SILVER PEARL® #5
Silver Pearl® is a dark grey stone with large, shiny pearls. It is available in two types, Silver Pearl® and Silver Pearl® Building. Colouring and quality are the same, but Silver Pearl® Building is cut at a 45 degree angle to increase efficiency and lower prices. Such cutting is possible due to the shape and size of crystals. Uniform colour, competitive pricing and high availibility make Silver Pearl® quite unique and a perfect project material.
