These are genuine Novaculite from Arkansas. Novaculite is a sedimentary rock composed of microcrystalline quartz, it is also recognized as a re-crystallized variety of chert. It is a high-purity silica, composed of more than 99 percent pure silica. The name is applied mainly to formations in Arkansas, Oklahoma, and Texas and is derived from the Latin word novacula, meaning razor stone. Novaculite is the rarest and finest abrasive stone in existence.Found in depths of 250 to 900 feet, Novaculite was formed during the Mississippian and Devonian ages (about 350 million years ago). The stone naturally resists erosion and forms prominent ridges in the Ouachita Mountain range. The quantity of available Novaculite is immense. Whetstone quality novaculite is found predominantly in Garland and surrounding counties in the massive lower division formations. However, individual quarries exist from Little Rock in Pulaski County westward towards Hatton in Polk County. The amount of Novaculite that exists in these formations will allow for the continued production of sharpening and abrasive products for as long as the demand and profitability is there to sustain the industry. Color may vary with each stone.
