Cerulean Cube (9x9x12) is all about blues. Sky blue, cobalt blue, aquamarine blue. All mixed up. All complimenting each other. The inner cube is composed of lead and unleaded crystal, combined with rare filter glass, dichroic glass, and glass I tinted myself with metallic dyes. It's cut and recut to create the prismatic effects you see. It's affixed to the prongs of an anodized aluminum base that is quietly spinable. Felt is on the bottom of the base.
