[552] Andalusite
Andalusite is an unusual stone. It shows flashes of several different earth tones in the same stone. Because of its combination of colors, it has been called "poor man's alexandrite," but it does not look like alexandrite at all. Andalusite has very strong trichroism; if you examine the green stones carefully, you can see green running in one direction and a reddish brown color in the other direction. The third color, yellow, is difficult to see with out a dicroscope. Andalusite was named after Andalusia, Spain where it was first discovered. Today it is mined in Brazil and Sri Lanka..... (1999)

[553] Beryls - Aquamarine, Emerald and Morganite
Aquamarine was the talisman of the sailor for centuries, its colors resemble those of the sea and it has a delicate watery appearance that perfectly suits its name. It is the blue-green to green-blue variety of beryl. It ranges from an icy pale blue to a medium dark blue color. Although, even in the darkest shades, its color is always a pastel blue with varying amounts of green as a secondary color. Aquamarine can be found in fairly large sizes.

[554] Chrysoberyl - Alexandrite and Cat's eye
Ironically, chrysoberyl varieties include two of the world's most exotic and expensive gems, alexandrite and cat's-eye chrysoberyl, while yellow or yellowish-green faceted chrysoberyl is a nondescript variety in the low to moderate price range. Chrysoberyl is a tough and durable gem, which is rare even in its unappreciated faceted variety. Chrysoberyl, unqualified, refers to the yellow to greenish yellow transparent material. In spite of its good qualities, plain old yellow chrysoberyl is overshadowed by the spectacular charm of its siblings.... (1999)

[555] Cordierite: Iolite
You may never have heard of iolite. It isn't a household word, but it is an attractive indigo colored gemstone. It has been called a "water sapphire". Iolite is highly trichroic; in one direction it is totally colorless, this aspect was the origin of the water description. The "blue denim" gemstone is another deserving description. Iolite has a color with its own personality and deserves to be considered on its own merits rather than as a substitute for sapphires or tanzanites. Iolite is often used in jewelry with other colored gemstones such as amethyst, rhodolite, and pink tourmaline.... (1999)
