I got the Turquoise & it's gorgeous, whether it's lit or not.  The color is true to the photo.  It's really impressive when it's lit.

I had a hard time determining how much to buy for a gas fire pit table I was purchasing.  The table burn area is 17" square and a few inches deep.  I bought 3 of these 10lb bags, added to the 10lb bag that came with the table (I knew from reviews that it wasn't enough), and together I had more than I needed.  It's heaping full under the lid & I still have half of a 10lb bag of glass left.  I'm thinking I would have been fine with a total of 30lb.  Hopefully that helps someone else work out what they need.
