Five kilos of light colored Mexican onyx gives you plenty to work with, whether you are filling a glass vase, building a garden border or stocking up for a craft project.
The soft creamy bands look lovely in a bowl on a coffee table, around the base of a potted plant or in a water free tabletop display. Lapidary hobbyists can cut and polish the stones, and each stone is a clear example of banded calcite for a rock collection. A bag like this also makes a practical gift for a rock tumbler owner or a crafter.
Stones range from about 1 to 3 inches thick, 2 to 4 inches wide and 3 to 6 inches long, in an assorted random selection. The photo with a hand shows the scale.
Despite the name, Mexican onyx is not true onyx, which is a banded chalcedony. It is banded calcite, sometimes called onyx marble, a softer stone at about 3 on the Mohs scale that takes a warm, waxy polish.
