ブルートルマリン
Blue tourmaline refers to two rare varieties of tourmaline: Paraiba tourmaline and indicolite tourmaline. Pure blue tourmaline is incredibly rare, since most blue tourmaline gems have a green secondary hue. Paraiba tourmaline is considered to be the most valuable variety of tourmaline and was named after the source of its original discovery in Paraiba, Brazil. Paraiba tourmaline gets its neon blue-green color from traces of copper. Technically, the term 'indicolite' is used to describe any other form of blue tourmaline. Indicolite can range from light to deep-blue. Any blue tourmaline is considered to be very rare and anything weighing more than 1 carat is extremely rare. Tourmaline is both hard (7 to 7.5 on the Mohs scale) and durable, making it ideal for gemstone jewelry. It can be found in various cuts, shapes and sizes. Tourmaline is also October's birthstone.

Tourmaline is a stone that occurs in many different colors; almost every color of the rainbow. Another unique characteristic of tourmaline is that it can be electrically charged by changes in temperature or pressure. Tourmaline generally has a high level of clarity, has very few inclusions and is quite durable, with a hardness of 7-7.5 on the Mohs scale, all of which make tourmaline a very attractive buy. Large sizes are affordable as well. From this page, you can filter the results further by using the left-hand menu.

It's pretty great having a whole lot of different gemstones to choose from. When doing crafts and jewelry making, it's great to have all kinds of options, and it's amazing how much cheaper it is to just purchase un-set gemstones and make the setting yourself, as opposed to buying fully-made jewelry already. It's also extra special since you made it yourself.
