Icelandic Feldspar
Also known as âoptical calciteâ and âViking sunstone.â Photo taken from Wikipedia.
âIcelandic spar [or optical calcite[ is a transparent variety of calcite, or crystallized calcium carbonate, originally brought from Iceland, and used in demonstrating the polarization of lightâ (Wikipedia, par. 1). As a form of âViking sunstone,â itâs thought that Icelandic feldspar was used by Vikings as a navigational tool.
Magically, optical calcite can act as a crystal for clearing negative energy and emotions in order for positive energy to make its way back into a space. A lot of sources write that optical calcite can be used in a similar way to clear quartz (i.e. to amplify intent and be programmed for specific purposes). It can also be used to clear energy blockages and help re-balance energy centers.
Scientific Properties
2.5 to 3 hardness on the Mohs hardness scale; clear in colour; double refraction (or birefringence).
Magical Properties
Growth, development, energy clearing, energy purifier. Good for use in meditation and helping to see situations in a new light.
Peach Notes
While most of the information presented here I collected from various metaphysical websites, I thought Iâd make a quick note on Icelandic feldspar/optical calcite and how I personally use it. The stone is also called sunstone but when holding my piece of optical calcite, it feels like Iâm holding a piece of ice in my hand. Itâs like inhaling a breath of cold, wintry air, and negative emotions end up melting away. This stone is excellent for mental clarity and helping ground myself while Iâm meditating, journeying, or trying to dive into my own past lives. It helps me sift through all the information that I receive and help discern between the truth and whatâs false. I personally keep it on my computer desk and fiddle with it while Iâm writing papers since I find that it really helps me sort out my thoughts. Also: when I hold up my piece of optical calcite in the light, the light refracts into rainbows and itâs really, really beautiful.
