Do Diamonds scratch glass?
I have heard of this happening when a diamond has a flaw in it. A jeweler will be able to let you know about diamond flaws. Yes - A diamond can chip or fracture irrespective of flaws. While diamonds are quite hard (scratch resistant), they all have 'fracture planes' as a result of how the carbon atoms are ordered, and thus their toughness (resistance to fracture or chipping) is good but not great. You can smash a diamond with a hammer for example. I know several diamond cutters who do the bulk of their work recutting chipped diamonds, so it happens far more often than people would think.

Why do people check to see if a diamond is real by rubbing it against glass?
People use the glass test to check if a diamond is real because diamonds are harder than glass. If a diamond is real, it will scratch the glass, whereas a fake diamond will not leave a mark. This method is not foolproof and other tests are recommended for a more accurate assessment of a diamond's authenticity.
Is jade harder than a diamond?
Jade has more density than a diamond. While a nice size jade block "may" fracture a diamond; the diamond "will always" scratch the jade stone. Many people confuse the diamond with being a strong stone. It is not! In fact the diamond is easily fractured. The diamond is however very hard (not strong but very hard) Diamonds can scratch just about every surface on earth.
