The most abundant alternative to mined crystalline silica sand is what nature has provided plenty of by oceans and rivers. Beach and riverbed sand is naturally low in dust and hardly gives off any residue when touched. This is because even though the sand is composed of crystalline silica it does not contain the dangerous dust.
