Carnelian agate Chinese zodiac “year of the pig” pendant

This is a beautiful carnelian agate carved into the shape of the Chinese zodiac "The Pig" which is the twelfth and the last sign of the Earthly Branches. In the continuous Sexagenary cycle, every twelfth year corresponds to Hai, and is commonly called "the Year of the Pig". This carved jade has a small hint of green. The bail and the chain are made of silver tone metal. The jade weighs 22.9 grams and measure 1.50 inches long (including its bail) and 1.25 inches wide. I found the chain and it’s included in the sale of this item. The chain is 18 inches long. In excellent vintage condition.
