Because the cut gem-grade zircon is very similar to diamond, zircon is a natural gem with high dispersion value second only to diamond, and colorless and transparent zircon resembles diamond, so it is a good substitute for diamond. Zircon used to be called zircon.
② Swarovski (1895) was born in Austria and is famous for its advanced precision cutting technology and dazzling crystal products. Swarovski advocates the creative spirit, which is fully displayed in the series of accessories, jewelry and home accessories under the brand.
(3) So the Swarovski zircon you mentioned is a zircon product produced and sold by Swarovski.
(1) Swarovski:
Since the beginning of this century, Swarovski's crystal stone has been recognized as the embodiment of high quality, dazzling and high precision all over the world, which has laid the foundation for Swarovski's success. The charm of Swarovski comes from the quality of materials and the manufacturing methods adopted. As for the details of the unique method, it will not be disclosed to the public.
② The two main businesses of Swarovski enterprises are manufacturing and selling imitation crystal elements and designing and manufacturing finished products. Swarovski imitation crystal has become an essential element in international design works. Since 1965, the company has provided natural and artificial gem precision cutting for high-end jewelry industry.
Swarovski artificial crystal is famous for its purity, unique cutting and the arrangement and quantity of facets. In Wattens, a small town in western Austria, which is located in the remote foothills of the Alps and has a population of only a few thousand, thousands of tourists flock to see this grotesque alpine giant every day. The giant climbed a hill, and his big crystal eyes shone strangely in the sunlight. The fountain that rushed out of its mouth fell into the lake in front, making a huge roar.
This giant is the Swarovski Crystal World created by the crystal brand Swarovski on the occasion of the centenary birthday of 1995. Walking into the giant's mouth, the tourists' eyes suddenly opened up. In the20,000-square-foot visitor center, there are seven underground pavilions with different themes. The crystal works designed by those famous teachers are dazzling, but visitors often marvel at the world's largest crystal weighing 135 pounds, or linger on the crystal curtain wall composed of 12 tons of colored crystals. But when curious tourists ask to visit the crystal factory not far away, they will be politely refused by the staff. They will tell you that the production process of Swarovski crystals is a trade secret and is not open to the public. Indeed, although Swarovski generously showed people the most dazzling crystal products in the world, the crystal secret that has been carefully preserved for more than 100 years is hidden behind this brand.
(2) Zircon:
Zircon, also known as zircon, is called "hyacinth stone" in Japan. It is the birthstone of December, symbolizing success. (Birthday stones in December include turquoise and lapis lazuli) Its English name is zircon, which is one of the oldest minerals formed on the earth. Zircon is a mineral name, which used to be called zircon and hyacinthus orientalis, and transparent zircon gem. Its origin may have evolved on the basis of Arabic "Zarkun", which originally meant "cinnabar and Athena Chu"; On the other hand, it comes from the old Persian word "Zargun", which means "golden yellow". The first official use of "zircon" was in 1783 to describe green zircon crystals from Sri Lanka.
Zircon can be denatured after heat treatment. If the low-type zircon is heated to a certain degree, it will become a colorless and transparent crystal. For example, zircon in Sri Lanka is mostly green and low-type. After heat treatment, the color becomes obviously lighter and becomes a high-type zircon gem. Red and brown zircon produced in Hainan Province, China, can become colorless after heat treatment.
② Zircon is chemically stable, so it is often preserved and floated in sand, and appears in the form of detritus in sedimentary rocks and sedimentary metamorphic rocks. The zircon with real mining value is sand zircon deposit. Alkaline rocks and alkaline pegmatites are rich in comprehensive minerals, which are famous in southern Norway and Urals region of Russia. Zircon is also often enriched in placer.
③ The important gem-grade zircon in the world is produced in Laos, Cambodia, Myanmar, Thailand and other places. There are also gem-grade zircon in alkaline basalt in eastern China. Zircon is the most important mineral raw material for extracting zirconium and hafnium, and it is also used in national defense and aerospace industry.
④ The commonly used zircons are colorless, reddish brown, maroon and green. However, the most popular colors are blue and colorless, among which blue is of high value and is generally changed by optimizing heat treatment. Many zircon on the market are sold after heat treatment. Zircon is usually heat-treated to improve its quality or change its color or type. Because it has not added any other substances in the optimization process, it is still regarded as a natural gem in jewelry appraisal. After optimization, zircon will become more beautiful and more marketable.
⑤ Zircon contains radioactive elements uranium (U) and thorium (Th). But the content is very low, far below the safety factor. So you can wear zircon jewelry with confidence.
