When investing in gemstones and fine jewelry, it's crucial to ensure you're getting what you pay for. This is where gemstone certifications come in, acting as a trusted third-party assessment of a gem's quality and characteristics. At JewellHub HK, we understand the importance of transparency and quality assurance, which is why we primarily offer gemstones certified by CGL. But what exactly is a CGL certification, and why should it matter to you?
What is CGL?
CGL stands for Ceylon Gem Laboratory , or Canadian Gemlab . It is an independent gemological laboratory that specializes in the identification and grading of gemstones. CGL provides comprehensive reports detailing a gemstone's key characteristics.
What Does a CGL Certificate Include?
A CGL certificate typically includes the following information:
- Gem Identification: Confirms the type of gemstone (e.g., sapphire, ruby, diamond).
- Carat Weight: Precise measurement of the gemstone's weight.
- Measurements: Dimensions of the gemstone (length, width, depth).
- Color Grade: Evaluation of the gemstone's color based on established grading scales.
- Clarity Grade: Assessment of the gemstone's internal and external characteristics (inclusions and blemishes).
- Cut Grade (for Diamonds): Evaluation of the diamond's proportions, symmetry, and polish (Excellent, Very Good, Good, Fair, Poor).
- Origin Determination (if possible): Some CGL reports may include an opinion on the geographic origin of the gemstone, which can significantly impact its value.
- Treatment Disclosure: Disclosure of any treatments or enhancements the gemstone has undergone (e.g., heat treatment, irradiation). This is crucial information, as treatments can affect a gemstone's value and stability.

CGL vs. Other Labs (GIA, Gubelin)
While CGL is a reputable lab, you might also hear about other well-known gemological laboratories like GIA (Gemological Institute of America ) and Gubelin Gem Lab . GIA is widely considered the gold standard for diamond grading, while Gubelin is renowned for its expertise in colored gemstones. The best choice depends on the type of gemstone and the specific information you're looking for.
