Futhark Runes - Etched Black River Rock

A full set of Futhark runes (24 runes plus a blank), etched into smooth, black river rock.  
Please keep in mind that these are natural stones and will vary from set to set both in size and in etching. Every stone is different inside when etched. Some are close to white while others can be more subtle.  They are grouped by a general size category and etching result to be similar to each other.
