Answer:
The quality of a rock depends on lots of different factors, such as size, shape, color, presence in nature and more.
Explanation:
The size means a lot because, it this rock is too big, it means that it can be found easily in nature, and that doesn't help to raise the quality of the product. The shape of it needs to be easily manipulated, this means that when someone finds a rock that can't be studied or sold because its shape doesn't fit the patterns, they're not so great on quality of product. the presence in nature is really important, because if it's a rare rock, it's very good to have it in lab to study the components and even discovering new things with researches.
