Brass Embossed Belt Buckle White REMOVABLE Stone w/ Letter D on it

Description

This is a beautiful belt buckle.  It has a white stone with a black letter "D" on the stone in a setting that is on the buckle. .
I believe that this item is brass because it has a gold tint to it.
Please forgive me if I am wrong about the type of metal.
I am not a metal expert.
The designs are beautiful and go well with the fancy letter D that is on the stone. T
he stone is sitting in a casing that can be removed by unscrewing the screws on the back of the buckle.  You can put whatever you want in place of the stone.  (For example, a photograph could be cut to size and put in.)
The letter D on this item has some scratches across it. I ran my fingernail over the scratches and they are not deep but they are into the stone. Please see the pictures for details about the condition.
Consider these pictures part of my description.
Otherwise, I could not find any damage on this buckle.
Please contact me if you have any questions.
Thank you for looking!
