In a special process, these items are reproduced in a proprietary blend of concrete and other secret ingredients, giving them the look and feel of real stone fossils.
Each fossil is made one at a time, by hand, in an individual mold. Because of the hand-made nature of the item, there will be variations in pigmentation, and small imperfections in the surface. While you can choose a general color range, please keep in mind that each fossil is unique, and color variations are inevitable.
