IGI - International Gemological Institute

IGI holds a Supreme position in the Gemological world and is recognised worldwide for diamond grading and coloured gemstones. IGI screens every gemstone using state-of-the-art technologies to determine naturally mined, the laboratory has grown or simulant origin. Experienced graduate gemologists conduct further assessments in controlled conditions, detailing relevant gemological characteristics according to the strictest international system. A detailed photograph will be included, and the country of origin is stated if gemological analysis conclusively reveals it.


GIA - Gemological Institute Of America

GIA is a Charitable Trust ensuring the public by holding Highest Standards for Gems and Jewels. The GIA Identification & Origin Report describes whether the stone is natural or synthetic, identifies the type of gemstone along with an opinion on the geographic origin of the stone, and includes any detectable treatments. This report also contains a detailed description of the gemstone such as cut, shape, weight, measurement, and colour, and includes a photograph of the gemstone. This certification is available for ruby, sapphire, emerald, Paraiba tourmaline, red spinel and alexandrite only.


All Gemstone Reports includes

The gemstone's description (natural or laboratory-grown) as well as its shape, cutting style, measurements and origin.

1. Report Number

Each report has a unique 10 or 11-digit number, e.g. 2021-078888. This individual document number is critical to substantiate a report’s authenticity.

2. Date

The date on the report identifies the date when the item was received and processed for examination at one of our gemological laboratories.

3. Identification

The examination result of the tested gemstone such as mineral and/or variety name. Stones of natural formation are identified as ‘Natural’ before the item name (e.g. Natural Ruby). Items produced from a synthetic crystal will bear the term ‘Synthetic’ in front of the name (e.g. Synthetic Ruby). Stones that have undergone rigorous treatment will be marked as ‘Treated’ in front of the identifying name (e.g. Treated Natural Ruby).

4. Color Photo

A full-colour image was captured at the time of gemstone testing. Colour and size of the actual gemstone.

5. Weight & Dimensions

Describes the weight in carat (ct) and dimensions (length, width, depth) in millimetre (mm) of the tested item. The carat weight is shown including two decimal places.

6. Shape / Cut

Describes both the shape (girdle outline) and the cut of the tested item. Shapes can be round, oval, octagonal, fancy, etc. Cut refers to the facet pattern, such as brilliant cut, step cut, polished, step/step, etc.

7. Color

Describes the spectral hue of the tested coloured gemstone (e.g. red, blue, green, yellowish-green, etc.).

8. Comment

Describes observations noted on the gemstone that could signify possible enhancement (e.g. heat-treatment, clarity enhancement using oils or resins, dyeing etc.).

9. Origin

GIA coloured gemstone identification reports include a geographical origin opinion. A gemstone’s determination of authenticity and country of origin is based on testing the physical and chemical properties of that stone. A conclusion is reached after examining the internal characteristics (e.g., inclusions and growth structures) using standard gemological devices and modern analytical instruments (e.g. ED-XRF, FTIR, UV-Vis, PL, and LIBS spectrometers).

10. QR Code

A unique QR (Quick Response) code printed on each gemstone report can be used to verify that report's authenticity (License Agreement applies). Using a smart device with a QR-scanner app, scan the code and verify if the report appears in our database.
