How hard is a Takara?
Takara’s are pure diamond, and rate 10 or 10+ on the Mohs scale. The 10+ aspect refers to previous findings by the GIA and others that lab-grown diamonds are slightly harder and less brittle than natural diamonds. This can be inferred to be a result of ideal nitrogen dispersion in lab-diamonds, and a more perfect crystal structure.
