Small Conopic jar

Found this little Conopic jar in a Bazar and always wondered if it could be real. Looks great, even under a Loop, and it is carved sandstone, not moulded. I read that in the later times of ancient Egypt they stopped using Conopic jars for body organs but continued to make them for "symbolic" use. Maybe symbolic ones where smaller...? Either way I'm glad I got it and hope to find out more at some point.
