Mosaic Cross

Beautiful handmade mosaic cross with blue tile, mirrors and a piece of broken dinnerware all with a black velvet backing. There is a number etched into the mirror on the bottom, however I am unsure of its significance. Previously loved, in very good condition with no cracks, crazing, loose tiles or mirror, repairs or discoloration. There are a couple of chips in the mortar at the bottom edge, see photo. This cross is not intended for hanging, there's no mechanism. It would be placed on a table, on top of a bible, etc. measures 11.25"H x 7.5"W x .875"D
