Glow in The Dark Fire Glass Gravel Stones Rocks for Fire Pit Use Fish Tank Aquarium Garden Decoration,2-4cm,680g/1.5lb (Aqua)

These look really cool in my turtle tank. I'm sure they'll get dirty quickly because turtles are filthy, but they look great now. I was worried they'd bother him at night but they only glow for a couple hours after his lights turn off. And they give off enough light we can see him in there for a little while. They look nice during the day too. There were plenty in the package. I almost didn't use them all but just took out other rocks to make it fit. I washed them off first with water just to be sure but there's no residue or anything coming off into my tank. A great addition to my aquarium!

a very nice touch to my hanging lanterns I put them it. it doesn't glow too brightly which isn't really a bummer. still would recommend it if u need glow in the dark stones of different sizes.

I used them for my fireplace and they are awesome. They really glow haha.

Come in a nice package but they don't glow to great. Not worth it for the price.

Although these Glow in The Dark Fire Glass Gravel Stones are a bit pricey, the fire glass does, in fact, glow for two to three hours after exposure to the sun. We washed them thoroughly even though the manufacturer did not suggest cleaning them. Then we dropped them individually into the bottom of a fish tank and the non-descript looking stones glowed a pretty shade of blue. I think they would look cool sprinkled into a landscape design. Overall, we are pleased by the glow in the dark aspect of these Glow in The Dark Fire Glass Gravel Stones. As the parent of kiddos with autism, there are causes near and dear to my heart.

I ordered these rocks to add some fun to our backyard. They can be used in so many different ways. I wasn't sure they would actually glow, but I have added a pic that shows them at night, spread around after a few full days of charging in the sun. They charged pretty well and the pic doesn't quite do them justice. They weren't as bright as I'd have liked, but they do glow. If you're looking for a light source these are not it. But they certainly add some fun to a gas firepit or a flower bed.

Weather looking at them in broad daylight, or enjoying their glow in the dark luminescence, these stones are attractive and have a natural look, even though they are, of course, man-made. Of course, you have to charge them with bright light for them to glow the way they do in my photo, but once you do that, they look terrific! Very bright.

These are really cool .... We don't get have our fire pit set up but they definitely glow in the dark and will be an awesome addition. I don't recall what the price point was for these but if I had to say anything could be improved, it'd just be the amount of rocks you get... I don't feel like what they initially sent will be enough to fill the fire pit. I suppose we could always mix them in with another variety of non-glow in the dark but I think I'd rather have all glow in the dark....
