Marcus McCallum

Marcus McCallum Ltd was established in London’s historical jewellery district of Hatton Garden in 1984. With a strong emphasis on quality, we offer a hand selected choice of one-off gemstones and an extensive selection of pearls. Marcus started in the trade due to a passion for gemstones and gemmology and over the years has built a team of gemmologists and experts in order to fully support the jewellery industry.
We take great pride in our hand-selected range of unique gemstones and extensive collection of pearls. Our stock is personally sourced from around the world and through regular trips to gemstone-producing regions, we have established strong global connections, allowing us to present you with a diverse and exceptional selection.
