The top of this ring is quite large at just over 1 inch long. Icelandic Spar is also known as \"The Viking Sunstone\". Vikings were able to look through Icelandic Spar, and use its light polarizing property to be able to locate the position of the sun on a cloudy day. This was important, as with out night stars or the sun, they would not have been able to chart a course at sea.  Light passes though the crystal and exits in two paths, creating a double image of an object. This would make the sun more noticeable on an overcast or foggy day. It could even allow for the Vikings to find the sun in the Arctic when the sun falls bellow the horizon. As can bee seen in photo #2 you can actually look through the Icelandic Spar from the bottom of the ring. Icelandic spar is more specifically a variety of calcite. This gemstone is a Cushion-shaped Cabochon Cut. Cabochon refers to a gemstone that has been shaped and highly polished instead of being faceted. This is an old hand cut gemstone with great luster and internal feather crystal formation feather and inclusions.
