emerald triplet

An assembled stone commonly consisting of a crown and pavilion of rock crystal bound together by transparent green cement or a thin piece of green sintered glass; immersed in water and viewed sideways, the top and bottom are colorless with a line of color along the girdle. Green or colorless beryl may be used for the crown and possibly for the 1081 pavilion. Glass may be used for the pavilion, and sometimes for the crown as well, but the trade still calls it an emerald triplet.
