Presidium is a world-leading manufacturer of digital gemological testing and measuring instruments. They are particularly known for their portable and easy-to-use tools that help jewelers and gemologists quickly measure dimensions, determine carat weight and identify gemstones based on their thermal and electrical conductivity.
Their digital tools are highly regarded for their speed, portability and clear LED displays that make them easy to use directly in the store or in the field. You can find the latest equipment at Riddgem, Presidium's authorized dealer in Sweden.
Presidium Instruments should not replace more in-depth gemological analysis. They work best as a first, complementary step in the identification process and can be verified with more advanced equipment if necessary.
NOTE! If there are requests for other Presidium products than those listed here. Use "contact us" and we will include your request when we bring new instruments from Presidium.
