The Graff Jewellery Store in Knightsbridge, London that was used as Charles Hodgson's place or work was itself robbed of £1.4m worth of jewels on 11 September 1980. The robbers' haul included the Marlborough Diamond, then valued at £400,000.
Robert Shaw's wife, the actress Mary Ure, died during the making of this movie.
Promotional artwork for the film formed the letter ''O'' in the title logo of the movie's ''DIAMONDS" name with an animated drawing of a diamond.
The movie's closing credits declare that this picture was: "Shot on location in Jerusalem & Tel Aviv, Israel and London, England."
This movie called ''Diamonds'' was also released as ''Diamond Shaft'' in some English language speaking markets and territories despite the fact it bore no relation to the then popular ''Shaft'' feature film franchise of which second billed actor Richard Roundtree was its star.
