Established in Hatton Garden in 1984, Marcus McCallum specialises in supplying rare and one-off stones to the trade, along with an extensive stock of freshwater pearls and semi-precious beads.

If you are searching for a particular stone or simply seeking inspiration, then the team in our Hatton Garden showroom will be happy to discuss your particular requirements.
