We have been part of the Wheel of Time family since 2005 and some of us here at Badali have been fans since the beginning in 1990. All of us here have a special and important place in our hearts for the Wheel of Time Universe and the people and fans associated with it, which is why it is with heavy hearts we tell you that the Wheel has turned and our license with Wheel of Time is coming to an end. As of April 28th 2019, we will no longer be allowed to make any new jewelry, but we will be selling the remaining inventory until October 2019. If there is something you have had your eye on, now is the time as we will have limited stock of everything.

Some of their bestselling items were the Aes Sedai Great Serpent ring, their Asha'man pins, and their foxhead medallion. 

Dragonmount has been a long-time reseller of their products and we're sad to see them shuttering their line of quality goods.  The reason for the shutdown is related to their license expiring and now being held exclusively by Sony (and potentially Radar Pictures and Amazon Studios, although those details aren't clear at the moment). There's a possibility that a new license to produce these products will be granted in the future, but only time will tell if that happens, or if the same products will be re-released if it does. 

Make your orders now at Badali Jewelry website, and look for their remaining inventory through October 2019.
