We are Gaiety Gems, a family gemstone house in Idar-Oberstein. For twenty years, we have brought distinctive natural stones to the people who give them their next chapter.
Discover our story↗
Idar-Oberstein has cut and traded coloured stones for centuries. Its workshops, specialist knowledge and international connections make it a remarkable place to work with gemstones.
Gaiety Gems is a brand of AB Exim GmbH. We are gemstone dealers, working alongside the cutters this town is known for. We source, grade and sell from our home here, where every stone passes through our hands before reaching you.
Our founder built AB Exim GmbH one stone and one relationship at a time. Today, his two children work alongside him, bringing craftsmanship, design and a new generation of ideas to the business.
A founder’s eye for stones, and relationships built over years of buying and selling.
His son manufactures fine gold and diamond jewellery, connecting the material with the finished piece.
His daughter studied at Babson College in the United States. She leads our website, Etsy and eBay stores, and meets customers through selling and design at trade fairs.
From a stone ready for its setting to a strand ready for a designer’s hands. Each has its own colour, texture and possibilities.

Almost everything we list is an individual specimen, with its own weight, measurements and character. We want you to understand the stone before it becomes part of your work.
Our product photographs show the stone or parcel offered in that listing.
We describe weights, measurements, quantities and matched pairs in the listing.
We work with long-standing suppliers and share what we know about origin. Where provenance is uncertain, we say so.
We source worldwide and buy directly wherever we can. We keep documentation on the material we handle and welcome questions about a stone’s origin. Knowing our suppliers helps us understand their material; it does not mean every stone comes with a complete provenance record.
When you buy from us, you are buying from the people who built the business.
Colour changes with light. A stone’s flash reveals itself as it moves. If you are visiting the region or a fair we are attending, get in touch — we would love to put a tray in front of you.
