Bill Cook worked for Sawyer Labs in Cleveland, Ohio for much of his career and was involved in high purity synthetic quartz crystals for electronic and optical applications; and had a subcollection of a wide variety of synthetic crystals such as this one.

Tourmaline - Tourmaline King Mine, Pala, San Diego Co., California, USA More info: https://www.irocks.com/minerals/specimen/52463 Complete all around and with no damage, this tourmaline is literally like something out of an old museum, if you happened to get to see old King Mine pieces in a drawer from one of the oldest USA collections. It has a termination composed of many individual terminations, all well-formed and in good shape, atop a green-colored body. It is dark in room lighting, but sti

Azurite - Christiana Mine, Lavrion Mining Dist., Lavreotiki, Attica, Greece More info: https://www.irocks.com/minerals/specimen/53146 This is the best thumbnail we know of in a small pocket obtained from a Greek collector of note, who had kept it back for himself when handling this pocket some years ago.

Fluorite - Minerva Mine, Cave-in-Rock, Hardin Co., Illinois, USA More info: https://www.irocks.com/minerals/specimen/52691 This remarkable teal-blue fluorite was lurking on Jack's shelves for decades without me realizing how beautiful it was, because of a layer of dust. He had some specimens way up on shelves near the ceiling, to squeeze more into the room. Cleaned, we realized that the true color of this fluorite is a vibrant teal-blue, which is seldom seen. We have no label nor mine name, as t
