About Us


Welcome to T.L.Keith Diamonds

We are a family run business based in the Diamond Capital of England, Hatton Garden, London, with over fifty years experience in the diamond and fine jewellery trade.  Terry Keith started his career as a teenager in 1963, first as an apprentice in diamond cutting, then as a polisher and subsequently as a manager at L. Heilpern Ltd, the largest diamond cutting firm in the UK at that time. In 1977, Terry founded T.L. Keith Diamonds in Hatton Garden and still operates from the office in Diamond House on an appointment-only basis.
