This is not your typical Antero phenakite. What you're looking at is a conjoined twin crystal — two complete, fully terminated phenakite crystals grown together as one. This type of intergrowth is extraordinarily uncommon in phenakite, and finding a twinned pair where both crystals are undamaged and complete is the kind of anomaly that stops collectors in their tracks.
A one-of-a-kind specimen from one of America's most legendary mineral localities. Once it's gone, there won't be another one like it.
