Gem Authenticity

Gem Authenticity

We will be using our blog to share with you on the process in which we verify the authenticity of our natural gemstones and our journey 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 done would also mean that the value is ascertained for you.

In Paradixia, we believe in transparency. Hence, we would also be sharing information regarding the different authenticity centres that we liaise with for our products. Over at our end, gemstones are meticulously handpicked first before we come out with the jewellery designs. For each of the dedicated posts on the authenticity centres, we will cover the following: 

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

Of course there are also countless fake certifications and 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. Hence, we take rigorous action in making sure that the certificates issued are authentic. 

Some measures that we perform include:

  • Double Checking with other Suppliers
  • Verifying the Credentials that was provided
  • Confirming the Registration/License Number with CNAS/CMA
  • Ascertaining that the Company's Official Website is valid 
  • Checking against the 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 that the code entails.
