The revised definition seeks to expand…

De Beers recorded a 38% year-on-year increase in diamond production in the third quarter of 2025, reaching 7.7 million carats, with a significant proportion of the increase due to higher output at the Jwaneng mine in Botswana.

Regional Production Overview Production in Botswana, De Beers’ largest contributor, rose by 51 percent to 6 million carats. Output at the Jwaneng mine more than doubled to 3.2 million carats, driven by the processing of higher-grade ore ahead of a planned plant maintenance shutdown…

A new model for assessing gemstone durability, developed by Kennon Young of the Vermont Gemological Laboratory, has been introduced to the trade. Known as Young’s Durability Scale, it proposes a weighted, multi-factor approach to durability that extends beyond the traditional reliance on the Mohs scale of hardness. Beyond Hardness: A Revised Approach to Durability The Mohs scale, first introduced in 1812, has long served as the standard for evaluating gemstone wearability. However, it primarily measures surface scratch resistance and does not account for other critical aspects of durability. The new model by Young incorporates three core factors: hardness (35 percent…

The examination took place in July 2025 at the GIA laboratory in Gaborone, Botswana.
