Ashford Black Marble – Derbyshire £2.25 – £6.00 ex VAT
Size
2" x 2"3" x 2"4" x 3"
Ashford Black Marble samples originate from Ashford-in-the-Water, Derbyshire, UK. Despite its name, this rock surprises many by being classified as a fine-grained Sedimentary Rock instead of a Metamorphic one. This classification is due to its true nature as a dark limestone rather than a genuine marble. Ashford Black Marble earns its reputation for ornamental purposes, showcasing a stunningly shiny black surface when cutting and polishing it. The rock’s origin dates back to the Carboniferous period, and it boasts a generous amount of bitumen, giving rise to its dark grey hue that transforms into a mesmerising glossy black appearance upon polishing. Supplied in various sizes, each specimen comes presented in a white card tray with an accompanying informative label.
