COUNTLESS UNIQUE ITEMS

Created over millions of years in the depths of the earth

GEMSTONES

For the creation of gemstones, our earth needs many millions of years.

For the most part, gemstones are found in regions that are difficult to access. People who are looking for such treasures are often exposed to the greatest dangers and hardships, in the hope of making a profitable discovery.

But if it happens every now and then that nature reveals one of its secrets, we should be aware of what we can hold or carry in our hands. In doing so, we will find out that every stone, present in a piece of jewellery or left as a mineral in its originality, is unique.

Santa Maria

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.

Spinel

Red Spinell · Pink Spinell · Blue Spinell

With a hardness of 8, the spinel is one of the hardest coloured gemstones. It occurs in different colour variants, of which the red spinel is the most valuable.

For a long time, the centre stone of the Imperial State Crown of the United Kingdom was thought to be a ruby. However, this is actually a spinel, which thanks to this finding came into the spotlight.

Tourmaline

Tourmaline

Paraiba · Rubellite · Mint Green Tourmaline · Green Tourmaline · Pink Tourmaline · Brown Tourmaline · Multicolour Tourmaline · Chromium Tourmaline

The group of tourmaline gemstones is characterised above all by its unique colour diversity.

Tourmalines occur in two – or even three – colour varieties and have a perfectly crystallized triangular shape which makes them very difficult to process. One of the most expensive versions, which has gained importance in recent years, is the Paraiba tourmaline from the Brazilian state of the same name.

The paraiba is one of the most expensive varieties from the tourmaline family and has gained in value in recent years due to its rarity

It is named after and originates from the state of Brazil of the same name. It owes its intensive colouring from mint green to bright neon blue, which is particularly sought after, to the trace element of copper.

Tanzanite

Tanzanite

Tanzania

A handful of gemstone lapidaries from Idar-Oberstein and the surrounding area, including Arnoldi, marketed tanzanite in the late 1960s to the New York jeweller Tiffany’s, which made the stone famous.

The unique, deep-blue tanzanite is only found in Tanzania and is characterised by its trichroism in its natural form.

Chrysoberyl

Chrysoberyl

Alexandrite · Cat Eye

The lesser known neon-coloured version of the chrysoberyl is a fascination by itself. The alexandrite changes colour: under natural light it shines green but under artificial light it shines red.

Despite its name, the chrysoberyl does not belong to the beryl group, and is characterised by its high hardness of 8.5. Its radiant brilliance makes it an instant eye-catcher.

Garnet

Garnet

Demantoid · Tsavorite · Mali Garnet · Mandarin Garnet · Rhodolite · Red Garnet · Hessonite · Spessartite

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 that introduced the Mandarin garnet to the market.
