I love the unique design of this 18K pendant. It features a cabochon rhodochrosite on a flat round slice of black onyx, all set in a geometric setting. It's a striking color combination! 

The bail is large and it opens, so it's easy to clip on to a variety of chains. 

It measures just under an inch in diameter. If you include the bail, then it's approximately 1.5 inches.  It weighs 8.4 grams.
