They frequently asked questions
Microscopes and Loupes
High-power microscopes are used to examine internal and external characteristics of gemstones, including inclusions, surface blemishes, and cut quality. They provide magnifications typically ranging from 10x to 60x.
Spectrometers
These instruments analyze the light absorption and transmission properties of gemstones across ultraviolet, visible, and near-infrared wavelengths. This helps in identifying gemstone types and treatments
Laser Inscription Machines
These machines are used to inscribe unique identifiers or logos on diamonds and gemstones. Laser inscriptions can include a report number, branding, or security marks, aiding in traceability and authenticity verification.
Refractometers
Refractometers measure the refractive index of a gemstone, a key identifier for many minerals. The gemstone's refractive index helps gemologists determine its type and authenticity.
Polariscopes
Polariscopes help identify optical properties such as birefringence, which is crucial for distinguishing between different types of gemstones and identifying synthetic versus natural stones.
Diamond Colorimeters
These devices measure the color of diamonds precisely. Colorimeters can assess subtle variations in diamond color, which is critical for grading.
UV Lamps
Used to observe the fluorescence of gemstones, which can help in identifying certain types of stones and detecting treatments or enhancements.
Electronic Scales
High-precision electronic scales measure the weight of gemstones and jewelry with great accuracy, down to the milligram. Carat weight is a fundamental metric in gemstone valuation.
