crystal quartz sand

How absolutely lucky I am to be able to wiggle my toes in it!
"The sand on Siesta Key Beach, Florida is unique from any other beach on the planet and is comprised of 99.9% quartz crystal. Imagine walking on baby powder or flour. This is what the sand feels like on Siesta Key Beach.
Siesta Key is the recipient of Woods Hole Oceanographic Institute's "World's Finest, Whitest Sand" award based upon its content (99% quartz), texture (crystal shapes), and the amount of shoreline (quite wide)."

The Master Sandsculpting Competition starts in about a week, on Nov. 14th. You really must check the link... you will not believe what they sculpt out of this sand!!
