Tweezers – Application & use
The intended use influences the choice of the shape of the forceps tip and the manufacturing material. But which tweezers are recommended for which areas of application?
All applications
Magnifying glasses – use and comparison
This handy precision instruments are used to analyze, measure, examine and for view controll.
Determine the place of orgin with microscopes
Along with diamonds, sapphires are among the most sought-after gemstones in the world. Their place of orgin is also important for determining the quality.
Distinguishing gemstones from glass
Polariscopes facilitate the rapid detection of common gemstone imitations, such as glasses or synthetic spinels.
Separate valuable rubies from spinels
The spinel is very often confounded with a ruby. The distinction is important because rubies have a much higher carat price in comparison.
Spot fakes with color filters
A look through a color filter lets some stones appear in a different color and helps to confirm an initial suspicion of forgeries.
Detect Synthetic Diamonds With Diamond Testing Instruments
Diamond testing devices are used to quickly and easily distinguish diamonds from other natural stones and imitations.
Testing gemstones with dichroscopes
Direction-dependent polychromy in gemstones can be examined with dichroscopes. In this way, for example, gemstone imitations can be identified.
Recognise false gemstones
By irradiating with a UV lamp, a large number of gemstones and ornamental stones can be checked simultaneously.
Inclusions microscopy
The observation of internal properties with special gemstone microscopes can be used to determine the quality and the place of orgin .
Determine gemstone type and quality
The refractive index can provide information about the quality and type of gemstone. Gemstone refractometers are part of the basic equipment for technical examinations.
