Bluestone Thermal Dark Blue

Overlooking a tranquil pasture sits the Castro quarry. Named for the family of dairy farmers working the adjacent land, the quarry produces Dark Blue thermal bluestone. Lead by the 88 year old patriarch, the farmers nurture a herd that produces top quality milk. Rock Ridge takes a similar approach carefully working the stone so as not to lose any of the beautiful dark blue stone.
