Amsterdam Gems

I am a GIA-trained gemologist and professional jewellery expert based in Amsterdam, specialising in natural coloured stones, diamonds, and fine jewellery. Amsterdam Gems lots are carefully selected from trusted European and International suppliers and include untreated sapphires, rubies, and emeralds, as well as investment-grade diamonds and jewellery pieces. I focus on transparent descriptions, accurate grading, and full disclosure of treatments, and I am passionate about helping collectors find beautiful, well-documented stones with lasting value.
