Moissanite scratchers much easier.

  Oh duh. I was so focused on optical qualities I didn’t even think about material ones.

  I need a geologist to explain this one. Moissanite has a Mohs hardness of 9.5. I guess it is easier to scratch than a diamond, but the scratability should be indistinguishable between the two for all practical purposes.

    Not a geologist but Mohs hardness is an ordinal scale so the distance between 10 and 9 isn't well-defined. The numbers are defined as being specific minerals. Diamond (10) is 4x as hard as corundum (9) which is 2x as hard as topaz (8). https://en.wikipedia.org/wiki/Mohs_scale#Reference_minerals https://en.wikipedia.org/wiki/Mohs_scale#Reference_minerals

  Everything scratches easier than diamond. Moissanite is still very hard to scratch.
