RJC Member

We are proud to be member of the Responsible Jewellery Council. We are now preparing the audit to pass the RJC COC certification. Our target to reach the certification is end of 2022.

This standard defines an approach for companies to handle and trade gold, silver and platinum group metals in a way that is fully traceable and responsibly sourced. Chain-of-custody (CoC) certification is voluntary and complements certification against the RJC’s Code of Practices, which is mandatory for all RJC members. This is a ‘living document’ and the RJC reserves the right to revise this standard based on implementation experience and emerging good practice. The version posted on the RJC website supersedes all other versions. Please see: www.responsiblejewellery.com

Today, the Thai Gem and Jewelry Traders Association is recognized and embraced by both the government and private sectors of Thailand and several countries as the primary gems and jewelry trade association in the Kingdom that operates at an international standard.

A D&B DUNS number is a nine-digit number that is recognized as the universal standard to track businesses worldwide. It is designed to enhance the credibility of your business and enable potential customers, lenders and suppliers to learn about your company. This number can be a major factor in business credit decisions.

It will come with an attached "Paydex" score, from 0 to 100. 75 and above is considered an excellent score. This score can be compared to a credit score, but for the business.
