Art Deco Diamond Drop Earrings

Antique Edwardian late 1910s-early 1920s drop earrings. The top 0.1ct diamond suspends from a knife edge drop a further drop estimated to be 0.3cts. Total diamond weight 0.8cts. SI1/2. Set in 14ct white gold with new pins and back in 18ct (the UK does not stock 14ct gold, so I chose a higher gold ct for the new backs).
