Mini diamonds in sintered glass made from recycled windows and natural minerals. Each moulded piece is 1/2 inch wide and 3/4 inch long and 1/4 inch thick. As they are slightly thicker than some of our vitreous and stained glass they should be used for making borders or as relief accents. They are strong and durable and are UVA and frost resistant. Combine them with Optic Drops to make fantastical landscapes or flowers or Oriental motifs. 50g=+/-24 pieces. 500g=+/-240 pieces.
