Diamond is also physically harder than moissanite, which is a 9.25 on the Mohs hardness scale compared to a diamond’s rating of 10. While they both feature dispersion, scintillation, and are both considered to be good thermal conductors, moissanites and diamonds are otherwise distinct. Moissanites are slightly more brilliant than diamonds,…
