Featured here is a large size uncut piece of a fluorescent Septarian Nodule from Madagascar that fluoresces yellow (SW and LW). Use this piece for cab cutting rough, or a fluorescent mineral specimen. This piece measures: up to 3" width by up to 4" length by up to 2-1/2" thick. The first two photos are LW {the opposite of how we usually set up the photos}, the next two are SW, and the last five are daylight. This lot weighs about1 pound and 4 ounces.
We use a 36 watt fluorescent lamp specifically designed for viewing displayed fluorescent minerals. Our minerals are photographed dry, and no type of 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. Thse 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.
