Learn about diamonds and how to identify real diamonds

Jewellery is lively market attractive in many parts of the world. Especially those gems is always a strong appeal for women

Of course, while indispensable, the presence of diamonds, was named king of the gemstones.

With the development of increasingly powerful technological, present, all kinds of synthetic diamonds (or similar stones) not only in the laboratory but also face overwhelming market jewelry. Artificial stone is increasingly manufactured with form and quality at par with natural stone and difficult to distinguish with the naked eye.

Under the name "artificial diamond" still hides many different issues. These rocks have similar properties is often based on how many people equate with shiny and diamond. This article will introduce you to some kind of "artificial diamond" and some tips Frequent reference to distinguish natural diamonds.

Diamonds are 1 in 2 allotrope of carbon has a very high hardness (10 on the Mohs scale) and the ability to refract light very well be applicable in many fields, from industrial to jewelry. Diamonds are for the mineral with excellent physical properties and are collecting rare gems like one.

1 diamonds are rated according to quality 4C: Carat (weight), Clarity (transparency), Color (color) and Cut (cut). Currently only 20% of the world's diamonds are used in jewelry. The rest of inferior quality are used in industrial and perform scientific research.

Until the mid-1950s, the only way to be able to own one right diamond is mined from natural deposits. Unfortunately, the process of formation of natural diamond requires temperature and pressure is very large (about 1200 degrees C and 5 gigapascal). The above conditions usually found at depths of 140 to 190 km below the Earth's crust. That's not to mention the time from 1 to 3.3 billion years to form and are only random pushed to the surface by tectonic forces.

The scarce supply of diamonds in 1953 led to the introduction of artificial diamond synthesized by two methods HPHT (high pressure - high temperature) and CVD (chemical vapor deposition). HPHT method is responsible for recreating the conditions deep underground. Meanwhile, the CVD method using the chemical vapor deposition of carbon compounds under the action of heat rays to separate plasma gas molecules to create the final product is carbon deposition, which grow up diamond seed. 2 methods are now being widely used to create diamonds in a lab.

The properties of diamond depends largely on the production process and production purposes. The synthetic diamonds are produced in the laboratory almost similar to natural diamonds. In fact, due to have been manufactured in a controlled and careful in the lab so even, artificial diamonds was hardness, thermal conductivity, electrical conductivity superior to natural diamonds . Moreover, diamond fabrication laboratory impurities is not mixed as some mining diamonds from the mine.

Therefore, in a certain aspect, both natural diamonds and diamond producer in the laboratory are true diamond (diamond truth). However, according to experts, the price of synthetic diamonds is very high, thus creating the same environment as natural to create diamond is extremely costly and expensive than extraction costs natural diamond. Therefore, synthetic diamonds are very rare appearance on the world jewelry market. The "diamonds" are usually advertised in the market is essentially mostly synthetic stone, usually stone Zirconia (CZ stones) or moissanite.

Standard 4C

Before the 1950s, the world has not yet held a professional and uniform criteria for assessing the value and quality of precious stones. Evaluation results can vary depending on where the evaluation. However, the Gemological Institute of America has ended this situation by 4C diamond evaluation standards common in the world today.

4C will Grading Standards 1 4 gems on physical characteristics: color, opacity, cutting and volume (carats).

Colour: 1 color of diamonds are rated on a scale from D to Z through comparison with those who have the best quality materials for use as reference. By the standards of GIA, grade D diamond is no color, transparent as 1 drop of pure water and of course have a higher value. However, grade Z will be tinted yellow or brown. Between DZ still some other level based on the color of the diamond pattern. In particular, Z grade diamonds are very rare yellowish color and high value.

Transparency: To be evaluated based on the result when viewed under a magnifying glass 10 times check amount of scratches, the color of the fracture, their locations, all of which are used to evaluate the diamond. All these factors are affecting the transparency and brilliance of the diamond.

Cut: There are many studies being studied mathematics to make the amount of light that it is the most reflective. One of them is the work of mathematician Marcel Tolkowsky mineral favorite. He had to think of ways to cut a circle and set the appropriate rate for it. A diamond is cut style modern circle on the surface have all 57 items. In particular, the upper surface and a bottom 33 with 24 present. The upper section is responsible for scattering light into different colors while the inside is responsible for reflecting light. This criterion will be assessed according to five levels of the elements of light reflection, light scattering of her ability to sparkle.

Carat weight: of course, the diamond gets bigger, the greater the weight the higher value. 1 unit is equivalent to 200 mg carats and can be divided into 100 points. 1 point is 1% or 2 mg carat is used to evaluate diamonds under 1 carat weight.

The following table shows the results evaluated by the GIA diamond made based on the 4Cs. Excluding employment fake paper, so to speak, if your diamond is certified, you absolutely can rest assured about the value of the diamond they own.
