Our quarry stocks over 300 tons of natural stone from all over the United States including South Bay Cottage wall stone,  Saratoga Cottage wall stone and the popular Pennsylvania bluestone fieldstones & flagstones. Our pre-cast products include Unilock pavers and retaining walls and Dutch Quality veneers.

Collier Stone Company also has veteran stone fabricators on site to cater to your custom stone cutting and fabrication needs. Our fabrication shop specializes in granite, quartz and soapstone - and the creation of any architectural limestone and sandstone product our customers might desire including hearthstones, wall caps and keystones.
