Arkansas stones are mined in the Ouachita Mountains in the state of Arkansas in the United States. Arkansas stones are made of novaculite, a naturally abrasive material of high density. Arkansas stones consist of silica, but unlike synthetic abrasives, do not consist of individual abrasive grains of the same size. Arkansas quartz structure consists of fused crystal grains of different sizes.

Bethesda Black is preliminarily lapped and does not require lapping after purchase. Bethesda Black stones should be used with water or oil as a lubricant.

Bethesda Black stones may have a color pattern, slight natural imperfections, and inclusions.
