The so-called outside to see the seeds topaz is up a little better seed Qin yellow, jade not very good

Today, red, yellow, and Tianyu Cheng as the new darling of the market, where there is a market where there are fakes, and took Tian Huang Qin material, the dyeing of which there are many, and in 2004 appeared as the Huanglong, which has the Wada like topaz yellow jade, start “removed” and Tianhuang Yu in the market, it is hard to detect. The following will explain in detail the Tibetan Huanglong jade is posing and how Tianhuang Qin material.

Qin and Tian Huang

Many people want to collect seeds topaz, in fact, to tell you the true sense of the native seed topaz is actually non-existent, the reason is that, just as iron Qin color when pure interstitial lattice that will produce the kind replica Van Cleef Arpels of people like chestnut yellow or yellow chanterelles, if it is plain that the native lattice inside, the color must be yellow-green color, is the kind of material as yellow mouth yellow-green, the color does not look good. The so-called outside to see the seeds topaz is up a little better seed Qin yellow, jade not very good. But more of a slip stone, HuangLongYu like.

Huang Qin materials are seed material, color formation is a process of infiltration from outside to inside, from the late Qinru ferric ion dip coloration, because what we see is a yellow skin color Qinru more, even Qin full the entire material, the industry of the seed material floating on the surface of the skin color is called impregnation, the deeply ingrained seed material Qin Qin color is called material.

Talking about Topaz, a lot of friends will probably think of a similar name HuangLongYu. In fact, Huanglong is a quartzite quality jade, and nephrite Topaz and as completely not take sides. In mineralogy classification, Huanglong is Van Cleef and Arpels jewelry replicas a form of chalcedony, and later for the needs of the market, produced in Yunnan Baoshan Longling the yellow chalcedony named HuangLongYu.

HuangLongYu and many varieties of chalcedony not too clear on the distinction between the boundaries, so now on the market are many kinds of pipe colors are called Huanglong jade quartzite, not just yellow, but basically are yellow, red is positive the most expensive. Hot collection HuangLongYu originated in market speculation among consumers has not been a great audience.

In addition, posing as Huang Qin has a lot of material, kava stone, Horseshoe, Jade staining, dyeing serpentine rock and stiff seed staining, etc. on the market.

Kava stone (quartz) posing Huang Qin how to distinguish?

So how do we distinguish and Tianhuang Yu and HuangLongYu it? There are several ways:

And Tian Huangyu due to surface water infiltration of iron oxide fake Van Cleef Arpels jewelry yellow hue in the gap formed by the long-term. According chromaticity change named: dense sallow, chestnut yellow, okra yellow, yellow yellow, egg yolk and the like. Chroma thick dense sallow, yellow chestnut extremely rare, and HuangLongYu color except yellow and the red, white three colors.

And Tian Huangyu HuangLongYu and ingredients are not the same, and Tian Huangyu mainly tremolite mainly felt was like interleaved structure, mainly composed of silicon dioxide HuangLongYu muscovite, the main structure is massive structure, the Van Cleef and Arpels jewelry replicas strip structure, annular structure; Huanglong, compared to up relatively transparent.

Hetian Topaz hardness, 6.5, delicate texture, toughness, with a typical greasy luster, transparency is not high, but HuangLongYu hardness are higher than usual and Tian Huangyu to HuangLongYu hardness of 6.5-7, transparency Tian Huangyu ratio and high, both knockoff Van Cleef Arpels jewelry from the naked eye, and do not feel HuangLongYu Tianhuang Yu thick.

The relative density of 2.595-2.61 HuangLongYu, and the relative density of 2.90-3.10 Tianhuang Yu, the size of the same volume under Tianhuang Yu and heavier than HuangLongYu.

HuangLongYu speculation relatively large part, is quartz, which is a soft and nephrite jade. HuangLongYu material is quartz and chalcedony or quartzite, quartzite good texture can only be called quartzite jade. Because of widely distributed in nature, the price is not high, the collection be cautious. “Jade” in many different types, some value is not high, the Tibetan faithful need for vigilance.
