Gemstones are so fascinating! Gems colors, properties, myths, and legends are diverse and fascinating. Folklore about stones has been revered and honored for centuries in all cultures.

What Is A Gemstone? A mineral or rock, after it has been cut and polished, and that is pretty and hard enough to be worn as jewelry, is called a gemstone. Only 70 of more than 3,800 known mineral s are considered gemstones. About 20 of these 70 gems are commonly found. All gemstones have one thing in common - beauty. Beauty, however, is a rather intangible thing. The perception of beauty varies from person to person, and from culture to culture. Beauty in a mineral may mean color, luster , transparency, or brilliancy resulting from skillful cutting and polishing.

Much of the gemstone history comes from archeological discoveries, and ancient writings. They are often found in burial sites where they were meant to protect and accompany their owner into the next life

Soft, opaque stones were the first gemstone beads. By 2,500 B.C. carnelian, lapis lazuli, and rock crystal were in use.

Colorful gemstones were first found on the earth's surface. There is evidence of gemstone mining of lapis lazuli in Afghanistan as early as 5,000 BC. In 3,000 BC, There was mining of turquoise in the Sinai peninsula and of emeralds in Egypt. Amber was traded in the areas around the Baltic Sea. In North and South America turquoise was mined.
