I have for offer this vintage French / European sparkler marble from the 1950s and 60s. In blue and green ocean colours it has a ribbon that reacts to UV light due to Cadmium. It's in excellent condition, but does have a couple of tiny flea bites which are hardly worth mentioning. It has ice like clear glass and ribbons of green, white and blue. It measures 20mm and in excellent condition for it's age. Regards Finderskeeperskent.
