We are a Swiss company specialized in the supply of high-quality coloured gemstones for prestigious watch and jewellery brands in Switzerland and throughout the world.

Understanding the needs and commercial requirements of the watchmaking industry, we offer customized solutions to meet the demands for precise cut gemstones, complex cuts and unusual/rare colours.

With direct access to mines and producers, an office in Bangkok and a close partnership with a high-tech factory in Sri Lanka, we conduct a strict monitoring from the purchase of rough to in-house heating and cutting processes. This structure enables us to guarantee complete reliability of our gemstones. 

Each partnership is a contract of trust we are committed to honour. We focus our efforts on satisfying our customers in all aspects, such as quality of cutting, purity, colour grading, delivery time, price and reactivity.

An ethical business approach, sustainability, traceability and preservation of our client’s identity reflect our key values.
