This is a natural stone and color can vary from white to gray black to

Arkansas stones are 100% quarried in the Ouachita Mountains of central
Arkansas. They are highly sought after worldwide for their superior ability to
sharpen knives and woodworking tools, as well as to put surgical quality edges
on a wide variety of instruments Arkansas stones produce these fine edges s
with less wear that man-made stones. Arkansas stones are classified as
Novaculite, which is extremely hard and fine grained rock containing almost
pure silica. These stones are classified in 4 grades and progress from Soft to
Hard to Translucent and finally to Black. Each grade is based on the specify
gravity or density of the mineral and not the grit or particle size. The
grades with more dense or tightly packed particles will produce a finer or
sharper edge. In addition, stone grades are not determined by color, as color
alone will not differentiate the hardness of different stone grades. Each
grade may contain any of the following colors: black, blue-black, charcoal,
grey, white, multi-color, brown, pink or red, or a combination of these colors
in a single stone. These stones come in a leather pouch to protect them when
not in use. All Arkansas stones work best with light mineral honing oil to
suspend the metal particles produced by the sharpening process which prevents
clogging of the pores of the stone.
