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. 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. So, if you are looking for a diamond testing equipment to meet your needs, look no further. Log on to www.igem.com to select from a wide range of state-of-the-art diamond testing equipment. Our range also includes equipments that incorporate two devices in one, which in turn, help in yielding more accurate results.
