Some Beryls display chatoyancy and are cut en-cabochon to Cats-eyes, and are a collector’s gem. Beryl’s are beryllium-aluminium-silicates. As pure beryl, they are colourless, but coloration is derived from impurities - into green, yellow, pink or blue. Iron colours beryl into Blue- the most beautiful sea-blue Aquamarine. Traces of iron, and minerals containing uranium, give a colorless beryl an Intense yellow tone - the Golden beryl.
