Optical Calcite is known as the  "Viking Sunstone". Its optical effect made it useful when navigating the open seas. Here is an interesting article about Optical Calcite / Icelandic Spar that explains birefringence and historical use

Faq

Will I receive the exact item shown? Will my item look like the picture?

All items that are in the 'one of a kind' section will be the exact item shown. Everything else will look very similar, if not identical to the photos shown. In the description, you will see 'you will receive the exact item shown" if it is a one-of-a-kind crystal or item. I take all my own photographs of my actual inventory and never use stock photos.

What if it breaks?

You don't pay for broken items. I package everything super carefully, but if something does arrive broken,  just send me a picture of the broken items and package and don't throw anything away. I also ensure all of my shipments, so I will file a claim and you will be given a full refund. See our policies for more information.

Can I return it?

Yes, I accept returns that are mailed back within 15 days of delivery. See our policies for more information.
