Craftsmanship in the jewelry and gemstone sector always begins with a trained eye – and the right instruments. Whether a ruby reveals its true origin, a diamond possesses the expected clarity, or a colored gemstone exhibits unusual optical properties: without microscopic precision, much remains hidden. This is precisely where KRÜSS comes in – a company that has been providing the technical foundation for gemological quality work for decades.
A traditional company dedicated to precision
KRÜSS is a name that has enjoyed trust in professional circles for generations. Drawing on a long company history, the Hamburg-based family business develops and manufactures high-quality gemological instruments used worldwide in laboratories, workshops, universities, and studios. It combines classic optical expertise with modern technology, making precise analysis accessible to professionals and ambitious young gemologists alike.
What sets KRÜSS apart is the close integration of technology and application. Technical information, method descriptions, and practical instructions from certified mineralogists. Prof. Dr. Jochen Schlüter Many products are accompanied by documentation that helps users to professionally examine gemstones. This creates a knowledge base that extends far beyond the sale of equipment.
Instruments that enable craftsmanship
Gemological work is a delicate craft – and every detail counts. KRÜSS supports this work with precise measuring and testing equipment that reveals the key properties of a gemstone: cut, clarity, structure, optical behavior, and crystal type.
The portfolio includes, among other things:

- Refractometer, to determine authenticity and optical properties
- Polaroscopes, dichroscopes and spectroscopes, which make crystal structures and light behavior visible
- Stereomicroscopes, which reveal inclusions, growth lines and processing characteristics
- Magnifying glasses, tweezers and lighting units, which make everyday work in workshops and laboratories more precise
For many professionals, the microscope is the heart of their craft. KRÜSS offers up to... 5-year warranty – an indication of the company's technical longevity and understanding of quality.
Mobile working – as precise as in the laboratory

A special chapter of KRÜSS's DNA is its mobile gemstone laboratories: fully equipped suitcase systems that enable professional analysis even while traveling. This solution is unique for gemologists who work internationally or need to be flexible.
Battery operation, variable voltage supply, integrated lighting modes and a high-quality stereo microscope make the mobile laboratory a tool that brings precision to where it is needed – in studios, at trade fairs or directly at the dealer.
Innovations and technological advancements
At INHORGENTA, KRÜSS presents a new stereo gemstone microscope, developed to meet the highest demands. It combines ergonomic operation with state-of-the-art optics and variable illumination – a tool that demonstrates the close relationship between technology and craftsmanship.

In parallel, the company is increasingly focusing on digital knowledge transfer. In collaboration with a reputable gemology influencer, it is gaining access to a younger, inquisitive community interested in gemstones, laboratory work, and the professional application of equipment.

Craftsmanship requires knowledge – and tools that make it visible.
Craftsmanship in the gemstone industry is virtually impossible without reliable analysis. Designers and goldsmiths must know what they are working with: How does a stone behave in the light? What inclusions reveal its origin? Is a color natural or treated? What characteristics make it unique?
With its instruments and knowledge resources, KRÜSS creates precisely this foundation. The devices help to understand, evaluate, and safely process materials – thus supporting the entire value chain from raw material to finished piece of jewelry.
