Thunderstone Quarries

Rundle Rock was named by the stone masons who quarried it from the base of Mount Rundle in the late 19th century. The stone masons thought this visually attractive stone was easy to work with and suited to a wide array of uses. Its unique texture, distinct black and brown colours, variety of shapes and natural durability made Rundle Rock a popular commodity. Today, it continues to be popular for commercial and residential applications and is a favorite among, architects, designers, landscapers and masons. Established in 1960 by George Biggy Sr., Thunderstone Quarries remained a family run business for over 40 years. Today, Thunderstone is owned and operated by Resman Holdings Ltd.
