Gem Stones

My sister has been watching Steven Universe and studying geology in school so she know wants gems. Does anyone know anything about them? Or tips I can share with her?

depends on what part she wants to know. Does she want to know the culture that people have that centers around gems? What gems 'meanings' are? Magical properties? What their status is in religions? What parts they play in history? Why certain ones are valued more than others? The rarest types? How they are integrated into jewelry and clothing? So many questions can be asked, and many more answers can be given.

pressure. gems are often found in volcanic tubes. as for cutting them, not sure about that except one should wear goggles for it. I know there is a good book for it, but I can't remember what it is off the top of my head. I tend to go more with the folklore about gems.

Gems are more mineral and rocks being formed by the pressure the magma produces when trying to scape to the surface. The more presure the more precious the gemstones are formed when the magma solidifies. Is a process that last a lot. And is more complex than that but you can always search for it.

When it comes to diamonds, pure ones are white and very rare. Diamonds with colors are actually diamonds with impurities, trace amounts of other elements. Also know that diamonds made in the earth are identical to ones made in a lab.

Oh gawd... My mind has been so wasted with this... Still TRYING to forget all that... Well thing with geology is that it is the understanding of the mineral terrain, not the minerals themselves. Now gemology, is of course, understanding the mineral itself, not the terrain of it. Either way you are getting involved with minerals, but does she prefer knowing the structure from a land-bases, doing fieldwork, and understanding weather damage structure to an area(Geology) OR getting down to the ground and finding the minerals themselves, from common quartz, to rare gemstones like emeralds, diamonds and such, and taking them out?(With a permit of course)(Gemology) I'd say taking BOTH gemology AND geology has many benefits, especially as a career, or if she wants to have them as one. It also works as a hobby. Another note: Diamonds are actually quite common, they are just worth so much because they trickle them out, to control the circulation. More notes: Now gem cutting, or a lapidary, doesn't have to have a degree in gemology or geology, just a good knowledge of them. Now, cutting them, can be quite dangerous, not because you weren't wearing any goggles, which you don't really need, but because many are poisonous. Turquoise has arsenic, so cutting it without a good amount of water will be bad, wearing a good respirator is good, but not all stones are poisonous, just knowing what is what. If you want to know more ask me, 'cause I've been hammered with this shit, and I never thought someone would ask the question of rocks =_=... Anyhow...
