This tiny egg 3/4 inches (2 centimeters) high, is made of gold, and decorated with rose-cut diamonds, and guilloché and champlevé enamels in translucent blue, orange and green, and opaque white and black.
Champlevé is an enameling method in which decorations are carved into the surface of a metal object and filled with enamel (glass powder). After the enamel has been melted by fire and then cooled, the surface is polished. Since the colored stripes on this egg pendant is only 1/25 inches (1 millimeter) wide, you can understand how accomplished the egg's creator - head workmaster Erik Kollin - was.
The pendant was made around 1885, and now it's for sale again! So if you want it, take out 35,000 USD from your mattress, and follow this link to Romanov Russia!
