These sky eye jasper beads come primarily in shades of gray, tan, red, and golden yellow. We were told that this form of jasper gets its name from the pretty sky blue color found in its mix of shades - well, our stock must be more representative of Seattle skies (not much blue!). But no matter the shade, these semiprecious beads have gorgeous markings, including roundish "eye" splotches that are especially lovely on the larger focal beads! Sky eye jasper is mined in Mexico. In general, jaspers are an opaque form of semiprecious chalcedony, and their physical properties are those of quartz. Jasper beads take a fine polish, but be aware that jasper jewelry components are often sealed with petroleum products. Their polish might wash away in water, so clean with a soft, dry cloth.
