Set 5 cups and saucers gridded in translucent mineral

Set of 5 cups and 6 saucers (1 cup free of which the handle is peeled off) The cups are made up of polished quartz-type mineral squares, assembled and joined in deep green. It is a rather atypical ensemble that seems to be inspired by the jade tea service of the ming dynasty. No details on the date of manufacture but in my grandmother's attic since at least 1975: ) The set is in its juice. Some cups have small defects and some handles seem to have been glued or consolidated but discreetly. Every cup and saucer is unique and in texture, colour etc. Diam saucers: 12 cm.
