The “Truth” About At-Home Tests: Why They Are Unreliable for Business
Many “at-home tests” circulate online, such as the fog test or the water test. We must state clearly: for commercial sourcing, these methods are extremely unreliable and fraught with risk.
- The Fog Test:Can only crudely distinguish a diamond from glass. It cannot differentiate a diamond from moissanite, as high-quality moissanite also has excellent thermal conductivity.
- The Water Test:Only works for telling a diamond apart from very low-density imitations. It is completely ineffective against lab-grown diamonds, moissanite, or high-quality CZ.
- The Scratch Test:Absolutely forbidden! This destructive test will cause irreversible damage to both genuine diamonds and their simulants.
The B2B Core Takeaway: Relying on these amateur methods to make purchasing decisions is a significant and irresponsible risk for your brand and capital.

Professional Identification: The GBAN JEWELRY Internal QC Process
As your reliable Jewelry Supplier, we use professional gemological instruments for cross-verification before any diamond enters our inventory or leaves our factory:
- The Thermal Conductivity Tester
- The Principle:Diamonds are the best thermal conductors in nature. A thermal tester uses a probe to measure the rate at which heat dissipates from the gemstone’s surface.
- Its Function:This is the fastest and most effective method for distinguishing diamonds from all common simulants (like Cubic Zirconia). However, it cannot distinguish natural diamonds from moissanite.
- The Electrical Conductivity Tester
- The Principle: Diamonds are electrical insulators, while their primary simulant, moissanite, is an electrical conductor.
- Its Function:This is the “gold standard” for differentiating diamonds from moissanite. Through the “dual verification” of thermal and electrical conductivity tests, we can be 100% certain that a stone is a diamond (either natural or lab-grown).
- Microscopic Examination
- The Principle:Under a 10x or higher magnification gemological microscope, an experienced gemologist can observe a stone’s internal features (inclusions), girdle, and facet details.
- Its Function: Used to assess the diamond’s clarity and look for characteristic differences between natural vs. lab-grown diamonds.

The Ultimate Guarantee: The GIA Certificate – A Diamond’s “ID Card”
For higher-value diamonds, instrument testing is not enough. An authoritative third-party certificate is the only final guarantee.
- What is a GIA Certificate: A report issued by the world’s foremost authority in gemology, the Gemological Institute of America (GIA). It details a diamond’s 4Cs, dimensions, fluorescence, and other key characteristics, complete with a unique report number.
- The GBAN Authenticity Promise:
- All high-value diamonds from our Factory Direct supply can be accompanied by a matching GIA certificate at your request.
- You can use GIA’s online report check service to enter the number and verify that the diamond’s details are a perfect match.
- For our Jewelry Custom services, we can laser-inscribe the diamond’s GIA report number onto its girdle, creating an unfalsifiable link between the stone and its certificate.
