[QUOTE="zubenelgenubi, post: 3752332, member: 63706"] Do a scratch test. If you have any garnet still that would be an excellent test material. Garnets are just behind sapphire on the hardness scale, and sapphire is the hardest next to diamonds. If your sample can scratch a garnet, and it doesn't have the qualities of a sapphire it is almost certainly a diamond. Diamonds also conduct heat really well, which is why they are sometimes referred to as "ice", because they will feel cool to the touch. [/QUOTE]
