Large South Dakota Jaspers

This is an extra nice selection of South Dakota Jaspers.  Some are small Prairie Agates and some may be large Bubble Gum Agates.  These range in size from  2" to 4" and will be great for those out there with larger tumblers or stone cutters.  While some may have a broken edge or side, most of these Jaspers will be complete, rounded and smooth nodules making them easier to coarse grind than round broken material.  Approximately 3 nodules per pound.  Limited supply so don't delay!

bubble gum agate

Bubble Gum Agate

This is nice mix of sizes of South Dakota Bubble Gum agates.  These are round bumpy jasper nodules, often times made up of two colors of jasper combined, making them appear like spent chewing gum.  These Bubble Gum agates are sized from 3/4" to 1 1/2".  Once abundant in the South Dakota Prairies, they are getting harder and harder to come by.  While there will likely be a few broken ones, the majority of these are rounded by Mother Nature which makes for an easier than normal roughing stage in a tumbler.

The term "shungite" was originally used in 1879 to describe a mineraloid with more than 98 percent carbon. More recently the term has also been used to describe shungite-bearing rocks, leading to some confusion. Shungite has to date mainly been found in Russia. Shungite has been used in medical treatment since the early 18th-century. "Peter the Great" set up Russia's first spa to utilize the water purifying properties of shungite and instigated its use in providing purified water for the Russian army. The anti-bacterial properties of shungite have been confirmed by modern testing.

Shungite is considered to be full of health benefits due to the natural fullerenes found within it. It detoxifies, acts as an anti-inflammatory, is antibacterial and antioxidant. Shungite protects against EMF frequencies and is fantastic to have near computers. Some even sell small flat pieces specifically to attach to cell phones and laptops. Shungite is being touted as a must have for those suffering from electrosensitivity. It is also said to rid negative emotional patterns.
