Amethyst is the most highly valued stone in the quartz group. The name
means ‘not drunken’, as amethyst was worn as an amulet against drunkenness. When
heated, Amethyst produces light yellow, red-brown, green, or colourless varieties.
Some stones lose their colour in daylight but can be restored via X-Ray
radiation.
