This species has the largest variety of colors of any species known to man. The most popular color is green. “Rubellite,” which can easily be mistaken for a ruby, is extraordinarily beautiful.
Like other hues, it and its counterparts come in a variety of tones and intensities. “Indicolite” is a magnificent blue and can be confused with sapphire.
It is a very hard and durable stone and will wear better than many other gemstones. It doesn’t require any unusual care.
Some of the more unusual varieties are the parti-colors. “Watermelon” has been very popular, having a green exterior, a white intermediate layer and a red center. If the crystal is sliced “cross-grain,” it will appear to be a slice of “watermelon!”
Brazil is the primary source for most tourmaline. However, the San Diego area produces a sizeable quantity of very fine stones.
