Cat Identification In recent years, the market has a glass cat's eye cabochon sales, set in gold or silver ring, make Zhenjiamobian. The identification method is that when the rotation ring faces, fake cat curved top can also occur with a few light, but really only one cat. Fake cat's eye liner rigid, while the real cat's eye liner and flexible sheets together. Real cat's eye color, mostly brown yellow or light green, false color cat's eye is diverse, red, blue, green and other colors. Chrysoberyl is second only to diamond hardness, red sapphire gem. And varieties of chrysoberyl alexandrite and cat's-eye, these three gemstones is not only very beautiful, and because of the extremely rare, so prices are very high. In chrysoberyl containing well-developed within the vacuum-like inclusions in chrysoberyl Kaposi Johnson cut imposed after the emergence of color change effect is opal.
Opal Identification Opal can be classified according to its color black opal, white opal, yellow opal, of which the highest price of the black opal. In order to lower the price of white or yellow opal improve grades, some discoloration on the use of artificial means to become "black opal" in order to reap Gregory. The main method is to cook with sugar or injection plastic, black to white opal. Identification method, after injection of Opal candied or the proportion of significantly different in the water test, the value of its lighter weight. Can also be tested with the heating of the needle injection opal, natural opal is not hot needle into the injection molding Opal to plunging, and will produce the smell after the molten plastic. Identification of tourmaline Tourmaline is a mid-range gems, but the pink and bright blue tourmaline more expensive, it also has to take the fake goods there. Common to take two types of imitation products, a class of colorless tourmaline artificial additive; a class of red glass processing. Identification method is really tourmaline often obvious dichroism, visible dual shadow; body visible tubular wrapper or cotton wool material, the crystal cross-section was triangular arc. These features do not have to take the fake goods, the workers stained tourmaline, color hanging as stagnation, lack of natural tourmaline "Glory", it is not difficult to identify. Crystal identification Crystal clear, often with cloudy, star spots or flocculent gas-liquid inclusions, and often have micro-cracks. In addition, the polarized nature of the natural crystal has seen double-crystal phenomena, such as a crystal ball body, looking down from above, met with a double shadow phenomenon. Synthetic crystal or glass, body, uniform clean, no cracks, often within a small bubble. Sphere from the top down view, see the following lines of double vision. Identify with the feeling can be felt is greater than the proportion of synthetic natural crystal crystal; a cold sense of the natural crystal, and glass with warm feeling. Identification of olivine Olivine is a green and yellow, similar to the middle and low olive stones, the market is the most common of peridot colored glass counterfeit goods. The main difference is that olivine has a significant "double vision", while the glass is not; often seen within the crystalline olivine inclusions, with only air bubbles within the glass; olivine proportion of 3.5, hardness of 7, compared with glass proportion (2.6) and hardness (6) to be large. Pearl Identification Pearls are natural pearls and cultured pearls of the points, there are water cultured pearls and freshwater pearl beads divided. Natural pearl production less expensive; and cultured pearls can be as large quantities of output, so the price is much lower. The main difference between the two is that natural pearls and cultured pearls there is no core. Natural pearls are often only some of the sand core or parasites and other things, not even nuclear. The cultured pearl of the kernel is the artificial production of large beads, so the outside of the parcel layer thinner. Reflected in the surface, the natural pearl is random because of the growth environment, nuclear small foreign body roll, poor roundness of its shape. Rounded cores cultured pearls, beads so good after the roundness. Because natural pearls grow for a long time, so beads after a fine texture, bead layer thick, smooth skin, very few "convex bubble", and more transparent. When cultured pearl beads due to the short sound, which bead thin, rough texture, luster with "wax" shape and the surface often has some bump "small bubble", transparency is also poor. If it is already perforated pearls with a magnifying glass to carefully observe the hole, and if so cultured pearls, beads in general can see there is a brown line, which is placed in the core and then grow out of the dividing line between the nacre.
