wholesale silver jewelry supplies The efficacy and role of moonstone, how do you think of true and false?

great gatsby jewelry wholesale The editing of the identification method
The gems similar to moonstone are mainly white quartz cat eyes, chalcedony, white Ou, glass and plastic. Moonstone and their important

The difference between long stone
is:
1. Moonstone's faint is extremely special. Move, while quartz cat's eye moves the linear movement of eyeliner.
2. Long stone has obvious texture, and the different fractures can be seen at some tiny broken planes, while other similar gems are mostly shell -shaped fractures, and the fracture is smooth arc surface.
3. Sometimes the "hundred -footed" parcels can be seen inside the moonstone, which can be used as an important basis for identification.
Is when the above features are not obvious, they must be distinguished by determining the discount rate and proportion of the gemstone. Identify key typical explanation and characteristic parcels.
4. The blue of moonstone is very crystal clear, and the transparency of moonstone is also very high. The quality of the moonlight stones will be translucent, and the moonlight eye will be in the middle position.
Murard of the appraisal method of long stone is essentially based on the characteristics of the color, transparency, gloss, hardness, proportion, color scattered, discharge, fracture, dual refractive index, special optical effects such as parcels, colors, dispersion, discharge, fracture, fracture, fracture, fracture, dual refractive index, special optical effects, etc., and use simple tools Such as more than 10 times the magnifying glass, concentrated flashlight, etc. for identification.
It the color and transparency
The first thing to pay attention to is to observe the color of the gemstone. No matter what gemstone is, the scope of the appraisal is reduced with the different color and color of the gemstone

month long stone
. The special olive green color of olives makes us see it at first sight. A few gems are bright green greens, such as emeralds, emerans and some dye gems. The black gemstone is only Wu Gang stone, coal crystal, electrical stone, transparent pirate, and black rock. Purple gems include amethyst, amethyst, spinel, and cubic oxidation. When identifying emerald, Malaysian jade and green chalcedony, if you look closely, you can find that the green distribution of jadeite is uneven. , And sandy feeling, the color of the green chalcedony has milk -shaped feeling and evenly distributed. The color of the dyeing emerald is unnatural, and it is concentrated at the crack. The naked eye of ruby ​​and spinels is manifested in the ruby ​​with poly color. It is placed in the water. Sometimes the hexagonal ribbon can be seen, and the color of the red spinelite is absolutely uniform.
transparentness can be used to understand the advantages and disadvantages of gems. Generally speaking, the higher the transparency, the more precious the transparency. The transparency can also be used to distinguish the face

The monthly stones
are similar but different gems. For example, spinels are similar to purple tooth Wu in color, but spinels are transparent, and some purple tooth Wu is opaque or translucent. The same is true of yellow gems and sapphires. Yellow Heman is a transparent crystal, while sapphire is distinguished by transparent, translucent to opaque. Olives are transparent crystals, but some varieties are opaque.
The test hardness
The gloss of the gem is an important basis for the naked eye appraisal, which can roughly judge a satisfactory refraction range. The luster is determined by the level of refractive index and the degree of polishing surface. The stronger the luster of the gem, the higher the refractive index. The refractive index of the semi -diamond gloss gemstone falls on the high refractive index range on the scale of the refractor. The refractive index of gloss is a lower range. The waxy, glossy oil -luster jade polishing surface is poor, and the silk shiny indicates that there are many needle -shaped wraps in the gemstone. Amber with resin luster may be amber. It is carved into a curved type, translucent, cloudy, and the sky blue milky luster is ice long moonstone. The pearl luster is sodium long moonstone, and the blue gloss of yellow -brown luster is a long moonstone. The dazzling dazzling light in the sun is litstone. Diamonds have a typical diamond luster.
The gems with similar appearances, as long as they test their hardness, can be distinguished clearly. For example, diamonds, vermiculite, crystal, etc. Although the appearance is similar, the hardness is different. Diamonds can scratch vermiculite, crystal, but crystals cannot scratch the stones. For another example, ruby, red -tsioned spar, red tourmaline, purple tooth Wu, etc. are all red color gems. Knowing that they are different, they can be compared by engraving and distinguish them.
The hardness of the main gemstones is as follows: Diamond -10, Red and Sagua -9, Golden Cat Eye -8.5, spike -8, yellow gemstone -8, vermiculite -7.5-8, grandmother Green -7.5, tourmaline -7-7.5; Crystal -7, purple tooth Wu -6.5-7.5, olives -6.5-7, protein stones -5.5.
The use of hardness to distinguish gems requires the following points:
This has two limitations. One is that some colors of gems are similar in hardness, such as vermiculite and purple tooth Wu; the other is that it is powerless to artificial gemstones, because artificial gems are very similar to natural gems in physical properties.
This should not be too fierce during testing, especially not to knock on the schedules, but slowly drag.
It the proportion of the weighing and looking at the color scattered
It with your hand to estimate the proportion of the gemstone. It is a secret trick of an experienced appraiser. For example, diamonds and colorless artificial cubic oxidation

Monthly long stiff elegant pendants
The proportion of diamonds of the naked eye is 3.52, cubic oxidation proportion of 5.8, the same size of the noodles, one hand with one hand with one hand with a hand with one hand, one hand with a hand with one hand with a hand, one hand with a hand with one hand with a hand, one hand with a hand with a hand with a hand with a hand, a hand with a hand with a hand with a hand with your hands. Out, the light is diamond. Or the diameter of the eye -catching gemstone, you can roughly estimate the gravity and weight of the gemstone with your hands.
In the case of conditional permission, the proportion can be determined. The method is: the scales that are reused using the jewelry store on weekdays with jewelry stores. Hanging a small blue or bronze wire at one end, first put the gem into the basket in the basket to weigh, that is, the weight of the gem in the air. Then the small blue equipped with gem jewelry, the weighing weight of the rear scale immersed in water, the weight of the gemstone in the water. At this time, according to the principle of physics, the weight of the object in the water is equal to the object, which is equivalent to objects. The weight of the water of the same volume (but the water used is standardized by 15 ° C or 60F). Therefore, the formula is as follows:
The weight of the weight/weight in the air -the weight in the water
and then the corresponding gem name is found in the proportion table according to the proportion of the gem. There are a lot of gems, but it can also be combined with comprehensive analysis such as hardness and color to determine the name of the gemstone.
The more reliable method is the heavy liquid method, that is, the proportion solution with the same proportion of the gem to be measured, and then put the gem into the liquid to see if it is sinking or floating. For example, the proportion of emerald is 3.33, which is placed in a heavy solution of 3.2 grams per cubic centimeter. The jadeite will naturally sink because the proportion is greater than the weight liquid. Of course, it is not easy to formulate a certain ingredients for heavy liquid.
In transparent flip gemstones, color dispersion strength can provide important clues for identification. Only diamonds, artificial cubic oxidation, vermiculite, golden redstone, emeranex, tinstone, etc. can see obvious scattering with the naked eye.
Observing the parcel
The characteristics of the parcel in transparent gems with 10 times large mirror is the most reliable method to distinguish between natural and artificial products. The package of natural gems can be solid, liquid, and gas, and the solids are mostly crystal; mostly artificial gems have air bubbles, and rotor -shaped solid parcels are mixed objects for synthetic gems.
Itt the fracture and explanation
why the luster of the fracture and the surface of the fracture is particularly important for identifying some gems. Most of the gems with glass luster are shell -shaped fractures, and the translucent and opaque jade are mostly granular and different. For example, the fracture of the coral is no light and different outlets; the fracture of amber is resin luster, shell -shaped fracture; the broken parts of the chalcedony and agate are resin luster and shell -shaped fracture; green pine is dark oil luster, granular or shell -shaped fracture; The dense jade and Dongling stone are granular and different.
The dual refraction and multi -color
The double shadow at the edge of the transparent gemstone with 10 times the large mirror. This characteristic is also an important basis for identifying gems. Common gemstones with strong double shadows include vermiculite, olives, electrical stones, and golden red stones.

Mi -linked long stone diamond pendant
The dual -color of some color gems can be seen with the naked eye. The blue -green and brown -green duality of electrical stones, as well as ruby, sapphire, vermiculite, red pillar stones, stones, etc. As long as the gem is rotated, it can see obvious duality.
If depending on the special optical effect
The some gems have a special optical effect, and the emergence of any kind of optical phenomenon may reduce the predictive range of unknown gems. The top surface of the flip gemstone is facing down, placed on the white background, and the pen style is the bottom of the sample from different angles with a pen. Two -layer stone, pay attention to red, purple -red or thin samples. The red flash from the dark blue gemstone can be regarded as artificial spinel or Tanzania stone. Individual gems can produce color changes under different light sources. The stone is purple -blue under the natural light, and the tungsten light is red and purple. Bing long stone faint color changes in different light. Opal has a special colorful change. Snowflake -like flashing in sea blue gems. Common shore light gems include ruby, sapphire, hibiscus stone, and purple tooth. The four -shot starlight gemstone has spinels, pyroxyl, corner glitter, and if the gemstone is light and obvious, and the other is wide and blurred. In the magnifying glass, many seemingly metal parcels are transparent. Common cat eye gems include golden emerald, crystal, sea blue gems, electrical stones, long stones, etc. You are like tiger eye and eagle -eye.

wholesale jewelry medals For many years of jewelry appraisal experience, Moonstone belongs to the long stone family. Moonstone is divided into two types: ice -long stone and natalite. , Another moonstone is mainly white body blue light, called ice -long stone. Two kinds of moonstone are compared to the top of the white -body blue light, of course, there are also fakes on the market to fake the method of fake moonstone or coloring of artificial protein stones on the market.
