Featured here is a large size uncut piece of fluorescent Wernerite from Otter Lake, Canada that fluoresces yellow (SW) and brighter yellow (LW). Use this piece for cab cutting rough, or a fluorescent mineral specimen. This piece measures: up to 4" width by up to 4" length by up to 1-5/8" thick. The first three photos are LW {the opposite of how we usually set up the photos}, the next three are SW, and the last three are daylight. This lot weighs about 1 pound and 14 ounces.
Fluorescent Mineral Collector Piece
We use a 36 watt fluorescent lamp specifically designed for viewing displayed fluorescent minerals, it has SW and LW modes. Our minerals are photographed dry, and no type of photo enhancement is employed, as it appears under our lamp is how it photoed and is presented on our listings. We display shortwave photos first, then long wave photos. If the mineral does not fluoresce under one those waves, it will be noted in the listing. These items will not fluoresce as shown with a poster lamp. They will fluoresce as shown if you are using a fluorescent mineral lamp, designed for that purpose.
We do our best to represent the true colors of our materials. Please remember there are many factors to consider, such as how your computer monitor displays the photos. Also SW minerals will not fluoresce with most of the UV flashlights.
