This bracelet from Canadian company Nogu is very cool. I’ll let them tell the story: This is Firefly Glass, It’s designed by NOGU Studio in Toronto. Nope, there are no electronics involved. The bracelets are made of genuine lampwork hand-blown glass and once energized under a light source emit a spectacular glow. They are the grown up luxury version of your favorite glowing baubles as a kid.

During the blowing of the glass, small phosphorescent particles are suspended inside the glass and when charged explode with a brilliant emerald glow.

They are handcrafted & beautifully gift boxed. They are the perfect summer accessory and are guaranteed to add some light to your day (or night!)

It’s priced at CAD$49 but at the time of writing they were running a couple of promotions.
