Ball bracelet 10mm made of natural citrine from Brazil.

Citrine or lemon quartz is the lemon yellow translucent variant of the mineral quartz (SiO2). Properties Like other varieties of quartz, translucent citrine is a nesosilicate. The yellow color is caused by trace elements, in which divalent and trivalent iron mainly play a role. The crystal system of citrine is trigonal and the hardness is 7. Name: The name citrine is derived from citrus (because of its yellow color). Depending on the color, the quartz variety was also called Madeira topaz, golden topaz or Bahía topaz in the past, completely incorrectly because topaz is a completely different mineral. This was probably done to suggest a higher value. Occurrence: The most important sources of citrine are Brazil, Madagascar and the former Soviet Union. Amethyst is often burned and sold as Citrine. You can recognize this by brown to black points. Citrine is more valuable than Amethyst.
