Identification of emerald from observation points: 1, viewing light: pseudo emerald and jade processing surface looks very clean, but the glossy surface of the light emitted thief, the reflected light is scattered, there is no sense of cohesion; and natural light emitted glossy emerald bright light, the light is together, very bright. This is because a high cohesion emerald crystals, crystal institutions has not been destroyed when the structure is very close, like a can not break the surface of the steel, the condenser; pseudo-natural jadeite jade is better because the structure of dense structure, treated by chemical etching emerald loose off the inside of the crystal cells, loosely gathered the optical surface can not, therefore astigmatism. 2, the internal crystal watch: natural emerald crystal structure are natural, translucent look inside, you can see the uneven distribution of the crystal surface, shiny; natural emerald marbled interior is not a round, but there are circumstances surrounding the stone root, balls of cotton body jade modern simulation, can be expressed as dispensing effect. 3, watch color: natural color regardless of the color of emerald color has its roots, the other is particularly difficult to distinguish a color of jade can watch translucent color, natural emerald color distribution thick with short, there are patches of colored root, natural color of the crystal is grown in the interior, following the trend of marbled distribution; inject color adrift, with no color, marbled colors can not follow the growth, so send virtual. 4, into the water: the emerald into the water, then let up, the surface of natural jade can unite many small droplets, the pseudo-jade and emerald can not be treated as drops of water, a piece attached to the surface of the stone. Discrimination principle and watch just the same. This method is the most easy to learn. 5. Feel: stroking emerald, emerald natural lubrication such as silk, jade and pseudo-treated emerald is not smooth to the touch, Sese feeling that this is a very subtle change, need more practice to achieve feel sensitive. 6. Taste: the emerald into the mouth, and no natural jadeite jade pseudo treated (ie, all kinds of crystal stone) there is no taste, cold lubrication true natural jade, jade can not have so pseudo-lubricated, treated Emerald issue some weird taste. 7, carving: very natural jade hardness, can be carved very difficult shape, carving detail is very fine, very smooth carving round natural jade, if you see a round yo emerald shape, to be sure natural jade. 8, fire: natural emerald after fire burned a little, there will not taste weird smell, and after cooling, the surface will gather some tiny drops of water; treated emerald will send some sour and so unknown gas, cooling After no water. 9, certificates, to obtain the corresponding gem identification certificate national certification is the safest way to identify any of fake and shoddy products in the precision of the instruments are no hiding place, named as (A) the goods on the certificate that is not dealt with natural jade.
