Quality｜Citrine｜The world's only purest source - La Aurora Mine, Charkas, San Luis Potosi, Mexico. This source is also the only known mine that produces high-purity slightly pink citrine. Citrine is not actually a "crystal" (quartz category), it is a class of its own. The mineral that is closest to citrine is topaz (topaz). Many chemical formulas of citrine are similar to topaz, but the Mohs hardness is only 7 (topaz is 8). However, due to the unclear cleavage of topaz, topaz is very resistant to collision. Therefore, even though its hardness is not as high as that of topaz, its overall wearing degree is slightly better than that of topaz, which is comfortable and safe to wear. In Europe and the United States, topaz has gradually become famous, and its price has far exceeded that of blue topaz.
