men’s bracelets the red, blue and green of chalcedony

From the delicate apple green to the green chalcedony, it is called green chalcedony. It is the most valuable kind of chalcedony. Its English name chrysoprase is derived from the Greek, referring to the leek, which is named for its green color.

Chrysoprase is green because of its nickel content. Its appearance is similar to that of jade, making it a common substitute for jade; and because Australia is an important source of green chalcedony, it is also called commercially. “Australian jade”, the difference between the two is easy to distinguish. The easiest way to distinguish is the specific gravity liquid. In the diiodomethane liquid with a specific gravity of 3.32, the specific gravity of jadeite will sink at 3.34, but the specific gravity of chalcedony will be lower than 2.60-2.68. The specific gravity fluid will float; of course, experienced consumers and gem appraisers can distinguish between the two gems based on the difference in their structure.

A few years ago, a kind of sky blue gemstone called Taiwan Sapphire was popular in Taiwan, which is blue chalcedony. Some people call blue chalcedony chrysocolla. It is blue because it contains copper and Cu in malachite, but it itself The component is the silica of chalcedony, so it is called Chrysocolla. Tidligere, because the quality of blue chalcedony produced on the east coast of Taiwan was the highest in the world, and Taiwan’s efforts to promote local jade, not only did this blue chalcedony be called Taiwan Sapphire, it also held a place in the international market. For a while, the price of blue chalcedony remained high, and the value was almost equal to that of precious red sapphires.
