Tourmaline cabochons are stones that have been cut into a
high domed round or oval shaped stone. Tourmaline cabochons are interesting gemstones
because they can show the multiple colors of Tourmaline by rotating the stone.
The best selection criteria for Tourmaline cabochons is much
like any other gemstone. First, try and select a stone that is very clean and
free from any inclusions. Tourmaline is a type II gemstone so this means that
most stones will have inclusions. However high quality jewelry grade Tourmaline
cabochons should be free from any inclusions.
In terms of color, Tourmaline cabochons come in just about
every color the rainbow has to offer. The dark green color is by far the most
common and least expensive color. Tourmaline cabochons really show off the
pleochroism effect that Tourmaline is famous for. If you rotate the stone you
will see multiple colors in different viewing directions.
Tourmaline cabochons are very durable as they are a hard
gemstone. However because a lot of Tourmaline cabochons contain inclusions,
these can act as a weak point in the stone. Tourmaline cabochons with inclusions
should be cared for more than stones without inclusions.
