What is Essex or reverse crystal?
Mostly produced in the late 1800′s to early 1900′s. This is a technique where colorless transparent rock crystal quartz crystals are cut so that they are round, like a dome on one side and flat on the other, forming a cabochon. The flat side is carved or engraved and then hand painted with a thin layer of mother of pearl, giving the painted image a three-dimensional effect. This process is similar to intaglio jewellery and the artwork or paintings can be quite detailed and are sometimes signed by the artist.
