Gems have intrigued humans for thousands of years. The first known gems used for crafting jewelry were amethyst, rock crystal, amber, garnet, jade, jasper, coral, lapis lazuli, pearl, serpentine, emerald and turquoise. These stones were reserved for the wealthy and served as status symbols.
In ancient times, gems were used as healing stones and talismans on account of their magical powers. Today gemstone jewelry is worn for its aesthetic value and beauty. Some still buy gemstone rings and charms for their mystical properties.

Broadly gemstones can be categorized as naturally found and the human made stones. Natural gems are found in Mother Nature's earth whereas synthetic gems are created artificially. The laboratory gemstones possess essentially the same chemical, physical and visual properties as natural gemstones. Such gemstones are relatively cheaper than natural gem stones. Researchers and gemologists are of the opinion that only natural gemstones offer positive healing powers.
A gemstone is usually measured by weight and size or both. The basic unit for weighing gemstones is the carat, which is equal to one-fifth 91/5th) of a gram. Carats are divided into 100 units called points. For example, a half-carat gemstone would weigh .50 carats or 50 points. When gemstones are measured by dimensions, the size is expressed in millimeters (for example, 7x5 millimeters).
Ruby is one of the most durable gemstones, second in hardness only to diamond. The word ruby brings to mind powerful emotions of passion, romance and power. The ruby is a crystalline form of aluminum oxide infused with trace elements of chromium, which gives the gemstone its red color. The stone gets its name from the Latin word ruber, meaning red. Fine rubies are much rarer than top-quality diamonds and are also far more expensive.
Rubies are the red members of the corundum family of minerals. Corundum of any other color - blue, pink, yellow and others are called sapphire. Natural ruby shades vary from light to dark red and even a purplish cast. Ancient cultures believed that the ruby could cure ailments of the digestive system, energize the blood, and treat the heart. It was worn by warriors on account of its protective qualities.
The hardness of a gemstone is measured based on a standard called the Mohs scale. The higher the Mohs scale number, the harder the stone is. Stones that have Mohs hardness less than 7 are highly subjective to scratching. Here are certain tips to keep your precious gemstone jewelry in good condition for a long time.
