Types of Diamond Grading Equipment

Here are the main types of diamond grading equipment:

Loupe: This magnification device can be used to determine features such as diamond clarity, dimensions, and inclusions. These are available as simple lens or with multiple lenses. Loupes availability in triplet or quadruplet lens system helps provide better focus and enhanced clarity..

Diamond Moissanite Testers: : To test the authenticity of your diamond, combine a moissanite tester with your traditional diamond tester. A diamond moissanite tester helps distinguish original diamonds from synthetic moissanites, which largely go unnoticed by traditional diamond testers.

Lamp: This convenient fluorescent lamp comes with a magnifier, tray, nipper and a box. This easy-to-use, portable light source with no predominant yellow or blue tint helps determine the diamond quality.

Electronic Diamond Testers: These testers use thermal conductivity to test diamonds. Different available models include direct AC current tester and testers with rechargeable batteries. Testers display test results through beeps and lights, making it the best testing aid for even a layperson.

Diamond Gauge: This equipment helps in determining the precise measurement of loose and mounted diamonds. This includes stone's cut quality, dimensions and carat weight.

Before grading, the surface of diamonds must be cleaned with a special cloth. You can also boil them in acid or wash them with alcohol. Avoid storing diamonds in anything that is not meant for the purpose. You can buy a specially crafted paper packet ideal for storing diamonds.

How Does Diamond Testing Equipment work?

How Does Diamond Testing Equipment work?

Diamonds have the highest thermal conductivity among precious and semi-precious stones, after synthetic moissanites. A diamond tester comprising a fine-tipped probe helps to determine the level of thermal conductivity. Diamond testers help differentiate diamonds from other simulants, which include CZ (Cubic Zirconia), YAG (Yttrium Aluminum Garnet) and GGG (Gadolinium Gallium Garnet).

However, this thermal conductivity testing device has certain limitations, as it fails to detect thermal inertia in some rare diamonds. This includes the Type IIb diamonds, which are semiconductors and blue diamonds (containing boron), such as the famous Hope Diamond. This results in the device registering these natural diamonds as fake diamonds. Moreover, since diamonds and moissanites have similar thermal conductivity, the device registers moissanites as real diamonds. Hence, using a thermal conductivity device alone could yield inaccurate results.

Hence, it is advisable to use other testing equipment to supplement the thermal conductivity test. This could include tests that measure the optical properties or electrical conductivity of stones.

Need for a Diamond Testing Equipment

Are you having a hard time distinguishing real diamonds from fake stones? No need to worry, as there is a wide range of diamond testing equipment available in the market. These equipments help in verifying the authenticity of diamonds, without one having to acquire any gemological education or experience. This makes diamond testing possible for practically everyone!

Need for a Diamond Testing Equipment

In today's competitive gemstone market, all professional jewelers must own a sophisticated range of diamond testing equipment. This is because traditional testing equipments are not equipped to deal with the growing issues of today, which include the most important need of distinguishing real diamonds from simulants. Simulants are fake or cultured diamonds that are artificially prepared in a laboratory. These resemble real diamonds in several aspects, making it difficult for a traditional tester to distinguish it from a real one.
