Here is an Absolutely Gorgeous slab of Black Colored Millefiori for Cabbing or would make a fantastic addition to any collection!! Millefiori is a glass made with fused glass rods, VERY COOL material!! This piece measures approx. 4 1/4" by 1 1/4" and is 6-7 mm thick. It weighs 2.0 oz. I pictured this piece wet/dry on both sides and through the light to show its beauty and potential, it is not polished. As always there may be imperfections, sold as-is. Shipped same day as purchased if during business hours, if not, next business day. Happy Cabbing/Collecting!!
