Simple Opal (Cristobaltite) (ex Josef Vajdak)

Item Description

An odd specimen of Common Opal (Cristobaltite according to the label) from the eastern part of Graham County, Arizona. This piece shows pink to white hues, but the most interesting aspect is that it fluoresces bright green under UV light. This is the only piece of this material that we've had to offer, and it comes with a classic label from Josef Vajdak / Pequa Rare Minerals, which immediately increases the value.
