This is a well constructed solid brass cross pendant. It was painted with black enamel so it could be worn as mourning jewelry. This is a simple black cross with no decorations. It has a heavy weight brass jumpring so it could be attached to a chain etc. There are a few minor scratches of the paint, but nothing that you would not expect for an antique cross of this age.
Mourning jewelry has been in use as far back as the 15th century, but was popularized during the reign of Queen Victoria. After she lost her husband Prince Edward at a young age in 1861, she went into a deep mourning period. She wore black for the rest of her life and required the court to wear black for 3 years! The populace followed her example. Here in America, mourning jewelry became popular during the civil war. Strict first stage mourning jewelry was all black colored.
