls to avoid here?

Also, how can we obtain angles for pregraded stones?

Thank you.

The wholesaler who actually owns the diamond is holding on to the report, it is pretty common for memo stones.
They can call the wholesaler and get the info from the report.

Good to know.

memo means it is on loan to the dealer or on a list and the jeweler pays for it when it sells.
The wholesaler sometimes holds on to the report to prove ownership and make it a little harder to sell without paying the wholesaler.

I''m not positive about AGS, but what you''re referring to WPSon20 sounds like an EGL "pre-grade"
In such cases the stone has been to EGL who grades it- but does not print the report.
The cost is minimal for this "pre-grade"- about $15-$20
if the person who submitted the stone wants the full report, they pay the difference, but already know what it will say.
The only time GIA does not return the report with the diamond is
1) if it''s a treated stone
2) if the stone is "potentially flawless"- GIA returns the stone with a slip showing the cutter what to "fix" to make it an IF.


Did the seller mention which lab the report was from?
