Have Some Thoughts on Lab-Grown Diamonds? Tell the RJC Now
The first round of input on RJC’s new Laboratory Grown Material Standard is open until Dec. 17.

RJC announced in September it had begun crafting an industry standard for manufacturers and retailers that deal in lab-grown gemstones.
Separate from RJC’s existing Code of Practices, it will aim to establish best practices for the use of lab-grown diamonds and gems in jewelry, including social, environmental, and business integrity requirements.
The council said it will be mandatory for all RJC members who handle lab-grown materials to operate according to the standard.
It expects to release the Laboratory Grown Material Standard by June 2022.
The development of the LGMS includes a minimum of two rounds of public consultations and input from the multi-stakeholder Standards Committee to ensure it sets a benchmark in the industry for best practices working with lab-grown materials.
The first round of consultation takes 60 days.
Those interested in commenting can do so on this form until Friday, Dec. 17.
