Spirit diamond

A Spirit diamond is one of the three Summoning spirit gems that can only be obtained from Treasure Hunter. It gives a 40% chance to save a charm when it is worn while creating summoning pouches. It has 40 charges and loses a charge for every pouch it saves a charm for. When all the charges are consumed, it breaks.

As of 22 September 2014, it can now be mined from the gem rocks in the Trahaearn area of the Prifddinas.

Once equipped, it will become a spirit diamond (a) and not stack with other gems in the bank.

Trivia

 * Originally, the spirit diamond was used to store 20 uncharged Summoning pouches; however, this was changed in response to player feedback. All gems obtained before the update can be converted to the current version of that gem.
