[QUOTE="Diggerdude, post: 18087, member: 308"] Bit hard to identify from the pic , but the biggest difference between garnet and ruby is the hardness. Try scratching them with something that's tungsten carbide ( grinding bit etc ) garnets will scratch, ruby won't. The difference between zircon and garnet is a bit harder without studying the crystal structure. The local geology will give you a good idea though. Garnets are a product of metamorphism, therefor associated with metamorphic rocks. Zircon are usually associated with felsic igneous rocks ( light granites ). Checkout a geo map of the area.
