The condition of the smaller piece was rather poor when I first bought it.
But with a little soap and water the little fella has been restored to its original luster. Which goes to show that carnelian is a very hardy stone.
The backs are flat and plain.
They date from late Qing to 20th century and are popular with both local Han Chinese as well as minority groups.
Carnelian boys are also sometimes used as insets for silver accessories such as bracelets and hairpins. However I am not lucky to possess any piece in its orginal setting.
I salvaged mine from the local flea and the silver or hat originals must long have decayed. But still they are attractive and collectible.
