TheGemGalleries is a platform for gemmology, jewellery design and guided educational tours.

As a Gemmologist FGA / DGA and business economist from Switzerland, I have 20 years of experience while living in Switzerland, China, Canada and Japan.

Since I relocated to Japan in 2018 I am offering jewellery and pearl tours in Tokyo. It is my passion to show tourists and anybody interested in pearls & gemstones around in the city and introduce them to hidden shops away from the main shopping streets.

TheGemGalleries offers tailor made services for private and corporate clients – these services include educational field trips, gemstone identification & appraisals, investment consultancy as well as business development for companies with an interest in Japan.

I look forward sharing my passion and knowledge with you. To get in touch, please send me a message to

Gemmologist FGA/DGA 


How it Started

I began my gemmology and design business in 2008 in China, sourcing the best quality freshwater cultured pearls for my clients and organising educational pearl workshops. I studied gemmology at the Gemmological Association of Great Britain and became certified after writing the exams in London, England. My interests in gemstones started during my early childhood. I grew up in Switzerland where I spent a lot of time up in the mountains, not only hiking but also digging for rock crystals. The sparkle of the stones and the various colours hidden behind the rocks fascinated me, and still do to this day.

Lucid Jewelry
