I did some research on the blue quartz for pools on the internet and this is what I came up with. Some of the trade names for the Blue Quartz is QuartzBrite, ColorQuartz, DiamondBrite, Sunstone, QuartzScapes, and QuartzOne. It looks like this product is mixed in with the plaster and then sand blasted lightly to remove the plaster and expose the blue color chips of the Quartz. On the sample that the pool installer had this product felt much smoother than a pebble finish sample that he let me see. I cannot tell if it is really Quartz.
