When discussing about gemstone jewelry, it is necessary to know a little about gemstones. They are organic materials that have been cut and polished into beautiful items by expert craftsmen. Minerals are naturally formed solid chemical compounds found in rocks. The specific hardness and color of each mineral is due to its fixed chemical composition and regular atomic structure.

Gemstones come in different colors and varieties. These include natural gemstones, synthetic gemstones, imitation gemstones and composite gemstones.

Natural Gemstones: These gemstones are priced according to quality and availability. Certain natural gemstones are a lot cheaper than others precisely because they are available in abundance. The quality of a gemstone is usually determined by the number of inclusions it has, its color and brilliance. Natural gemstones are often treated to enhance their natural beauty. While heat and radiation affect the color of a gemstone, oil and wax is also used to fill inclusions within a gemstone.

Synthetic Gemstones: These are produced artificially in a lab and resemble a natural gemstone  in chemical properties, physical looks and color.

Imitation Gemstones: These are simple colored glass cut into a gem shape and are very cheap and good looking alternatives to the natural gemstones. They resemble a natural gem only in appearance and can be very easily detected as they have swirl marks of glue under the stone and the glass has a few scratches.

Composite Stones: These stones are made by painting a coating chunk from glass within a thin film of the real stone which it is trying to imitate.

Gemstone jewelry comes in a wide variety of colors and can be used for traditional attire as well with trendy clothes. Depending on the color of these gemstones, they are called by different names. The different colors are formed due to variations in the mineral composition and the presence of traces of other compounds.

Ruby is one of the most precious gemstones available. It comes from Corundum , which is an aluminum oxide mineral. The distinctive red color of ruby is because of the color of the Corundum crystals. But, Corundum occurs in a wide range of other colors too, depending on the amount of traces of other elements such as iron, titanium and chromium found in the original Corundum.

When titanium and iron are found in Corundum, it gives rise to a blue color which leads to the formation of Sapphires . Sapphires can also be found in other colors depending on the presence of other elements in the base mineral.

Due to the beautiful shades of green, emeralds are highly preferred and valued among gemstones. They are formed from Beryl, a silicate of aluminum and glucinum. Emeralds need to be handled with care as they can be easily scratched.

There are many factors that determine the price of a jewelry piece – the type of metal used for crafting, the type of gemstone, and the quality of craftsmanship. Another factor that affects the price of a jewelry piece is the size and quality of the gem. Most of the gemstones are measured in carats. The higher the carat weight, the larger the stone, and the more valuable it is.
