Extremely rare pair of hunting cufflinks in 18 ct. gold

An extremely rare and unusual reverse rock crystal intaglio 18 ct. gold cufflinks depicting a chamois, roebuck, deer and a fox. The reverse crystal intaglio started as a fashion in 1862 when the first example was shown at the international Exhibition in London. The underside of a smooth, domed piece of rock crystal was deeply carved and then painted in minute detail and backed with a slice of mother-of-pearl so that the subject slightly magnified by the dome of crystal, looked as if it was curiously suspended in its glassy cocoon.
