The coral that Nepalese jewelers work with has the shape of columns
and these columns are very different in size, and the faces are not always parallel, so the shape sometimes looks like a square or a trapezoid
this happens because natural coral is not processed to the desired shape, on the contrary, in processing, the main thing is to save as much coral as possible
and even in Nepal, rings with coral are worn together with rings with turquoise
sometimes on one finger
