Tourmaline Stone Beads with the Cool Quotient

Tourmaline is a stone that is available in a range of colors much wider than any other gemstone. Therefore tourmaline beads are available in a lot of colors, qualities and shapes. Tourmaline beads are affordable and used widely in jewelry.

Like we said, tourmaline beads are available in a variety of colors. Most tourmaline occurs in various shades pink or green. But it also occurs in shades of red, brown, blue, yellow and black. Red to pink varieties of tourmaline are known in the trade as rubellite, black is known as schorl, green is sometimes known as verdelite, blue as indigolite or indicolite. However these names are used by traders and should not be confused with proper gemological names. The proper gemological name is tourmaline with the color prefix. For example: green tourmaline, pink tourmaline, black tourmaline etc. Black tourmaline or schorl is often used in mourning jewelry. Tourmaline beads can be either faceted or smooth. Not only beads, tourmaline is also cut as faceted stones and is often used in lieu of rubies (red tourmaline) and emeralds (green tourmaline) to bring down the cost of jewelry. This ensures that the jewelry remains authentic while at the same time the price is more pocket-friendly for the consumer.

Tourmaline beads are offered in various shapes. Tumbled beads have irregular shapes but a mirror smooth finish. Oval, cube, tubes, drops and faceted drops are some other shapes which tourmaline beads are available in. Tourmaline briolettes are often used in chandelier earrings. A briolette is a tear or drop shaped stones with tiny facets over it. Most often it is only partly drilled as it forms the dangling end of earrings or the fringe of necklaces.
