Featured here are six approx. 1-1/4" (in diameter each) they are: one Willemite and Calcite sphere from Sterling Hill, Ogdensburg, NJ that fluoresces beautiful, bright red and green under SW, one Fluorite from the "McCracken Mine" in AZ that fluoresces blue (SW) and (LW), one Wernerite sphere from Otter Lake Canada that fluoresces yellow (SW) and brighter yellow (LW), one Opal sphere from Utah that fluoresces green, and one sphere of Willemite and Calcite from the "Purple Passion Mine" in AZ that fluoresces green and red(SW). These spheres are ready for your awesome home, or collection as they are. This lot contains all of these spheres. The first four photos are SW, the next four are LW, and the last two are daylight. The lot weighs about 6 ounces (all spheres together). #1425 We use a 36 watt fluorescent lamp specifically designed for viewing displayed fluorescent minerals . The lamp was built and designed by "Way Too Cool" of AZ (they have a great website with lots of good info on fluorescent minerals and lamps). 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. 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.
