PRECIOUS STONES:
Precious stones (or gemstones) are minerals used in jewelry making and
sometimes industrially. Since they are scarce, their material value is
high. Except for diamonds, rubies, emeralds, and sapphires, they are
generally considered semi-precious stones. Some rock types such as lapis
lazuli and some organic materials such as amber are also considered
semi-precious stones because they are used in jewelry making.
It can take millions of years for a crystal to form in nature. A small
part of these are found and processed by people in different ways. After
processing, its quality, size and purity determine its value. This
depends on a few different factors.
