Kialara 2015 Labyrinth "Ruby Edition"
|Material||Stainless Steel, Glass, Ruby|
These were made in 2015 but were unreleased until 2018. The original idea for the Labyrinth was to use artificial rubies as the balls in the maze, however they were not as red as Kialara hoped so they were never finished.
They are serialised XX/250 but only 20 were made.
They are currently being auctioned on the bitcointalk forums.
