Although the chalcedony is not as high as some precious rubies, the ornaments made of carnelian are still very good. The best carnelian is translucent, and some carnelian will be dyed. Carnelian is often man-made and often processed into beads, cabochons and engravings. So, how does the red chalcedony identify true and false? Please come and learn with the Xiaobian of China Jewelry Merchants Network .
True and false identification method of carnelian
1. Observation method: The red chalcedony is observed against the bright spot, and the color is transparent and the red is evenly distributed.
2, water identification method: a drop of water on the jade, if it is dew-like, long time is not true.
3, hand touch method: true red chalcedony, feel cold and lubricated by hand.
4, the tip of the tongue identification method: the tip of the tongue is really jade, but the fake red chalcedony is not.
How does the chalcedony distinguish true and false?
The red chalcedony is an orange to red translucent chalcedony in which the red color is caused by iron oxide impurities. Since carnelian is quite common, it is an inexpensive gemstone. The best carnelian is translucent and some carnelian will be dyed. Because the mineral contains Fe, the red chalcedony will appear brick red and unevenly distributed. It is visible to the naked eye that it is grease to glass luster, translucent to opaque, and chalcedony products can be distinguished according to differences in color, texture and density.
The formation of chalcedony is relatively difficult. It is generally known to occur in the sediments of hot springs and in the cavities of eruptive rocks, and it also requires a long-term objective environment of low temperature and low pressure. The conditions for formation are very harsh. Just look at its stalactite-like appearance and the fascinating colors filled with the spooky colors to imagine its rarity and preciousness.
The chalcedony is more dazzling after processing, crystal clear, especially the high temperature treated chalcedony halo, the color distribution is more uniform. It seems as if a drop of crystal water containing natural colors is in front of you.
In short, regardless of the natural value of carnelian or as a craft and jewelry, the beautiful appearance and precious value of carnelian are so touching, like the crystal of each center is summoning people's souls and purifying people. Mind.
