Antique silver square compact. It is decorated with white enamel on all outer surfaces and the lid is a beautiful aqua green guilloche enamel with hand painted roses. 

Measures 1 5/8" square. Still has original puffs and blush. The lever button that opens and releases the interior section works great. 

There is some wear to the enamel, especially on the bottom. 

It is not marked. I did acid test to see if this is sterling silver and it tested low 925, which may be 900 silver. However, I cannot say for sure that this is indeed silver.
