The pendant is approx. 3/4" in length.  The surface glistens. The back is not hollowed out. It has a decorative grate that is finished with white gold or rhodium.  The white diamonds are pretty clear. The black diamonds are more of a graphite color. All the little diamond chips are bead set in sterling. If you clean and polish this pendant with a cloth, the silver bead setting will sparkle and increase the appearance of brilliance in the diamonds, but the black diamond chips won't show a lot of dark color, because the silver beadwork in the setting becomes so icy white and glossy after a good cloth polish.

 This pendant is fun, whimsical and well made.  The 18" chain is decent....plain, open link and strong.  I put my on a little thicker, diamond cut chain and had no problems with it accommodating the thicker chain. Delivery was prompt.
