There have been a number of official and semi-official releases*, many with very little documentation. The following are in date of release order.
*A “release” means the bead was available to collectors – so I haven’t included limited edition beads such as the stripey Beaverbrooks bead (which was made by the Trollbeads beadmaker Sue for all Bristol Beaverbrooks staff in the store colours of grey, purple and white at their TB event, May 2014).
