Distinguish appreciation

First of all, let us take a look at the main origin of the garnet:
Especially in Inner Mongolia, China garnet sand origin, Lianyungang, Jiangsu, Shandong Rizhao most representative. Inner Mongolia Garnet hardness, but the main wash wind, dust content, the impact of the cutting speed. In addition, for the production of small workshops, secluded inland transport costs are very high; Jiangsu Lianyungang garnet has been a major producer of domestic pomegranate sand, bright colors, hardness, open pit, mostly for local small workshop production, so the cost cheap, cheap, quality control is not strict, often have a variety of impurities, often plug waterjet.
The end of 2011, Lianyungang government closed the local mine, prohibit any person from indiscriminate indiscriminate open, leading to the domestic pomegranate sand supply is very tight; Shandong Rizhao garnet sand deep mine, the color crimson partial black, hardness, from 2011 began in the domestic market, is another lesser-known place of origin, the large amount of supply, stable quality, the maritime land are more convenient, the next few years a major producer of garnet sand.
Identify:
Garnet imitation goods very little. It is easy to distinguish. Distinguish garnet start from the following four points:
1, garnet color super-brilliant super-transparent, if the price is very attractive, work too hard, there is a problem.
See batt impurities, garnet inside easily with black spots, ice crack.
2, Garnet heavier than the average crystal, hold in your hands weigh lighter than the powder, you should be careful.
3, Garnet delicate, very slippery surface feel, feels very comfortable the oil feeling ~ and placed in the hands of a kind of cold feeling, soak into the depths of the heart, not powder "glass" feeling.
Ruby, red spinel and garnet similar gems. Ruby is a non-homogeneous body, dichroic, chromium characterized by absorption spectroscopy, fluorescence reaction, flat ribbon, needle-like inclusions into a 120 ° angle between; spinel low refractive index, fluorescence reaction, showing octahedral inclusions. Garnet as a homogeneous body, exactly the same color, Charles microscopic reaction, horsetail-like inclusions.
Quality water grossular was bright green, very similar to the Emerald. Water grossular often with black spots, a refractive index of 1.73, the red zone characteristic absorption.
Condition:
1, the color the more light the better (the garnet crystal born color than other heavy, light color hard to come by! Kind of a read talk to black, is the worst fineness).
2, as transparent as possible [any crystal.
3 Binglie as little as possible [any crystal.
4, based on the garnet Price from low to high is divided into three color: purple, rosy red, burgundy.
Favorites:
Current market selling crystal the image water tank crystal, gold hair crystal and the silver hair crystal, iridescent crystal, crystal animals and scenery Crystal. Jade collection area of ??investment compared to the purchase cost of the crystal is relatively low and relatively simple to identify, collections easier to start, to bring a lot of spiritual enjoyment as well as collectors, and sophisticated collection, but also can be achieved increasing the value of purposes. So why do some experts believe that Crystal does not have the value of the collection? Fact, experts said Crystal does not have the value of the collection should be ordinary popular and dependable crystal products.
"Crystal in the long process of the formation of absorption of many natural extracts, which also make the crystal is given to the many efficacy and purpose." Chinese Cultural Park Crystal Jade Shadow boss Zhao wood long introduction to say, quartz body (ie crystal) is the process of earth movement crustal plates press against each other and the high temperature diluted crystals experienced hundreds of years, thousands of years or even thousands of years, hundreds of millions of years after the formation of natural form, the beauty of nature left us. Therefore, the crystal as a non-renewable resources, with the continuous development will only become more and more scarce, the price rise is an inevitable trend.
