G.F. Williams & Co. was founded in 1962 by Geoffrey Williams, who entered the gemstone trade in the early 1960s, working for a gemstone dealing company in London’s famous Hatton Garden. The 1960s saw significant growth in jewellery manufacture, with new production techniques requiring consistent sizes and qualities in large volumes. This, combined with close relationships with European gem cutting companies, helped develop the precision cutting of gemstones. It was this development within the gemstone industry that gave Geoffrey Williams the idea for G.F. Williams & Co., to source high quality gemstones for this new market.
Established in 1962, G.F. Williams has been trading for over 50 years and gone on to become a second generation family business. Now managed by Geoffrey’s son, Jason Williams, the G.F. Williams team remains committed to the supply of high quality gemstones, diamonds and pearls.
