Inclusions in Gemstones

In general, it is considered that transparent gemstones should be as clear and free from inclusions as possible. Inclusions are material that has become trapped in the crystal as it was formed. There are very, very few gems that contain no inclusions at all and there are some, again very few, who contain inclusions that make them incredibly interesting in their own right. In the short video clip here you see a quartz crystal that has formed with what is known in the gemmology world as a “Three Phase Inclusion” where you find a liquid filled cavity that also contains a gas bubble and a solid. In the video you can see that as the crystal is tilted to the side the gas bubble moves and the solid also moves in turn.
