Citrine, amethyst and massive auralite per gram

Properties of rough quartz:

These massive rough fragments of amethyst, citrine, natural citrine and auralite present their particular characteristics. Each variety of quartz is valued for its inherent properties and its use in various disciplines. Natural citrine comes from Brazil and has not been subjected to heat treatment, showing shades ranging from lemon yellow to golden, with partial transparency and irregular texture surfaces. In contrast, heat-treated citrine is obtained from Brazilian amethyst and is distinguished by its golden and orange tones. Amethyst, also of Brazilian origin, exhibits a characteristic purple color with irregular surfaces. Finally, auralite-type amethyst, from Brazil, incorporates ferruginous inclusions and, in many cases, a distinctive reddish surface layer.
