Turn from a paperweight into a lamp by placing on one of our LED uplighters...or you could even place on the torch of your phone! The paperweights contain a photoluminescent jellyfish design within, meaning after exposing to a bright light, & then removed from the light source, the jellyfish will omit a gentle afterglow. On our images where the jellyfish is white in colour, it is either sat onto a white LED base, or unlit, & where it appears to be a bluish green, that is when it is 'glowing in the dark'. This captivating heavy-weight glass paperweight is hand blown by skilled artisan glass blowers, thanks to the craftsmanship, & unlike mass produced glass, no two pieces will be exactly alike. The bubbles in hand blown glass aren't consistent in size, which adds to the bubbly water effect, & there are no ugly seams in the glass, these paperweights started as a glass blob on the end of a blowing rod. Because each paperweight is an individual piece, shape & size will vary, but they are between 14-15cm tall, & 10cm wide. The paperweights alone are truly captivating, but when placed near or on to a light source, the jellyfish really 'pops' within the glass, & when in darkness, as long as it has been exposed to a bright light, it will also glow in the dark.
