Blue Tourmaline Gems
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. By using the top menu, you can search by origin, carat weight, size, price and other factors, to enable you to find the exact tourmaline gemstones that you are looking for.

I love gemselect and I have bought a fair amount from them. The only complaint I have is not being able to save gems. I have a lot of projects so i am in the market for a lot of different gems and it's so disappointing to have to delete them all just to purchase one or two that I have saved in my cart.

Size and Weight

Gems are always measured in Millimeter (mm)

Dimensions are given as;
length x width x depth,
except for round stones which are;
diameter x depth

Select gems by size, not by weight!
Gem varieties vary in density, so carat weight is not a good indication of size

Note: 1ct = 0.2g
