| Geological description: | Quartzite coloured by hematite and goethite, in places the grain coatings giving some aventurine effect. |
| Comments: | Typical aventurine from Siberia, Russia. Price (2007) lists the main sources and notes that only small areas of stone would show the aventurine sparkle, larger items such as vases would not necessarily do so. Aventurine quartz from Egypt can look very similar. |
