Heft describes:

Explanation:
Heft is the quick in-hand impression of how heavy a gem feels for its size. It’s about the perceived weight relative to the stone’s dimensions, not an exact measurement. This is why the description “how heavy an object feels in relation to its size” is the best match. It differs from density, which is a precise mass-per-volume value, and it’s not about color grading or thermal conductivity, which are separate properties.
