Jasper Mineral Group: SILICATES
|
| Jasper is an opaque form of
quartz with fine grains known as chalcedony.
Chalcedony is also known as cryptocrystalline
quartz. Jasper is easily identified by its red, yellow and brown colours. Because it is a quartz, it takes a fine polish and often stands out as a smoothly tumbled pebble in streams.
When jasper has patterns made by the different colours, it is often given a fanciful name. The name often times described what the pattern looks like and is representative of the kind of jasper found in a certain location.
