Imitation Diamond Identification And Optimization Of Substandard Goods

With the development of science and technology can be used in place of Diamond More and more imitation, which includes natural and synthetic gemstones colorless gems, diamonds they imitate the effect of excellent, sometimes difficult to distinguish with the naked eye. At present, the optimization of the diamond are mainly two: low-light drilling and Glass Filling. They are mainly for the treatment of diamond clarity.

1. Laser drilling treatment: a laser to burn in diamond in a small body of direct channel package, package body can be laser burned; or after laser drilling a white body with acid bleaching. Treated glass or laser channels available Epoxy resin Sealed to prevent dirt into the channel. It can make dark inclusion shallow, so that the diamond has become well off.

This approach to diamond can be found under the magnifying glass 10 times the orifice and the holes by laser. Where drilling through the crown, when viewed from the pavilion side of the easier to see. After drilling the hole inlay may be covered up. Therefore, identification should be treated as such.

2. Glass filling treatment: the high refractive index glass fracture filling to have a diamond, making it seem the net degree of improvement, thus easier to sell. Its main object is to improve the diamond with open fractures, regardless of the size of the diamond can use the same method for processing. The glass used is similar to the refractive index lead glass diamond. After filling, fractured lower visibility, clarity improved, but it is not durable treatment effect: heat, acid or Ultrasonic wave Cleaning may be damaged. And the filling of the lead glass is sometimes yellow tone, will reduce the diamond's color grade.

Identification, we can reflect conditions observed in yellow and orange?? Purple or blue?? Green flash effect of the characteristics of interference, and the flat bubble and fractured.

In addition to diamonds imitation diamonds and optimized, there are stone floor together, often by means of such bogus people's negligence was unscrupulous traders, "succeed." The current mosaic in three ways:

1. Colorless synthetic sapphire + artificial joint in the strontium titanate. Synthetic sapphire strontium titanate of high hardness and strong color combination of fire, to the effect of imitation diamonds.

2. Diamond + synthetic colorless sapphire or Crystal . It uses a thin diamond crown diamond gloss and high hardness.

3. Small diamond + small diamonds, the synthesis of the two fight a whole.

4. Will be directly mounted to the thin metal on the diamond.

Observation method is not complicated stone mosaic, put together just to find out from the side surface, and find the diamonds, traces of glue on the joints can be sure it is put together stone.

Now have a synthetic diamond, synthetic diamond particles but small, and the cost is too high, yet the market volume, it will not cause confusion in the market.

Optimized diamond to diamond defects removed in order to improve the level of the diamond, but to enter the market, we have identified the appropriate way to handle the diamond has not optimized? Identification and Optimization of imitation diamonds sometimes substandard goods With advanced Apparatus To identify, below are three commonly used are:?

1. Thermal conductivity meter: it is based on the high thermal conductivity of diamond instrument design. Is the use of high thermal conductivity of diamond heat-sensitive components to quickly send out the heat transfer, the instrument lights up quickly, and issued purr. Thermal conductivity meter has a front-end Copper Probe, measurement, open instrument power supply, about 15 seconds after preheat indicator light work, this time, according to room temperature and measured the level of diamond size, according to an outstanding section of the back light device number, (the Japanese heat conductivity meter DIAMONDSELE CT OR) to probe thermal conductivity instrument rose contact with the diamond surface, a rapid increase in light equipment, and issued Chirping diamonds, natural gemstones and synthetic gemstones imitation diamond imitation diamonds (except synthetic Moissanite Sic outside) will not appear purr. It is suitable for rough diamonds, finished, not inlaid diamonds and diamond inlay. Even a small fraction of drilling. Identification is a powerful weapon distinction between imitation diamonds. ?

2. Moissanite (Synthetic silicon carbide Sic) determine the instrument: it is a designed to identify Moissanite (Sic) of the instrument. Diamond and Moissanite is based in the near UV of a different nature. Test Should be used in conjunction with the thermal conductivity meter. Because the thermal conductivity of Moissanite and diamonds similar instrument with a thermal conductivity can distinguish most of the simulation can not distinguish Moissanite diamonds. Therefore, we measured the thermal conductivity may be a gem diamond, there are some doubts may be Moissanite, the only instrument used to test Moissanite OK. ?

Moissanite determine if there is no instrument, there can also be used Moissanite birefringence phenomenon, and in polarized light microscope, light and dark appear to distinguish between changes and Diamonds. ?

3.X Radiography: X-rays can easily penetrate the C atoms, while imitation is absorbed X-ray. According to this theory, we use X-ray method can be distinguished according to Ningken both. A diamond, a gem imitations and tested on the photographic film, the X-ray irradiation, three different X-ray opacity may be recorded; diamond film exposed by X rays, absorption of X imitation Ray can not make film exposure. Developed film, the diamond will not imaging imitation image appeared, this method is suitable for diamond studded group Jewelry .

Appear on the market for fake products and optimize the processor, we already have scientific and accurate method of identification. Unique advantages of natural diamond imitation and optimization is always substandard goods can not match. In the coming days, there will be many "pretenders" to random people eyes and ears, confuse right and wrong. However, the fake is fake after all, they ultimately can not withstand serious examination. As long as we identify and gemology Expert Their tireless efforts, with the constant development of newer, more accurate out of the identification devices, and the careful observation and years of experience, will certainly "fake" detected, but also their true colors, so that they can not market based.

"A diamond is forever, stay forever in a mass" will forever change the mantra!

Round Cut Diamond

What properties could enable gold to be made into ring, copper into fine wire, diamond tocut glass,?

Heh. Looks like someone's class discovered Yahoo Answers all at the same time...I was PM'ed this question (among others) by another user over the weekend.

Ductility works for the wire. The ring requires malleability (literally latin for hammer-ability) to shape, or simply the ability to be melted at a lower temperature than your mold material. Diamond has crystalline structure that is stronger than most materials.
