Friends the National Day is happy!
I also returned time of old home during holiday, because I am answered inaccessibly, a gang classmate that is close friends so gets together have a meal, sing.
Just a female classmate is wearing bracelet of a novice, call my side to look incidentally. Go soon really pretty good, kind, water, lubricious completely, the flesh appears ribbon of clear, whole bracelet to surround character, the good thing of 100 thousand above. But after taking close scrutiny washed-up, this bracelet lacks vitreous luster, some hair are frowsty, without glue feeling and fluorescent feeling; Take feel light on the hand, did not press the feeling of the hand; See color do not have lubricious root again, ; Next sound is more depressing, did not have ringing and bright, it is B+C goods certainly. What say I am bad at that time, if say,be fake, the face that loses her then.
The processing halcyon that basically appears on the market at present is B goods halcyon and B+C goods halcyon. So called " tall B " halcyon, imitate A goods halcyon to compare distinct emerald B goods or emerald B+C goods namely, because differ with natural halcyon very few, often by illegal businessman pass away the sham as the genuine, pretend to be emerald A goods to sell, seek sudden huge profits.
1, A goods halcyon: The emerald goods; that did not pass any artificial processing is natural halcyon, have maintain value and the value that collect;
Natural halcyon
2, B goods halcyon: Through corrode of strong acid dip, note glue or the emerald goods; of the processing that note candle again, hit candle is cleaned a few times disappeared, show crackle to come, the glue that note will be degenerative, do not have the function that keep a cost;
B goods halcyon
C goods halcyon: The emerald goods; that handles through artificial coloring, the color that catchs also is met first again green, blue, hind yellow, control 5 years commonly, color is met fade is smooth, do not have the function that keep a cost;
C goods halcyon
4, B+C goods halcyon: Through corrode of strong acid dip, again classics coloring and the emerald goods of the processing that note glue, internal composition sufferred destroy, halcyon besides decorating a gender, already did not have the function that keep a cost;
Goods of B of emerald finished product, C, its characteristic is very transparent, what feeling and glass of natural A goods are planted or put kind of halcyon on the ice to agree is clear and fruity, burnish is very good also, brighter, and meeting occurrence interior is returned to glance in transparent place, call commonly case " fluorescent " . Actually, although goods of this kind of halcyon is in the respect such as diaphaneity, burnish and emerald A goods are very similar, but differentiating a feature still is more apparent, main from the following respects:
1, look " fluorescence " : Transparent halcyon is in because dambered surface place gets together smooth effect, can appear brighter, common says to rise " fluorescent " . Of halcyon of natural A goods " fluorescent " for white, more natural; And " tall B halcyon " what remove " fluorescent " often be La Bai color or blue purple is extremely factitious, both Bao is shown different.
2, view: See a structure nearly coarse, naked eye can have seen the acid etching grain of exterior bumpy, the structure of acid etching grain that naked eye can have seen exterior bumpy very medicinal powder, after passing acid treatment, note glue again, because this cannot see halcyon is mineral structure, and look very ambiguous very adhesion.
3, hear voice: Sound of knock of bracelet of halcyon of natural A goods is like metallic sound, ringing and bright, have echo; and " tall B halcyon " bracelet knock sound is depressing and dull, without echo.
4, feel: Blow halcyon with fingernail, halcyon of natural A goods is smoother, fingernail feeling is less than any obstruction, smoother; " tall B " halcyon can feel fingernail sends , not quite smooth
And goods of Gao Cui B, its feature is to have natural emerald color, but passed strong acid dip corrode and the processing that note glue. The former unripe wollens of this halcyon often a copy kept as a record is greyer, have a few motley with foreign matter be contaminated, motley existence masked natural green, after passing corrode of strong acid dip, gloomy motley can be immersed eliminate, make the green that is born formerly can be shown come. Because this halcyon was to pass corrode of strong acid dip and the procedure that note glue, what although existence has,be born formerly is emerald, but the value that has done not have natural halcyon. ,
Because the green of goods of Gao Cui B is former unripe green, also have the expressional feature of lubricious root, this and A goods halcyon are very similar, in differentiate a respect to need to notice:
Goods of Gao Cui B
1, see through lightness: To natural halcyon a cant says " dragon has water everywhere " , because the green in halcyon often shows belt shape to appear, like liking one continuous line. "Dragon has water everywhere " it is to show green place often is compared transparent, white place can be differred relative to diaphaneity a few (graph 9) , reflected A goods halcyon to be in the inhomogenous sex of diaphaneity of different color place; Halcyon of goods of Gao Cui B is different, because passed strong acid dip,corrode is mixed the processing that note glue, the place with original opaque white, often can become more transparent, and white place and green ministry diaphaneity are consistent (graph 10) ;
Natural halcyon
2, see white rate: Place of white of A goods halcyon often is compared white, and place of white of halcyon of goods of B of inhomogenous; Gao Cui is not quite white, slant instead grey, show oily, and tonal agree equably everywhere (graph 11);
C goods halcyon
3, see green bright-coloured degree: Green of A goods halcyon often appears dark, color shade is inhomogenous; And green of halcyon of goods of Gao Cui B is relatively bright-coloured, color takes yellow taste slightly, color tends consistent, appear more inflexible;
Still be less than as a result of the compasses plasticity of gem market, good and evil people mixed up, cheat technology is more and more brillant also, let people's air defense be prevented deeply. As consumer for, what should remind is: Emerald jade or gem jewelry are bought on any markets, must buy to the brand store that has reputation or bazaar, the gem calibration certificate that and should have orgnaization of quality inspection authority issues or quality inspection certificate, if quality of national jewelry jade is supervised,examine headgear of supervisory gem of quality of city of center, each province examines the center waits; a moment additional, before buy, have a few knowledge to knowledge of relevant gem headgear, the friend that there had better be know the business when buy is attendant and directive. Because buy gem jade, buy a mood for oneself namely actually, try to win sb's favor find the scenery pleasing to both the eye and the mind, buy a fault sad.
