Citrine crystal points.

Citrine or lemon quartz is the lemon yellow translucent variant of the mineral quartz (SiO2). Features Like other varieties of quartz, is a translucent citrine nesosilicaat. The yellow color is caused by trace elements, whereby in particular divalent and trivalent iron play a role. The crystal system of citrine istrigonaal and its hardness is 7. Name: The name citrine is derived from citrus (due to the yellow color). The fourth variety was, depending on the color, in the past also known as Madeira topaz, gold topaz or topaz Bahía called entirely unjustified since topaz is an entirely different mineral. Probably this happened to suggest a higher preciousness. Appearance: The main sites of citrine are Brazil, Madagascar and the former Soviet Union. Amethyst is often roasted and sold as citrine. This can be identified by brown to black spots. Citrine is more valuable than Amethyst.
