Featured here is a large uncut piece of a fluorescent Septarian Nodule from Madagascar, it fluoresces yellow under (SW and LW). It would make a good addition to your awesome specimen collection. The first two photos are LW {the opposite of how we usually set up the photos}, the next two are SW, and the last four are daylight. The dimensions of this piece are: up to 3" width by up to 5" length by up to 3" thick. The lot weighs about 1 pound and 14 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. Please do not bid on these items if you intend to view them with a poster lamp, they will not fluoresce. They will fluoresce as shown if you are using a fluorescent mineral lamp, designed for that purpose.
