Mexican Onyx Polished Cube - Pick Your Exact Piece, 3 or 4 Inch

A polished cube turns Mexican onyx's layered bands into modern, geometric decor. Each cube shows earthy tones and soft translucency, with a flat cut base that sits steady.

It looks sharp on a bookshelf, coffee table or desk, and it doubles as a stylish bookend or paperweight. A stone cube is a thoughtful gift for someone with modern taste, a new office or a home that leans minimalist. Its soft translucency glows when light shines behind it.

Each numbered option is pictured on its own, so the piece you see is the piece you receive. Cube 01 is about 3 inches on each side, and cube 02 is about 4 inches.

About Mexican Onyx

Despite the name, Mexican onyx is not true onyx. It is banded calcite, sometimes called onyx marble. Calcite has a hardness of 3, so it carves easily and takes a soft polish.

Stone Meaning: Mexican onyx is traditionally associated with calm and clarity.
