How to know the difference between quartz trigons and diamond Trigons

0 votes
How to know the difference between quartz trigons and diamond trigons. The stones all over the surface got bunch of tiny trigons only visible through magnifying glass, very very tiny. Just confused are they common in lot of crystals. Do diamonds have Tiny trigons on the cleaved plane as well?. Heard that Quartz, spinels, diamonds will also have trigons.
If diamond testers don't show it's a diamond,is it still possible to be a diamond?

None of the reference things I could find describes a difference, only the triangle shape of the crystal facets. I am going to assume the trigonal shapes only refer to crystal facets whatever the orientation. There is a range of hardness which diamond testers refer to as diamond. I am sure there are diamonds which fall outside the normal range buuut if it does it would register as another mineral substance like corundum. For instance, diamond is going to fall right there at corundum if it is outside the range but it will not be so far out as to register as quartz. I hope that makes sense. Think of the mohs measurement as a continuum and you get graphite carbon and diamond carbon. Both the same but graphite will always be closest and proximate to graphite and diamond will be closest to diamond, they are not going to go more than a small amount outside the range.
