Help me! Where can I source large acrylic stones??

[deepdarkwood]

My dancing shoes got a bit of a pounding last time i was out and I came back minus two of the stones. I thought it would be easy to just hop on ebay and find replacements, but apparently not!

They are largeish & clear (although I could replace with black/grey at a push) I've found a site that stocks the right shapes here www.streamers.co.uk/ but they don't have the right colours
I'm looking for an octogen 25x18mm and an oval 18x13mm.

I don't expect anyone to trawl through all the sites checking the right sizes/colours, but could anyone point me at the right sort of sites (or even the right sort of things to be googling...)

Many many thanks!
