New tumbled stones in 2025, 100% natural citrine from Madagascar.

Citrine, or lemon quartz, is the lemon yellow translucent variant of the mineral quartz (SiO₂). Properties Just like the other varieties of quartz, the translucent citrine is a nesosilicate. Trace elements, specifically divalent and trivalent iron, contribute to the yellow colour of the citrine. The crystal system of citrine is trigonal, and the hardness is 7. Name: Citrus is the source of the name citrine, owing to its yellow hue. Depending on the colour, the quartz variety was also called Madeira topaz, golden topaz or Bahía topaz in the past, completely incorrectly, because topaz is a entirely 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 burnt and sold as citrine. You can recognise this mineral by its brown to black points. Citrine is more valuable than amethyst.
