For many jewelry makers, true artistic freedom begins where a diverse range of materials and high quality are reliably available – and this is precisely where A. Ruppenthal comes in. As one of the leading suppliers of gemstones and components, the company has shaped the craftsmanship of countless retailers, goldsmiths, and designers for decades, creating the foundation for individual jewelry ideas of exceptional breadth and depth.
If there's one stand at INHORGENTA where dealers, designers, and gemstone enthusiasts alike throng, it's A. Ruppenthal's. At approximately 320 square meters, it has been one of the largest and most visited presentation areas at the fair for years – a place where the entire spectrum of the gemstone world is showcased in impressive breadth and depth.
A traditional company with a European presence
Founded in Idar-Oberstein, one of the world's most historically important gemstone centers, A. Ruppenthal has developed over 135 years into one of the leading suppliers of colored gemstones, pearls, diamonds, and clasps. Its international focus is reflected in a closely knit distribution network: nine branches in major European cities such as Berlin, Hamburg, Antwerp, Zurich, and London, as well as eight traveling representatives who personally support retailers throughout the year.
In independent market studies, Ruppenthal is regularly chosen as one of the best suppliers in the fields of colored stones, diamonds and pearls – a testament to the trust placed in them by the heart of the industry.
A range that reflects the entire world of gemstones.
The ambition is high: visitors to Ruppenthal should be able to find the entire spectrum of gemstones. This ranges from affordable agate strands to rare treasures such as Padparadscha sapphires, Paraiba tourmalines, Mandarin or Mali garnets. In between, the selection unfolds a breadth that is virtually unparalleled in Europe.


In addition, there are diamonds in extraordinary cut shapes: Fancy Diamonds, rose and ball cuts, plate cuts and many other variations that open up new design possibilities.

Closing – a segment that Ruppenthal has redefined
Few other suppliers in Europe offer a comparable range of clasps. The portfolio ranges from simple silver models and classic gold clasps to high-quality versions set with diamonds and colored gemstones. This has made the company one of the largest clasp suppliers in Europe.
Currently in high demand are interchangeable clasps, which offer endless combination possibilities as a modular system, elegant, gold-plated versions and modern designs in silver and gold, as well as exclusive gemstone and diamond clasps.


The great strength: The clasps can be perfectly combined with strands of diamonds and gemstones – a complete concept that Ruppenthal has developed specifically for specialist retailers. This allows jewelers to create individual collections with clear differentiation, far removed from the mass-produced products of major brands.
Trends: Fine strands, faceted transparency, true diversity
Demand is currently shifting significantly: Given high gold prices, many retailers are focusing on stone necklaces and strands that require only a minimal amount of precious metal, yet still allow for high-quality designs. Ruppenthal is observing particularly strong demand for:
• fine, faceted gemstone necklaces in ruby, sapphire, emerald, tourmaline, aquamarine, tanzanite
• inexpensive Akoya cultured pearl necklaces
• Pom-poms, briolettes and drops in many types of gemstones.



These product ranges open up new possibilities for retailers who want to offer high-quality aesthetics without high material costs.
Advantage for specialist retailers: Selection without risk
A special service: Ruppenthal provides many of the most sought-after items in a selection upon request – a model that offers retailers maximum flexibility while minimizing economic risks. This is a significant advantage for retailers in times of volatile markets.
Why INHORGENTA is so important
For A. Ruppenthal, the trade fair is more than just an industry gathering. It's the place where retailers can see large parts of their product range live for the first time this year, compare them, and plan new concepts. No other event in Europe offers such a concentration of product range, quality, and variety – an argument that applies far beyond the company itself to the entire gemstone industry.
At INHORGENTA, Ruppenthal showcases not just stones, but an entire world of colors, shapes, materials, and craftsmanship. Anyone wanting to know where the market is headed, which varieties are in demand, and which combinations could become the next bestsellers will find answers here – expert, comprehensive, and always with the needs of the specialist trade in mind.
