Unfortunately, production studios do not supply COAs at their auctions. Klingon Time Crystals are rare, naturally occurring crystals found on the sacred Klingon world of Boreth in Star Trek: Discovery. Guarded by the Timekeepers, these mysterious crystals possess extraordinary temporal properties, allowing interaction with the past, present and future. Most famously, Captain Christopher Pike encounters a Time Crystal on Boreth and receives a vision of his tragic future before accepting the crystal to help the USS Discovery. They have a distinctive blue-green crystalline appearance while the props themselves were either coloured resin or clear resin illuminated by green LEDs. This item is a medium clear resin time crystal confirmed by the prop maker in charge of making the crystals as being used in the seminal S02E12. The only other time crystal props that we are aware of that have entered the secondary market are from a single large crystal lot, the items from which have yet to be made available. All components of this item are from the production. Price is for ONE item – please indicate which you would like. Series/Production: Star Trek: Discovery. Type: Time Crystal (Large). Dimensions: Approximately 7-9 inches. Important note on screen use. Unless otherwise stated, we are not claiming this item is screen-matched to a specific episode or scene.
