Explore the Miners Heritage Walk-In Mine Tour in Rubyvale, QLD – Australia’s largest underground sapphire mine tour. Originally founded as a working mine in 1982, it has transitioned into offering mine tours since its underground showroom completion in 1984. A modern above-ground air-conditioned showroom was added in 2004 for the 20th-anniversary celebration. Nestled in the heart of Queensland’s sapphire fields, Miners Heritage invites you to experience underground tours, gem fossicking, Australian Sapphire Jewellery shopping, and leisure in the undercover area.
