So pretty! These cubic stars hang from a click closure hoop that is easy and secure. They are 18mm long, very discreet but the bling from high quality cubic is the closest we can get to a diamond. Cubic is not crystal which is cheap and scratches. Cubic is hard and brilliant that is why it is so often set in gold.

Each little cubic has it's own tiny window to let light shine through. This is the case with all cubic on www.therocks.ca Best quality!
