Any good place selling wide range of clear pebbles/crystals ?

[cosmicity]

Hi all,

I'm looking for clear glass pebbles/crystals for an art project.

It's a simple LED night lamp in which a small LED lamp will be placed inside a jar filled with said crystals, as can be seen in the pictures attached.

Does anyone know where I can get such clear and transparent pebbles? Or does anyone have any places which stocks a good range of pebbles/gravels/crystals? I've been looking at various art friend shops and asking around many aquarium shops, only to find out that they only have those opaque ones.

I apologise for somewhat hijacking the forum for something that's actually quite incongruent to the site, but any help rendered will be duly appreciated!
