The heart locket tattoo is a symbol of something that is close to the heart or very important to a person. Heart locket designs are fairly new. The tattoos feature a keyhole in the center of the heart.
Previously, lockets were not depicted with a center keyhole. Lockets were worn on a chain that was long enough to position the locket over the heart. This was an indication that the contents of the locket were very special to the wearer of the locket. The inside of the locket often held a photo of a loved one, either alive or deceased. Heart locket tattoos can be inked in a variety of colors. Designs around the heart are often part of the tattoo as well.
