Description

Victorian bluestone is an olivine basalt formed from volcanic activity 4.4 million years ago, quarried throughout Victoria's western plains. This dense, fine-grained igneous rock has been Melbourne's quintessential building material since the 1830s, demonstrating exceptional durability in Australian conditions. The material develops an attractive weathered patina over time, transitioning from deep blue-grey to lighter grey tones.

Victorian bluestone has been quarried since the 1830s, coinciding with Melbourne's establishment. First used extensively during the 1850s Gold Rush period for warehouses, prisons (Pentridge), and civic buildings (Old Melbourne Gaol, 1841). The stone formed from Newer Volcanic Group basalt flows 4.4 million years ago across Victoria's western plains. Historic quarries operated in Clifton Hill, Brunswick, and Coburg (now Coburg Lake). Modern extraction continues at Lara, Bamstone (Southwest Victoria), and other locations. Over 180 years of proven performance in Melbourne's climate demonstrates exceptional durability, with many heritage buildings still featuring original bluestone elements. The material has transitioned from primarily structural use to contemporary architectural cladding and landscape applications.
