Nature provides gemstones worth millions through simple arrangements of molecules and elements within minerals. Gems are classified as precious or semi-precious based on their mineral composition and abundance. Diamonds are the hardest material, made of carbon atoms formed under extreme heat and pressure. Emeralds are varieties of beryl containing beryllium, aluminum, silicon and oxygen that get their color from traces of chromium and vanadium. Rubies are a form of corundum made of aluminum oxide that derive their red hue from small amounts of chromium.

2. Nature’s bounty is not limited to, air, light and water. Its generosity has also
provided us with gemstone worth millions. They are formed by simple molecules
or individual elements in repeating chains, sheets or three-dimensional
arrangements.
These molecules are differently arranged in different gemstones, which
determine the characteristics of the stone. In fact, the gem information can be
done on the basis of the arrangement of the molecules.

3. PRECIOUS GEMSTONES AND THEIR
COMPOSITION
• Interestingly, gemstones have been classified into precious an semi-precious
classes. This depends on the way the minerals have coagulated to form the
gemstones or how abundant they are.

4. DIAMONDS
They are made of carbon atoms are considered to be the hardest material on
earth. In fact, diamond cutters are used for cutting glass. Diamonds are found
in various places on earth and are formed under extreme temperature and
pressure.

5. EMERALDS
They are formed by minerals called beryl, which has a chemical formula with a mix of
beryllium, aluminum, silicon and oxygen. Additional traces of Chromium and Vanadium
lead to the color which the gemstone offers.

6. RUBIES
Ruby gemstone is formed of a mineral called corundum, which comprises
aluminum oxide. The red shade is formed by dashes of Chromium present in it.
Corundum also forms sapphires in several colors caused by the presence of
trace mixtures of iron, titanium and chromium.

7. FACTORS ABOUT GEMSTONE
• Some factors that classify minerals and gems are hardness, luster, color,
density and magnetism. They are also identified in the manner they break
or the type of streak they leave with a streak tool.
• You can get more information about different gemstones and their
composition from the Internet. Otherwise, you can also speak to a certified
gemologist who would be able to guide you with authentic and certified
gemstones
