Where to find precious gems

Most of the known gem minerals in Victoria were discovered during the heyday of alluvial gold mining in the s and s.

Although Victoria provides a rich source for a variety of polished stones and specimen minerals for fossickers, the potential for new commercial production of precious and semi-precious gem minerals is low. A possible exception to this is Beechworth diamonds, of which several hundred have been found in the Eldorado Lead along Reedy Creek. The primary hard rock diamond source has not yet been located.

The one-and-a-half mile Jade Cove Trail is a popular spot for jade hunters searching for the greenish-hued gemstone, which forms due to subduction or when oceanic and continental plates collide.

The Pueblo believed that turquoise got its color from the sky, while the Hopi thought the gem was produced by lizards scurrying over the earth. Sunstone, a member of the feldspar group, can be an orthoclase feldspar or a plagioclase feldspar, depending on chemistr y. Both can show aventurescence — a sparkly, metallic-looking luster caused by flat, reflective inclusions.
