The difference in between Diamond Brite Aqua Quartz and Diamond Brite Aqua Blue is the size of the aggregate.

If you are looking for something similar to Diamond Brite Oyster Quartz with a hint of blue, please ask your pool builder to provide you with a sample of the Diamond Brite Blue Quartz.

Thank you so much for your help. My pool is somewhat contemporary with ivory travertine coping and decking. My concerns were that we did not tile the tanning ledge...I would have if I'd had clear understanding about plaster, so therefore I was worried about the ledge matching my Travertine. Do you think the blue quartz will still be light enough to blend with my travertine? That was reasoning behind the oyster quartz..but I wanted just a little more pop to it...my builder did not have a blue quartz customer in my proximity that was vacant for me to view. I have been researching and spending hrs upon hrs debating which color choices fit my needs...your simple response has been more valuable than all my countless hrs combined..once again thx u so much for your input!
