When the people demand more diverse when, jewelry design, innovative and varied and become the focus of attention. Fashion jewelry makes a woman releasing beautiful, beautiful and complex woman's pocket. Jewelry is the best choice. Jewelry is on the precious or semi-precious stones inlaid in precious metals, gorgeous sparkling, dazzling. This beauty or brilliant colors, or as transparent and clean, or with special optical effects.
Jewelry includes: natural jewelry and Jade (natural stone, natural stone, organic/natural stone)
Artificial stone (artificial stone, reconstituted stone, composite stones, synthetic stones)
There jewelry made with precious metals: gold, silver, Platinum, Palladium

4. organic gems
Natural organic gemstones: amber, Pearl, coral, ivory and other 4.
Jewelry fake mainly in material respects false, shoddy materials to imitate the real thing, among the high-end jewelry line. Jade and jewelry appraiser reminder:
Identification of Ruby
Natural stone "ten crack red nine", without any defect and cracking of natural Ruby is extremely rare. Synthetic Ruby color, defects or less crystalline inclusions, clean, large blocks. As precious gems on the market over 3 carats of natural Ruby is rare, and encounter a large block of Ruby, to attract attention, because natural Ruby correspondingly greater higher value than faux rubies and little oversight, "medicine".
Natural rubies have a strong "dichroic", the so-called Dichroic, that seen from a different direction, with shades of red and orange-red two, if there is only one color may be red spinel, Garnet or red glass.
Natural Ruby Red Spinel is very similar to the two most confusing, so it must be particularly careful.
Diamond appraisal diamond
The hardest substance in the stone is a natural material, diamond can scratch any other gem, but characterizations do not move any other gem diamonds. You can also use "standard hardness tester" score, where the degree of hardness is less than 9, it is a fake diamond. Diamond also has a lipophilic, such as pen, draw a line on the surface of diamond, in an unbroken line, while the other gems were intermittent discontinuity lines. These methods in identification of diamonds have a certain reference value. There are 10 times magnification observation, under 10 times magnification, most diamonds are visible defects, triangular growth patterns, diamonds on the surface of "red, Orange and blue" color "fire" light. Shooting out the lights. The most accurate method is to use "thermal conductivity meter" to measure thermal conductivity data to distinguish between true and false diamond, but the "thermal conductivity meter" is more expensive.
Identification of Sapphire
Natural blue color is often uneven, straight growth of most lines. Synthetic sapphire the same color, its growth patterns for the curved, often visible in vivo have bread crumb or beaded bubbles.
