Black Canyon (Overview)
USI Black Canyon features a rich, dark black color that immediately catches the eye. This bold and contemporary look makes it a perfect fit for modern design spaces. For best results, it is strongly recommended to apply a penetrating sealant to any dark limestone product, as UV light can cause color fading over time in unsealed limestone. *Black Canyon limestone is known to sometimes contain pyrite (fools gold) deposits. This is an attribute inherent to this type of stone.
