Reverse Intaglio is a rock crystal cabochon. A motif is carved into the flat back of the crystal. The motif is realistically painted in minute detail and is surrounded by a transparent ground. The deeper the carving, the more explicit the three-dimensional effect is when viewed through the top. This technique became popular in the mid 19th century, especially in England.
The name Essex Crystal is quite often wrongly used as a synonym for Reverse Intaglio. W. Essex was a well-known miniaturist in the 19th century.
