Short answer: the IGI report describes your diamonds, and the BIS hallmark certifies your gold. You can check both yourself: the IGI report number on igi.org, and the hallmark's HUID code in the free BIS CARE app.
The IGI report: your diamond's identity
IGI (International Gemological Institute) is an independent laboratory. Its report for a lab-grown diamond lists:
| Line on the report | What it tells you |
|---|---|
| Report number and date | The unique number you use to verify the report online |
| Description | States that the diamond is laboratory grown |
| Shape and cutting style | Round brilliant, oval, emerald, pear and so on |
| Measurements | The stone's size in millimetres |
| Carat weight | Weight to two decimal places |
| Colour grade | D to Z. Kimi uses E–F, in the colourless range |
| Clarity grade | Flawless to Included. Kimi offers VS and VVS |
| Cut, polish and symmetry | How well the stone is cut and finished (cut grade is given for round brilliants) |
| Comments | The growth method (CVD or HPHT) and any treatment |
| Inscription | If the stone is laser-inscribed, the text on its girdle, usually the report number |
How to verify an IGI report
- Find the report number on your certificate.
- Go to igi.org and open “Verify Your Report”. Type the address yourself rather than following a link.
- Enter the number and compare the carat weight, shape, measurements and grades with your paper report. They should match exactly.
- If your diamond is inscribed, a jeweller can show you the number on the girdle under 10x magnification.
The BIS hallmark: your gold's purity
The Bureau of Indian Standards (BIS) hallmark is stamped on the gold itself, usually inside a ring band, near a clasp or behind a pendant. It has three marks:
- The BIS logo, a small triangle.
- The purity mark: 14K585 for 14KT gold (58.5% pure gold) or 18K750 for 18KT gold (75% pure gold).
- The HUID: a six-character code of letters and numbers, unique to that one piece.
How to verify the hallmark
- Find the six-character HUID on your piece. A magnifying glass or your phone camera's zoom helps.
- Open the free BIS CARE app from the Bureau of Indian Standards and choose “Verify HUID”.
- Enter the code. The app shows the purity and the type of article registered for it. These should match your piece.
