The Jewel is not recorded in the Campbell Dodgson's A Catalogue of Etchings and Engravings by Robert Austin, R.E 1913-1929 and therefore might never have been editioned. Austin's original etching plates were rediscovered in 2007. They represents all aspects of the artists oeuvre, from his first engraving (The Bridge, 1913 ) to his his last (Frost in May 1971). Although, as was common practise amongst print makers, Austin cancelled his plates after their edition run, the manner in which he did this is remarkable. Far from defacing the compositions by scratching lines across the centre, or drilling holes in the plates, Austin drew precise lines of different proportions, dissecting each composition, responding individually to each image. As such the geometry of each composition appears heightened, and the plates take on a abstract beauty of their own.
It is generally acknowledged that Austin was one of the greatest exponents of line engraving of the Twentieth century. Campbell Dodgson, keeper of Prints and Drawings at the British Museum, who compiled the standard reference work on Austins' work, compared his work to that of Durer noting that Austin had 'more than a touch of that master in him' (Robert Austin, Twenty-One, 1930 Gallery).
Austin's period of greatest acclaim was during the etching boom of the 1920s (which ended abruptly with the Wall Street Crash). Later works however, (for instance Girl by a gate,1930 and Empty Church, Concarneau, 1949,) demonstrate that Austin was still at the height of his powers long after his period of greatest acclaim.
