Wow, what an incredible and large Sunstone. This Sunstone has a ton of "Schiller", which is a phenomenon completely unique to Sunstone. As you can see from the pictuers, when this stone is rotated at certain angles, a sheet of copper appears. This stone is an amazing piece in that, it's very transparent from a face up view but also displays strong Schiller. This stone is completely unique. The largest Sunstone we've seen. A must have for the Sunstone collector. The original purchase price for this stone was $3300. We have it listed at 25% of that price. This is an unbeatable price. Natural and untreated. Easy money maker for the amateur or professional jeweler. For Proxibid bidders, shipping is a flat rate of $6, no matter how many lots won.
