Iceland Spar Viking Sunstone Optical Calcite Crystal Pendant Necklace
I wrapped a natural Iceland spar optical calcite crystal with flat gold plated wire. Like most Iceland spars, it has rainbow prisms. It also has interesting internal 3D inclusions. This pendant comes with a 24 inch gold filled chain. It has been lightly polished and it looks like ice. Calcite is a soft mineral and a certain amount of care should be taken when wearing it.
Optical calcite is a good cleansing stone and can amplify environmental energy. It is also restorative and helps to accelerate psychic development and spiritual growth. It provides insight in negative situations and aids in clarification during confusing emotional states. Iceland spar is helpful with Law of Attraction manifestation and can amplify intent. It can aid in removing energy obstructions and release you from fear by increasing positive attitude. It may improve your mood and release tension and stress.
Iceland spar is the name often used for optical calcite because that is where the crystal was originally discovered. The supply from Iceland has been mostly depleted, due to the use of the calcite in scientific instruments in the 19th and 20th centuries, and also for its use in gun sights during World War II. Optical calcite is also found in other places such as the United States and South America, but Mexico and China is where much of it comes from now.
Iceland spar is clear variety of calcite originally found in Iceland. It was often used in experiments involving light polarization, as it is well known for its double refraction qualities. It easily divides into rhomboid shapes. Some historians have speculated that it is the original sunstone mentioned in medieval texts (solarsteinn), that Vikings used to tell the direction of the sun on overcast days.
*An international team of researchers led by Guy Ropars of the University of Rennes in Brittany, marshalling experimental and theoretical evidence, says they have the answer. Vikings, they argue, used transparent calcite crystal -- also known as Iceland spar -- to fix the true bearing of the Sun, to within a single degree of accuracy. This naturally occurring stone has the capacity to "depolarise" light, filtering and fracturing it along different axes, the researchers explained.
Here's how it works: "If you put a dot on top of the crystal and look through it from below, two dots will appear. Then you rotate the crystal until the two points have exactly the same intensity or darkness. At that angle, the upward-facing surface indicates the direction of the Sun," Ropars explained by phone. "A precision of a few degrees can be reached even under dark twilight conditions. Vikings would have been able to determine with precision the direction of the hidden Sun." He added, "The human eye has a fine-tuned capacity to distinguish between shades of contrast, and thus is able to see when the two spots are truly identical."
Stones listed as natural, raw, or rough may have some imperfections and inclusions. Be sure to check all photos, including the zoom feature, for details about a particular stone. Please see photo with ruler for size. Colors may vary with individual monitors.
Many stones are susceptible to fading, and they should be kept out of direct sunlight. Do not use hot water or salt water to clean them.
