Sea Sediment Jasper Beads | Impression Jasper Beads - African Impression Jasper and Sea Sediment Jasper are only two of the names for this gorgeous gemstone that is also referred to as : 'Aqua Terra Jasper' (the blue & green colors), 'Impression Jasper' (for it does make quite the impression), as well as 'Regalite' (for it is quite 'regal' looking!), Spider Web Jasper and Variscite. This stone has proven to be somewhat of a mystery. We know that it is a jasper material from Africa -- but no one in the market knows what exactly to call it yet! Jasper was a favorite gem in ancient times and is referenced in Hebrew, Assyrian and Latin literature. It is a fine-grained chalcedony. The name jasper comes from the Greek and means 'spotted stone'.
