So we're all familiar with the Moh's scale of mineral hardness, which is based on which minerals can scratch which. But I'm curious about the topic of mineral "toughness", which is based around how easily a given mineral will crack, chip, shatter, etc.

Apparently this is much harder to measure, however, and I can't find much info on this topic online. can anyone help me find a list of minerals / gemstones ranked by toughness, or something similar?

(pic related, jade is generally agreed to be the toughest mineral, supposedly)

Too bad, your career was built by me. You're off model.

This is what I found from a quick google search. There's a few charts, one of which covers the hardness of various minerals and gemstones. There is mention of different scales and methods of measuring aside from Moh's scale, as well. You probably want the Knoop or Vickers scale.
