Susan Eisen's Gemological Laboratory Tools and Equipment include:
- Ultrasonic cleaner. Using vibrations that do not harm a piece of delicate jewelry, the ultrasonic cleaner eliminates dust, oils, and other contaminants from the surface of the jewelry.
- Electronic millimeter gauge. This gauge measures the size of a gemstone with precision accuracy in order to calculate its weight in carats; older, non-electronic gauges are not as accurate in determining measurements.
- Electronic gram scale. This scale measures a piece's weight in grams and penny weights to 1/100th of a gram in accuracy.
- Electronic carat scale. Today's precision scales provide a gemstone's carat weight to 1/100th of a point accuracy.
- Testing acids. Using a microscopic sample of a metal, various acids are used to determine gold authenticity and alloy content, ranging from 8K to 24K gold.
- Refractometer. This tool helps determine the refractive index number of a gemstone to help in determining whether a gemstone is natural or synthetic.
- Binocular 30x microscope. This kind of microscope uses two light sources to view a gemstone, identify inclusions, and help plot a gemstone's internal characteristics
- Camera. A good quality digital camera, such as a close-up camera with a macro lens, may capture the intricate details of a piece of jewelry or watch.
- Fluorescence machine. Under ultraviolet light, many gemstones emit different colors and levels of fluorescence, helping to identify the type of gemstone it is.
- Diamond dock light. This special light provides the proper lighting conditions for grading the color of diamonds and colored gemstones.
- Diamond Master Stones set. These GIA certified diamonds are used for comparison to determine diamond colors, from D to Z.
- Polariscope. This tool determines the optical properties of gemstones and whether they are singly or doubly refractive.
- Reference Library. The library at Susan Eisen Fine Jewelry and Watches includes more than 300 books on diamonds, colored gemstones, precious metals, goldsmithing, ivory, coins, jewelry manufacturing, jewelry trends, and many other subjects, in addition to up-to-date pricing guides, resources showing changes in the diamond industry and pricing, and other timely information.
