Gemstone few as one in a million atoms. These so-called impurities are sufficient to absorb certain colors and leave the other colors unaffected. For example, beryl, which is colorless in its pure mineral form, becomes emerald with chromium impurities. If manganese is added instead of chromium, beryl becomes pink morganite. With iron, it becomes aquamarine. Some gemstone treatments make use of the fact that these impurities can be "manipulated", thus changing the color of the gem. Gemstones are often treated to enhance the color or clarity of the stone. Depending on the type and extent of treatment, they can affect the
Gemstone (database) was a software engineering manager from Electro Scientific Industries, and Monty Williams. Servio Logic was renamed GemStone Systems, Inc., in June 1995. The firm developed its first hardware prototype in 1982, and shipped its first software product (GemStone 1.0) in 1986. The engineering group resides in Beaverton, Oregon. Three of the original cofounding engineers, Bob Bretl, Allen Otis, and Monty Williams (now retired), have been with the firm since its start. GemStone's owners pioneered implementing distributed computing in business systems. Many information system features now associated with Java EE were implemented earlier in GemStone. GemStone and VisualWave were an early
