Following increasing demand, Sebex SA moved to Genova in 2018, to 17 rue Neuve-du-Molard. By relocating the company closer to a large base of its clientele, Sebex strives to effectively meet client needs within this constantly effervescent market, where the demand is as rich as it is varied. In order to consolidate this wish for efficiency, a partnership is formed in 2018 with Nicolas Emmenegger, a renowned lapidary from the Swiss market.



Sebex Pvt., Ltd. was founded in 2012 in Sri Lanka, followed by Sebex SA founded in 2014 in Switzerland. The latter business was based in the municipality of Lonay, in the Swiss canton of Vaud. These newly established companies were created with the aim of supplying clients with the most beautiful gemstones of the market, primarily intended for watchmaking.


SEBEX SA is a company with a large skillset formed by multiple synergies weaved together. This structure is composed of three entities situated at different strategical points within the market.

Geneva - Switzerland, where our sales office for the Swiss and International markets is located, as well as our workshop which offers a recutting service, assistance and advice.

Bangkok - Thailand, where the upstream stone sourcing is carried out by our main partner PETER & BROOKS (add link to website), with an office located in the heart of the gem hub.

Colombo - Sri Lanka, our factory is situated 20km away from the capital of Colombo, under the direction of Rasika, who manages the work of 34 employees including cutters, polishers and quality control. Every step of production takes place on our premises and follows a rigorous qualitative process.



The gemstones that we supply are aimed at the high jewellery trade, and principally at the watchmaking industry:

  • Round stones
  • Baguettes
  • Trapezes
  • Side stones
  • Central stones

Gemstones Expertise

Each of our cutters has their own set of skills, allowing us to obtain the best result once the stones have been re-cut. This process is supported by a diligent quality check done with a microscope between every step of the production chain.
We have the capacity to supply all types of gemstones including rubies, sapphires, emeralds, tourmalines, garnets and offer a large variety of ornamental and organic materials.
