Some Tourmalines contain tiny, parallel inclusions, causing them to display a strong chatoyancy and are cut en-cabochon to cats-eyes, which are rare- a collector’s gem. Tourmaline comes from the Singhalese (Sri Lankan) words ‘tura mali' – gem with several colors. Tourmalines come in a variety of colors, some have two or more colors, some even color-changing.
