We've all seen green jade, that stone is comparatively easy to find. Somewhat rarer are the other colors, including red, white, and even lavender.
 But black? Finding quality pieces of this variety is sometimes harder than finding a quality diamond!  They both are about 5-6 inches wide,
and 4 1/2 inches tall. The top piece is 2 inches thick, and the bottom one is about 1/2 inch.  Those are white quartz inclusions you see in the lower slab, and some of them in crystal shape(upper right, top center)
Top - $28.00
Bottom - $23.00
