An impressive picture jasper cabochon with distinctive colour and markings. Although large, this stone has been finely cut so it's not at all chunky.
Picture jasper is a variety of mudstone which can be found in many locations around the world. This striking cabochon stone comes from material mined in the United States.
The markings present in picture jasper are unique to the geographic region from where the stone was mined.
With jasper being a variety of quartz it's relatively hard which makes it ideal for cutting. For this reason jasper cabochons are widely used for jewellery.
Jasper is an opaque stone that can occur in many different colours. It tends to take on a high polish and the name will often give some clue about the location where the stone was mined or a specific characteristic.
This front of this picture jasper stone boasts an exceptional polish whereas the back has a dull lustre. The terms vitreous and dull describe the way that light interacts with the surface of the stone. A surface that exhibits a vitreous lustre reflects light in a similar way to glass, a dull lustre absorbs light instead of reflecting it. A surface with a dull lustre has an appearance that could be described as matte.
