Silver Pearl® #5
Silver Pearl® quarry #5 is a dark grey stone with large, shiny pearls and is available in two types: Silver Pearl® and Silver Pearl® Building. Colouring and quality of both materials are the same, but the shape and size of the crystals is different. That is why Silver Pearl® Building is cut at a 45 degree angle, increasing production efficiency. Uniform colour, competitive pricing and high availability make Silver Pearl® quite unique and a perfect project material.
