Collectors like the fashion collection of natural crystals, but often because of the market to see the face of a large number of synthetic crystals have missed it. In order to get value for money bed of roses to the natural crystal, china gemstone we can understand it from the purity synthetic crystals and natural crystals of three different details:
first, amethyst color group and color film. Amethyst in the synthesis, the often dark purple with good number of films directed, it is easy to think of natural amethyst in the characteristics of irregular flakes chromophore. The biggest difference between the two is the synthesis of deep purple amethyst in color groups were nearly parallel to the sheet orientation, size small difference of form, line clear. The color of natural amethyst group is arbitrary irregular shape, color changes with depth, but the line is the gradient. If we Synthetic Amethyst floating in the dark purple film metaphor of "purple cloth", then the natural purple amethyst in groups can be regarded as floating "Zi Yan group."
second, hexagonal ribbon and parallel to the ribbon. There is also a feature of natural amethyst, sapphire is the same as the hexagon with ribbon. The synthesis of the green crystal in color, usually with parallel ribbon, and one level along the wall parallel to the nuclear crystal growth. Crystal necklace with a synthetic green, yellow and green and white appear, much like the natural crystal ribbon, together with some brown translucent solid internal impurities, easily mistaken for a natural green crystal, jewelry supplier but the synthetic crystals formed along the crystal ribbon parallel distribution of the nuclear wall, made of crystal ribbon necklace changes the whole string line, the mere mention of each one of the ribbon the same width, giving a too much "in step" and not natural.
Third, inclusion, and cotton and crystal clear. In the natural crystal, the frequent inclusion and cotton, and synthetic crystal crystal clear, there are individual bubbles or solid impurities. Recently, some synthetic crystals are often a number of triangles within the long tubular holes in these pores in the green or red powder. This is characterized by a long tube along a direction parallel, triangular cross section, which often uneven green or red powder Yan Bi distribution, the middle is often empty, long tube headers have sharpened end of a trend. But the real natural crystal is contained actinolite, rutile and other minerals, crystals, these minerals have their crystal shape. Gemstone wholesale They are wrapped in crystal, the non-directional random arrangement of different thickness and length, and often accompanied by the inherent natural crystal inclusions and cotton and so on.

Pan Wen Chi Qiao know Jade
Pan Wen Chi is a common decoration on the Jade, and only a deep understanding of it, analysis can better identify jade and correctly judge the age of their production. Here to talk about the different periods of jade on the Pan Chi pattern characteristics.
Pan Wen Chi Warring States period, the characteristics of the head is round eyes, big nose, eye tail a little slender line. Double insignificant, china jewelry supplier the line is very shallow, very small, often difficult to see. Offline obvious, cat ears, most of the ears radius. Leg bend lines, claws are curved upward, curved lines with twists and turns, play to the joints are the main active Jiagu shown. Pan Chi body with decoration in general outline with Yin Xian, which drip shaped bend eggplant-shaped incised lines, is the initiative of the Warring States Period.

Short legs, front legs generally only one, behind the broad band can be said that the Pan Jin Chi pattern only three legs; broad thick tail, and other mammals is the case, this is the Six major characteristics of the times
Pan Chi Tang chevron pattern on the neck grain, ridges incised ridge began, and some joints in the legs, carved with decorative patterns like clouds, this decoration in the Six Dynasties Pan Chi has been there, china gemstone wholesaler after Tang Pan Chi also have, but the Six Dynasties and Tang Pan Chi moiré on only one hook, then some of the Cloud is more curly.
Pan Wen Chi Song nose has a very wide incised lines, mouth cocked like the same groove, mouth suddenly more, there has been three-dimensional. Hand-to-be little lips touched, it is Song Pan Chi Wen's main features.

Round the body engraved with Yinxian 1 or 2, stretch arm from the shoulders to represent the middle of spine and spine bounded by two single or double bend and then carve the wicker-like pattern to represent the ribs, the late Pan Chi ridge line both sides of the absence of such lines, but only a small number. Limb joints are decorated with paper moire, this is Chi Wen Yuan Pan the most significant sign. Also be cirrus-like tail, two stocks, one long, one short, so separate, tail specialty for whirlpool, longer than the previous periods.
Pan Wen Chi Ming Yuan shorter than the first type, facial features are mostly triggered by the central face, eye shape with circle eyes, triangle eyes, olive eyes oblique straight, long shoot eyes and shrimp eyes, etc., are enormous, with prominent eyes The shrimp eye the most.

How to select wishful crystal?
See choice of materials:
Selected well-crystal material, can not see stars punctate, cloudy and flocculent distribution of gas inclusions. Texture with pure, Guangrun, crystal clear as well, if there are different shades of off crack length, spot, then is defective.
To see work:
Process is divided into two kinds of crystal products, namely, grinding work and carving. Crystal necklace, bracelet, earrings and other items are grinding; view audio and video, such as inside painting snuff bottle is a sculpture. A good crystal should work fine, fine, not only crystal can fully show their beauty products (shape, style, symmetry, etc.), but also to explore its inner beauty as possible (such as crystal, skillfully color, etc.) .
See polished:
Polishing a direct impact on the crystal products worth. Crystal in the process to go through the process of diamond's polish and rough will produce signs of the friction surface of crystal. Good crystal transparency, better gloss than by jargon talk about "attempting foot."
See hole:
For the augmented through crystal products (such as necklaces, bracelets, prayer beads), depending on whether the hole straight, china jewelry if the thickness of hole symmetry, with or without small cracks. Hole must be clear, no "white marks."
See color:
Even in the same type of crystal in different parts of its texture, color is also great deal of diversity. Is monochromatic, to color evenly; in there with a piece of crystal depth, then the requirements of its beautiful natural color patterns.

Tips On Photographing Loose Gemstones
I find photographing loose gemstones to be an art form I may never fully conquer but I wanted to share a few tips I’ve learned over the years. My goal is not really to create an artistic photo of the gem but rather to depict the gemstone in the most accurate way. Lighting is by far more important than your camera setup but a few features on your camera are essential. A camera with manual mode that allows you to choose a custom white balance in Kelvin is a must as well as a good macro lens. I prefer using a focal length of 105mm macro lens so that I’m far enough from the gemstone to use my lighting setup. With this lens you can get about 6-8 inches away from the gem allowing for some flexibility.
I use two different lighting setups depending on what type of stone I’m shooting. I like to use the LED ring light from Table Top Studio for some gems and usually white balance around 6700K give or take. Even with proper white balancing though the LED lights will overemphasize the blue in gemstones. The LED setup works pretty well for green emeralds though. I also use a light tent with a couple daylight fluorescent bulbs that I white balance at around 5600K. For faceted gemstones I use a light on each side of the tent but if I’m shooting cabochons I use only one.
One mistake is to try to shoot gemstones pictures at your highest aperture setting. Often a really high depth of field will bring out too many details from the back of the gem and make it look much worse than with your naked eye. Try experimenting with a lower f-stop like f-11 or f-8 and see how it looks.

What Are The Different Types of Opals?
There are basically six distinct types of natural opal including black opal, crystal opal, white opal, fire opal, matrix opals, and boulder opal. The first four in this list are all solid opal while matrix opal and boulder opal have the host rock included. Boulder opals consist of a layer of opal that has formed in crevices of the host rock ironstone. When the stone is cut the host rock is left on the backside of the cabochon. This provides a dark background to the thin layer of solid opal. This is also left on for strength, as the thin layer of opal would be too weak on its own. Matrix opal is ironstone or clay stone in which the opal material has formed into the pores of the host rock. This type of opal is treated with a sugar solution and then acid to carbonize the sugar and create a dark background. Without this treatment the host rock appears brown and masks most of the play of color.
Black opal is solid opal that has a dark or black background tone, white opal has a light or white background tone, and crystal opal has a transparent background tone. Fire opal has an orange or red body tone and comes primarily from Mexico. Australia produces most of the high quality opal although various types can be found worldwide. Black opal is the most highly sought after type of opal followed by boulder opal, crystal opal, and fire opal. Matrix opal and White opal are the cheapest types of opal but still can reach hundreds of dollars per carat in their finest forms.

Best of Natural Crystal
In recent years, crystal jewelry popular in the jewelry market in terms of price, style, and features the kind of jewelry than other precious stones closer to people's lives. Then buy natural crystal jewelry, especially jewelry beading class time on how we can identify the authenticity of it?
Identification of natural crystal: I. Grossly texture
Pure natural crystal in texture, Guangrun, crystal is better, if there are different shades of off crack length, spot, then is defective. Remove the texture of very pure natural crystal, the general will contain even small stripes or floc, which is due to crystal formation in the natural course of naturally formed by the environmental impact. The man-made crystal is difficult within the general phenomenon of the above, but because of melting bubbles arising from the synthesis process, but certainly not within the natural crystal bubble.
Second, light intensity and the refractive index
Because of the high refractive index crystal itself, put the sun to see it from all angles, can send a beautiful luster, and glass jewelry will certainly not do. Besides, given the inherent "natural light", so the natural crystal and glass on the light dark places at the same time, you will find crystal light will be brighter.
In addition, because the crystal has birefringence characteristics, the crystal on the hair, the hair can be seen through a crystal is a two shadows.
Third, the temperature touch
Glass of warm compared to sense the temperature of the natural crystal is a very "cool" in. In addition to hand-touch experience, some people still willing to "lick the tongue", or crystal placed next to experience the alar cheek, because these parts of the body are very sensitive to temperature areas.
4, color
Crystal will be some natural color, this is normal. That showed a piece of crystal can not very uniform color for each part of. If a piece of crystal into the water, can be found in the water, the presentation of the color is uneven. But the general man-made crystal or imitation of the color more evenly. But because we buy the crystal has been cut most processed, so buy the best selection of monochrome color when the crystal is uniform, or the fine lines.
5, hardness
Crystal is a Mohs hardness of 7, although Mohs gap between the diamond 10, but still relatively hard crystals. Therefore, if found to significantly scratch the surface, there may be imitations, but depending on circumstances.
The main origin of natural crystal materials:
Relative to the diamond crystal is regarded as a high yield of gem, mineral distribution in the world is also more widely, the world's largest crystal origin and export to Brazil. Found that many people are willing to buy crystal at the same time as the way to inquire about the origin of crystal, the following I would like to share on the domestic market under the main origin of natural crystal.
Crystal according to the different species around the world, representative of origin, while the domestic market before the natural crystal material mainly from the East China Sea in Jiangsu Province, "the East China Sea Crystal." As China's "Crystal Town", the East China Sea crystal crystal production output accounts for two-thirds. As early as 200 years ago by Qing Emperor Kangxi repair, "Annals of Jiangnan" in it for the exploitation of the East China Sea Crystal had written: "Ushiyama, the sea state in the southwest Fatal strike, production crystals." In addition, there are major domestic producing crystal Yunnan, Xinjiang, Qinghai, Shanxi, Inner Mongolia. However, the crystal manufacturers from Brazil, Uruguay, South Africa, Russia and other countries imported crystal.
However be noted that in recent years has limited exploitation of the East China Sea crystal, crystal products are basically the market shipped from Brazil, the original stone factory processed by the East China Sea, that is the East China Sea has gradually evolved into our most processing to the main crystal.
In addition, because part of the crystal produced in the crystal is superior to Brazil, Uruguay, Crystal, but because of political, environmental, economic and other reasons, Paraguay has many mineral mines closed, so the origin of the crystal if the market price will very expensive, and most of the ore body is not new.
The Austrian crystal, in general, this is the Swarovski crystal artificial crystal, do not try to understand when the natural crystal.
Around the crystal have different characteristics, if you want to know more about some of the many to walk around the market, will be gradually mastered.
Tourmaline (Tourmaline), also known as tourmaline, tourmaline from the name to see the first use of the above for research. Although tourmaline used as decoration in the history of jewelry is not long, but now it has become a major jeweler's like to use things, and tourmaline in China also has an excellent consumer market.
Emerald (Emerald), originated in ancient Persian, "Zumurud", intended for the green stone. Turning to the famous Emerald, we naturally can not it be compared with our common beryl. The biggest difference lies in the long-wave ultraviolet light, no fluorescence could be presented by a weak orange-red to purple to red fluorescence, while most other beryl no such fluorescence.
Moonstones (MOONSTONE), is a moonlight effect feldspar group minerals from a mixture of two kinds of feldspar. Therefore decided to effect its beautiful moonlight. Moonstones quality mainly from Myanmar, Sri Lanka, in China there are moonstones output, and the texture is also very good.
Chalcedony, is a aphanitic quartz. The most common chalcedony main products are relatively low priced products, bracelets, often these can be bought at the jewelry shop.
Garnet (Garnet), said that from the Latin "Granatum" evolved, meaning "as a seed." However, natural garnet with pomegranate seed crystal is indeed the shape and color very similar. Garnet, also known as Purple Teeth Wu also called "Ziya Ukraine", according to legend its name from the ancient Arabic, "dental Ukraine", meaning "ruby." Because of the color dark red garnet with a purple gem so called "purple teeth Ukraine."
Identification of natural crystal: I. Grossly texture
Pure natural crystal in texture, Guangrun, crystal is better, if there are different shades of off crack length, spot, then is defective. Remove the texture of very pure natural crystal, the general will contain even small stripes or floc, which is due to crystal formation in the natural course of naturally formed by the environmental impact. The man-made crystal is difficult within the general phenomenon of the above, but because of melting bubbles arising from the synthesis process, but certainly not within the natural crystal bubble.
