My uncle and grandpa used to work at Engineering Diamonds when it was based in Warwick Row. Mum has been trying to remember where it was exactly and has a memory that it was in a cellar and somewhere near the Pepper Pot Cafe. If you looked down through a window, you could see the men working at the diamond cutting.
as a child, I used to think of them cutting big sparly diamonds for jewellery until grandpa told me that it was for cutting tools, I was very disappointed after that as it seemed so boring and ordinary.
Anyway, can anyone shed any light on the exact whereabouts of this workshop and when they moved?
