Combination Safe

This ring has a WORKING two digit combination safe integrated into the design.  When the proper combination is input, and the lever depressed, a secret compartment opens to reveal a 24 karat gold coin.  The coin is actually a legal tender coin from Australia and portrays Queen Elizabeth II on the front and a kangaroo on the back.  It is designated 0.5 gram and .9999 gold, which is also called fine gold, or 24 karat gold.

The ring is 7.5mm wide and the top is around 14mm diameter.
