Quality｜Citrine｜Taken from the "Angel Mine" in Mexico, La Aurora Mine, Charkas, San Luis Potosi, MEXICO. It is also the only mine that can be called mass-produced and has the highest quality among the few places where citrine is found. Citrine is not crystal, but a rare gemstone in its own style. Unfortunately, the name is too indecent, with both "citrine" and "gold", which causes Chinese people to reject and refuse to know this gemstone. In fact, citrine was originally named "citrine" because its hardness is the same as crystal, and its crystal structure is closer to topaz (scientific name is topaz), but the cleavage is unclear. Although citrine has a Mohs hardness of 7 to 7.5, which is lower than topaz, its overall strength and toughness are higher than crystal and topaz. Imagine if tourmaline was named after the homophony of "Tu Ma Lin", tourmaline would not be as popular as it is today. The naming of gemstones is very important. Topaz, almost 99% of Taiwanese people think it is a yellow stone, very similar to yellow jade, and is a Shoushan stone that was often used for seal carving in the past. But topaz is actually topaz, including blue topaz! Clarity｜FL [Flawless means flawless. This gem is called flawless because it refers to the GIA clarity standard for diamonds under 10x magnification.
