Check to make sure the item is an authentic Dynasty Gallery Product. Every item that we sell with Glow in the Dark will glow. There's no "defects" or one that does that work. Each and every one of our glow in the dark products will glow because the phosphorus is already fused into the glass. The item releases/emits the light it absorbs immediately. It doesn't not "hold a charge" like a battery.


If your item is a Dynasty Gallery Glow in the Dark item, follow the steps below to see it glow:


  1. Place your item under a light or in a lighted room. Wait approx. 5-10 mins so that your item is able to absorb some light. 
  2. Take your item into a dark room, or put it in a dark bag. 
  3. You should now be able to see your Dynasty Gallery item Glow in the Dark!


Quick Facts:

  • The "glow" is a bluish/greenish color. 
  • They are 100% glass! :) Is that a real jellyfish?
  • "I left the item out all day and it didn't glow at night." -- The item releases/emits the light it absorbs immediately. It doesn't not "hold a charge" like a battery. Therefore, the item will not emit glow hours later.
  • Could my item be defective? No, each item that is sold as glow will have the phosphorous already fused into the glass. 
  • Orange Jellies will appear to glow less because "amber glass" that makes the beautiful orange jellies naturally blocks light/UV rays. We will continue to offer Orange Jellyfish items to capture the natural beauty of the Sea Nettle Jellyfish's bright orange hue.
