Labradorite
Labradorite belongs to the Feldspar group of crystals (the same group as Moonstone that we connected with last week). It was first identified on Paul’s Island in Labrador, Canada but is now found in other locations worldwide. The colour of Labradorite can be grey-green, dark grey, black or greyish-white and it displays an iridescent optical effect (or schiller ) in flashes of peacock blue, gold, orange and green. This flash is known as labradorescence. Some rarer forms of La

Strawberry Quartz
Strawberry Quartz is one of the lesser written about crystals available and there are some differing opinions on the mineral content and appearance. I have done some research online and have written the below information based on the crystal that I have always known to be strawberry quartz – as seen in the picture. Strawberry quartz is a pink variety of Quartz that has the mixture of Goethite and Iron Oxide that infuse the crystalline matrix. The colour ranges from pale pink

Sodalite
The composition of Sodalite is sodium aluminium silicate and it gets its name from the sodium content. Sodalite does not belong to a family of crystals like the quartz crystals we have already worked with, however in mineralogy it may be classed as a feldspathoid. Sodalite is found in all shades of blue and may contain white streaks of calcite within it. Sodalite is the main constituent of Lapis Lazuli, along with other minerals. Sodalite is usually associated with the third
