SKU: SEDROK051 Category:

Portland Stone is a variation of limestone which formed during the Tithonian stage of the Jurassic period. It has been quarried since the 14th century, notably on the Isle of Portland, Dorset. This pale rock is sufficiently hard to resist weathering but yet soft enough to carve hence it makes an ideal architectural material. It was famously used for the construction of St. Pauls Cathedral and Buckingham Palace in London. Like most limestone, Portland stone formed in sub-tropical seas where wave action even resulted in the micro oolites visible in some pieces. Specimens are supplied in a labelled card tray.
