What is a Gemstone?

When you think of gems, you most likely envision lavish and expensive jewelry, however, a gemstone isn’t limited to a priceless pair of diamond earrings. A gemstone has many names which include: gem, fine gem, jewel, precious stone or semi-precious stone. When a piece of mineral crystal is cut and polished, this is when it goes from a glorified rock to become a gorgeous gemstone. Rarity is an important characteristic when dealing with gemstones because the more demanding and difficult it is to find, cut, and polish the gem, the greater the value of the gemstone grows to become.

What is the Value of the Gem Encyclopedia?

The GIA  is a world leader in gemological research through education, impartial gem grading, and analysis. In 1931 Robert M. Shipley created GIA and opened the very first United States based gemology correspondence course. Eventually, this lead to the professional designation of becoming a certified gemologist. If you want to compare, browse, or learn more about any gemstones like diamonds, colored stones, or pearls, the GIA is the paramount informant on gems and jewelry.
