Natural Eye Agate beads in black and light brown. These beads feature natural concentric circles in white and shades of brown. The agate is highly polished and high domed. These are beads (drilled lengthwise) but I use them as cabochons as they are flat on the back ith a clearly defined bezel line (see eye agate three piece cuff in my shop). They measure approx. 7/8" x 1 1/4" (blk) and 7/8" x 7/8".
