The seller standard

Almost every guide to buying crystal is written by someone selling it. This page is the opposite: it is the checklist we apply to a seller, published in full, so that you can apply it yourself to any seller — including one we have never heard of.

The four things a seller has to be able to answer

One
Has this been treated, and how?
Dyeing, filling and coating all require specific disclosure under international trade practice; heating requires general disclosure. A seller who cannot say which of these applies to a stone does not know what they are selling.
Two
Natural or laboratory-grown?
These are different questions from “is it real quartz”. Hydrothermally grown quartz shares the composition and structure of natural quartz, so a report that names the species answers neither question.
Three
If there is a report, which laboratory issued it and what did it test for?
A report is only as useful as the test it names. “Quartz” on a certificate is a material identification, not a finding on origin or treatment.
Four
What happens if the answer above turns out to be wrong?
A stated returns position, in writing, before the sale.

What being listed here does not mean

It is not a guarantee of any individual stone. It is a record that the seller answered the four questions above in writing and agreed to keep answering them. Every stone still has to stand on its own examination, and where a specimen is worth more than roughly US$300 the correct step remains a report from a testing laboratory.

For sellers

The standard is open. Answer the four questions in writing and we will publish the answers next to your name, unedited. Nothing is paid for and nothing is removed on request except by correction.
