Documentation
Certificates, and what they do not cover
A certificate is only useful if you know which question it answers. Below is each document we hold, the question it answers, and how a buyer can verify it independently.
| Document | Scope | What it records | How to verify |
|---|---|---|---|
| GRA grading card | Stone | Issued with moissanite to record weight, shape, colour grade and measurements. It is a grading card, not a diamond laboratory report. | Check the card number against the GRA registry, then match the measurements to the stone. |
| IGI report | Stone | Independent laboratory report for lab-grown diamonds and, on request, for moissanite. Records carat, colour, clarity, polish and symmetry. | Verify the report number on igi.org and compare the plotted inclusions to the physical stone. |
| SGS material test | Metal | Tests cadmium, lead and nickel release on the finished alloy and plating. The report is tied to a submitted sample, not to the whole catalogue. | Ask for the report matching the metal and plating of your order. |
| CTT nickel release | Metal | Nickel-release testing to the standard used in European market compliance work. | Confirm the test method and the plating thickness used for the sample. |
| SMETA / Sedex audit | Social | Four-pillar social audit covering labour standards, health and safety, environment and business ethics at the site. | Sedex membership and audit date can be checked through the Sedex platform. |
| Hong Kong Customs AML | Registration | Anti-money-laundering registration for the Hong Kong trading entity. | Registration details are provided with contract documents. |

What we deliberately do not claim
A number of jewelry sites list ISO 9001, “conflict-free” sourcing and laboratory grading on every stone. We hold material-test and social-audit documents instead, and we say so plainly: our moissanite grading is our own visual QC, the GRA card records the stone, and independent diamond grading comes from IGI or GIA when an order justifies the cost.
That position is less impressive on a banner and considerably easier to defend in a buyer audit.

Certification questions
Does every stone ship with a certificate?
Moissanite ships with a GRA card by default. Lab-grown diamonds ship with an IGI report when the order value justifies it; smaller melee is supplied with batch documentation instead.
Can you send certificates before I place an order?
Yes — a document pack covering metal tests, social audit and a sample grading card is sent on request, usually within one working day.
Is the SGS report valid for every style?
No. Material tests attach to the specific alloy and plating submitted. If your order uses a different metal, ask for the matching report or for a fresh test.
