Buyer's Guide: Diamond Tester

How Can a Diamond Tester Help Detect the Inclusions in My Diamond?

A diamond tester is basically a portable device utilized to test diamond material for their electrical and thermal conductivity as well as to check the clarity. It's quite an essential tool that's utilized by jewelry designers, dealers, and professional jewelers. It can safely indicate whether the diamond is an actual diamond depending mainly on the various gemological properties of the diamond.

A diamond tester is used when polishing a diamond so as to determine if it has a clarity which matches the owner's expectations. The tester utilizes two methods for performing this task; one utilizing a UV lamp and the other one employing a Microlight. If you wish to perform the test on your own then a UV lamp is the most suitable since it is easy to use and less expensive. This is also advisable to prevent you from damaging the stone. However, if you desire to test the stone with the highest levels of accuracy then a Microlight or Ionization chamber is the best results.

One of the primary uses of a diamond tester is to determine the color of the diamonds. Diamonds have different appearances depending on their levels of colorization. You will discover the difference in the coloration of good quality diamonds as well as those that have been heat treated. Some stones which have been enhanced with irradiation get a red hue whereas a stone that has been treated with a UVA lamp gets greenish shades.

You'll discover numerous models of diamond testers on the market today. A number of them are handheld which make usage of batteries to achieve the tester's results. This is essential whenever you're performing diamond testing on your own at home. Nonetheless, you'll discover that there are other models which are powered by electricity which is extremely convenient when you're conducting diamond testing on-site.

The most significant thing about diamond testers is that it can measure the level of clarity for diamonds. In order for you to determine the clarity of a particular stone you have to obtain a piece of diamond that is totally flawless. In cases such as this, you may use the level meter that is connected to the tester's probe. This enables you to determine the diamond's clarity level.

When using a diamond tester you should wear gloves and also be careful. You need to avoid getting any kind of puncture wounds from the needle-like tip of the device. The reason why you need to do this is because the heat generated by the device will cause the needle-like tip to bend. Once it bends it could easily inject you with heat which could possibly lead to various infections inside your hands.

Some people utilize diamond testers in order to detect the presence of inclusions in their natural diamonds. However, you should be aware of the fact that there are different types of inclusions that could exist in natural diamonds. Natural diamonds that are found in the vicinity of the geodes or at the base of the mountain are usually pure and contain no traces of inclusions. On the other hand synthetic diamonds that are created artificially are usually filled with tungsten filaments that could easily leave behind inclusions.

In cases where you have detected an inclusions in your natural diamond you should make the decision if it is really a diamond or not. To determine if it is a diamond consider using the electrical current that is associated with a real diamond. The difference between this type of testing and a diamond tester is that a diamond tester relies solely on the results obtained by the instrument. On the other hand a diamond examination relies only on scientific methods that are associated with the characteristics of real diamonds.
