   Loved the video Dale. I didn’t know there were rocks like that. Do you polish them in a tumbler once got to shape and size?
   Thanks for sharing!

     No, none of these specimens have been through a tumbler, just washed with water and a toothbrush. And they were all found right here in the USA.

     Hi Kathy, most of us ‘rockhounds’ do not purposely finish fluorescent rocks into cabs that can be made into jewelry, because without the correct UV wave they would not fluoresce. However many gemstones used in jewelry making DO fluoresce, such as certain diamonds, fluorite, calcite, some opals, etc. (At the beginning of the video I point to some rubies in zoisite that have been polished.)

   Great video Dale. Our rock club puts on such an exhibit in a room during our yearly gem & mineral show in December. It is so fun to watch the faces of people when suddenly they are surrounded by greens, blues, red, and yellows coming from rocks that just minutes ago looked so bland and dead. We have several members in our club that collect nothing but fluorescent specimens.

   I am not much of a rock hound but love to get finished cabs to wire wrap of set in silver. I thought you had to treat “rocks” for them to glow in the dark. Didn’t know it was natural. Haven’t had any at the Rock/Gem show I go to locally. Thanks for the education. Do you have any on your website? I really enjoy and learn for your daily tips!!!!!!!! Keep’em coming!!!!

     Yes Sharon, WS does have cabs that will fluoresce. Check out the list I made in another post here and then have fun shopping! Just remember that in order to see the fluorescence the stone must be exposed to the correct UV waves.

   Dale, you always show us such remarkable pieces. I really enjoy watching your all of your videos and learning all about the various rocks and gemstones. Now you show me flourescents I have never seen so many. I have a flourescent opal my son purchased for my birthday years ago. I had no idea it was a flourescent. I thought it was just a pretty, sparkley, opal stone. Thanks for the great news. I will enjoy my opal even more. I can’t wait to tell him exactly what type of stone he bought me. Keep it coming, girl. Happy New Year everyone.
