Gem Authenticity

We'll be using our blog to shed more light not just regarding the authenticity of our natural gem stones but also it was a journey for us to fulfil our goal of bringing authentic and certified natural gemstones to you.

Not only will you be able to enjoy owning a piece of mother nature's finest product at a great price, having a certification would also meant that the value is ascertained for you.

We believe in transparency, henceforth we would also be sharing some information regarding the different authenticity centres that we liaise with for our products. Over at our end, gemstones are actually procured first before we come out with jewellery designs. 

  • A simple summary
  • Website
  • Address
  • Sample Photo of the Certification

However, of course there are also countless fake certifications and also shell companies that try to pass off lab grown/synthetic gemstones as real ones. We even have experience with local businesses who didn't specify the nature of the gemstones in hopes that consumers would not question them. We do take all these into consideration before doing our due diligence to make sure that the gemstones we sourced are authentic and certified.

Some things that we would be looking out for and sharing with you:

  • Double Checking with other Suppliers
  • Credentials that was provided
  • Confirm the Registration/License Number with CNAS/CMA
  • Company's Official Website 
  • GB/T Gem Handling Standards

CMA (China Metrology Accreditation) and CNAS (China National Accreditation Service for Conformity Assessment) are the national accreditation bodies of China that are responsible for the accreditation of gemstone certification and inspection. This would greatly help us verify the integrity of the gem testing centres that our gemstone suppliers are using to certify their gemstones before it is shipped over to us. 

CMA is also the highest award offered by the National Association of Jewelry Appraisers. To receive it, one must have at least seven years of appraisal experience, take the NAJA appraisal studies course, pass a comprehensive theory and practical appraisal examination, and have a NAJA or AGA Certified Gem Laboratory.

GB/T 16553 is an example of an alphanumerical code used to represent the Gem Testing standards. We will be sharing what each code represents to help you understand what are the respective industrial standards these codes are representing. I'll be attaching a link below for some optional extra reading.
