The difference between yellow dragon jade and topaz

Huanglong jade, also known as dragon topaz, is a new kind of jade discovered in Longling, Yunnan Province in 2004. Topaz is a fluorinated silicoaluminate mineral, also known as Huangjing, which is formed by steam discharged from igneous rocks in the crystallization process and generally occurs in the holes of rhyolite and granite. let's take a look at the difference between Topaz and Topaz.

The difference of composition between Huanglongyu and Topaz

1. Huanglong jade: the main composition of Huanglong jade is silicon dioxide Muscovite, and it also contains metal elements such as iron, aluminum, manganese and more than 40 kinds of trace elements, but it is not a single crystal, but a polycrystalline complex similar to jadeite and Hotan jade. the hardness is the same as jadeite, the motorcycle hardness is 6.5 to 7, the toughness is better than jadeite, slightly lower than Hetian jade.

2. Topaz: topaz is a general gem, which is composed of fluorinated silicate with a hardness of 8. The common colors are colorless, pink, yellow and blue. The common gemstones that are easy to mix with topaz are crystal, aquamarine, tourmaline and glass imitation, among which yellow crystal is the most easily confused.

The difference of producing area between Huanglongyu and Topaz

1. Huanglongyu: Huanglongyu is a new kind of jade discovered in Longling, Yunnan Province in 2004. Excellent gem-grade Huanglongyu is mainly produced in Xiaoheishan Nature Reserve of Longling County, Baoshan City, Yunnan Province and the surrounding Supa River Basin. It is very close to the jadeite producing area of Myanmar and belongs to the Dianbao Burmese jade metallogenic belt formed by the mutual extrusion of the Eurasian plate and the Indian Ocean plate. Here, the original forest coverage is very high, the topography is complex, the climate is diverse, and Rain Water is very rich, which is known as the rain screen in western Yunnan, which provides very unique and irreproducible natural conditions for the formation of excellent jade.

2. Topaz: Topaz is a typical gas hydrothermal mineral, which occurs in the crystal cavities of granite pegmatite, acid volcanic rock, quartzite and high temperature hydrothermal tungsten-tin quartz vein. Topaz is produced all over the world. China is mainly produced in Inner Mongolia, Jiangxi, *, Guangdong, Yunnan and so on.

The color difference between Huanglongyu and topaz

1. Huanglongyu: the colors of Huanglongyu are light yellow, golden yellow, orange red, orange red, pigeon blood red, light red, golden orange red and so on. These tones are the most active, prosperous, honorable and auspicious colors in warm tones, which are the first element of Huanglongyu's popularity and value.

2. Topaz: topaz is generally columnar or irregular granule or block, with a variety of colors, such as yellow, blue, green, red, brown and other light colors, with glass luster, some colorless and transparent, and the color will fade when exposed to the sun for a long time.

The value difference between Huanglongyu and Topaz

1. Huanglong jade has the warmth and moist of Hetian jade, the color of Tianhuang, the hardness of jadeite, the flexibility of Shoushan stone, the fibrous structure of jadeite, the radish pattern similar to Tianhuang, the satisfactory "water head" of jadeite, and a better "oil head" than Hetian jade. its glass luster is more attractive, plus the main color of Huanglong jade is yellow and red, which means "rich". Red means "auspicious", not only can play with the original stone, but also suitable for carving into a variety of furnishings, accessories, favored by consumers, has become an upstart in today's jade collection.

2. Topaz: before being developed as a jade, topaz was only collected and bought and sold as an ornamental stone, and was called "yellow wax stone". Because of its fine stone, golden color, large block size, rich variety, and high ornamental value, it has reached thousands or even tens of thousands of yuan per kilogram, and its price has risen rapidly, creating a miracle in the history of jade. in fact, not all topaz can be regarded as topaz. Only the yellow wax stone that reaches the jade grade is called "topaz".
