TP27Z1: A novelty at Tucson 2014. These Opals (variety hyalite) appeared for first time during the Tucson Show and in addition to the fact that they are gemmy and quite aesthetic, standing up on their matrix, their main feature is that they fluoresce even in daylight! In fact, they fluoresce in almost all kinds of light, neon light, LED light, daylight and, of course,UV light. The only light with which they don't react is incandescent. As they are so new the locality is still very vague, sorry for that, but we are sure that time will clarify the locality as well as the reason why they fluoresce so strongly.
This specimen was photographed and published as a novelty at the 2014 Tucson Show in the magazine "Lapis" number 03/2014, page 32, and in the Russian magazine ‘Mineral Observer’ on page 62 in the volume 19, number 3
