We grew up with the aquamarine, our signature gemstone.
The blue variety of the beryl group is distinguished by its high degree of hardness (7.5 to 8) and covers all blues, from glacier blue to deep sea blue. The most precious colouring is the famous deep blue Santa Maria, which gets its name through the mine of the same name in Ceará, Brazil.

Tourmaline Multicolor

Tourmaline Multicolor

The group of tourmaline gemstones is characterised above all by its unique colour diversity. Tourmalines occur in two or even three coloured varieties and have -perfectly crystallized- a trigonal structure which makes them very difficult to process.

Mandarin Garnet

Mandarin Garnet

The garnet is particularly impressive for its intense, strong and dark colours.
The high light refraction of the gemstone creates an extraordinary brilliance in all colour shades. Hubert Arnoldi was one of the pioneers who introduced the Mandarin garnet to the market.
