Chondrodite is a neosilicate and a member of the humite family of minerals. It is formed in hydrothermal deposits and associated with dolomite, skarn, and serpentinite. It is closely related to clinohumite and impossible to differentiate from it with standard gemological tests . As a mineral, it is the most common member of the humite group but gem quality pieces are uncommon. The name is derived from the Greek for "grain" in allusion to its occurrence in isolated grains.

Other members of the humite group include; alleghanyite, clinohumite, manganhumite, sonolite, ribbeite, leucophoenicite, and jerrygibbsite.
In terms of gemology, there is no easy way to separate clinohumite from chondrodite and only best equipped labs can manage it. |
