Sardonyx Crystal Tumblestone
This listing is for one large Sardonyx tumblestone from India, supplied as a single stone only.

As a tumbled specimen, it is suited to collectors who enjoy the smooth, naturally varied appearance created by the tumbling process.
Mineral and Geological Context
Sardonyx is a recognised variety of chalcedony, a microcrystalline form of quartz. It is traditionally identified by its layered or banded appearance, with contrasting tones that can create attractive linear, curved or softly blended patterns across the stone. Sardonyx belongs to the quartz family and is valued in mineral collecting for its distinctive bands, colour contrast and ornamental character.
The supplied specimen is identified as Sardonyx and is associated with India. Each stone may display its own individual combination of colour, patterning and surface detail. Variation is a natural feature of mineral specimens, so the exact visual arrangement of bands and tones will differ from one tumblestone to another.
Appearance and Display
This 30-40mm average-size tumblestone works well in a cabinet, bowl, shelf display, desktop collection or decorative mineral arrangement. Its rounded tumbled form makes it easy to handle and suitable for showcasing alongside other crystals, polished stones and geological specimens. Sardonyx can be especially appealing to collectors who appreciate the relationship between natural pattern, colour variation and the geological history represented by ornamental stone.
The photograph shows a representative example; the specimen supplied may vary naturally in colour, shape, size and detail.
