Hi Katrine, we got it at Nova Tile and Stone, Minden NV but they told me they can get it through 2 or 3 different distributors. Here's the description from the invoice, maybe it will help: "1x3 Tumbled Quartzite Brick Mosaic on 12x12 mesh Golden White"

Thanks - I'm going to check into it - all I can find locally is white quartzite.

I searched online using the description that I posted and found a number of places online where you can get it.
