Often known as the Blue Mineral, this stone ranges in colour from a bright blue to a turquoise blue. It can be found to have some red spots through it although it commonly presents as a deep blue-green stone. It polishes very well. My stone has greens running through the deep blue, and the colouring was what drew me to purchasing the stone. It is about 2 cm tall by 1 cm wide.
The stones are predominantly comprised of silica, but also contain copper and small amounts of various oxides. Shattuckite gets its gorgeous blue colour form the copper minerals present in the stone. It is relatively rare, but more interestingly is a pseudomorph meaning that it comes about when it chemically replaces another mineral such as quartz or malachite. It presents as a pseudomorph in oxidized copper deposits. As a pseudomorph, or secondary mineral it is often found in deposits with other secondary minerals such as azurite, chrysocolla or malachite to name a few.
The name of the stone is a derivation of its place of origin, being the Shattuck Mine, Bisbee, Arizona. Since then deposits have also been found in Namibia and Greece.
This stone is fairly rare and hard to come across, so if you spot one in a store I definitely suggest picking one up. As not as common, these stones even when small are a bit more expensive.
This stone is often known as the stone of reconciliation and renewal. It is believed to calm and create harmony and can be used to channel information from extra-terrestrials.
