This ammonite doesn't appear to have any repairs, as some larger ones often do. The surface is not completely smooth in all areas, as it does contain some natural empathic areas. It does contain high polish on most areas, and overall feels very smooth. The opening of the ammonite is not completely smooth, and does not contain many details as it is filled in with natural fossil sediment. This piece is a nice size and weight for holding during meditation. Both sides also flash differently, so it's fun to get lost in when in the sun.

Cleoniceras is a rather involute, high-whorled hoplitid from the Lower to basal Middle Albian of Europe, Madagascar, and Transcaspian region. The shell has a generally small umbilicus, arched to acute venter, and typically at some growth stage, falcoid ribs that spring in pairs from umbilical tubercles, usually disappearing on the outer whorls.
These ammonites present an impressive mineralization. The mineralization is produced in agate, with beautiful iridescent tones typical of this variety of quartz. This specimen, under the shell shows its precious structure of the suture lines.
