Hardness scales for gemstones and minerals

Thegemac.com Welcome to Gem Dictionary by The Gem Academy! Let’s learn about ‘the hardness scales used to express the hardness of gems and minerals… ‘Hardness’ refers to a specific physical property of gems. Hardness is the ability of a material to resist scratching and abrasion. Often, we may hear a diamond had the “best hardness as its 10 out of 10”, or maybe that a gem has a “hardness of 8 so that’s just two hardness away from diamond” (True quotes that I’ve heard!!)… Let’s find out more about the hardness scale and why one of these above statements is not true!
