Purple Slate

Purple Slate, quarried in Vermont from our Vermont slate quarry that has been in operation for over 150 years, is a rare stone used for interior and exterior applications. Because of its superior properties and performance, unique plum color and rich texture, architects specify this natural Vermont slate for interior slate flooring, exterior paving stone, stair treads, fireplace surrounds, slate wall cladding including slate wall shingles, countertops and roofing. Purple Slate is available in natural cleft, honed and cascade finishes.
