There is also another one to the left of the small "invisible" crystal. It is a shorter but wider crystal.

Could be an epimorph I guess? - I have one from Castleton, Derbyshire which is a fluorite epimorph of a coral fossil

People do seem to mix the two terms (epi and pseudo) up

Beautiful symmetric agate, the colour scheme reminds me of the ones from the famous German agate locality of St. Egidien in Saxony. (Or, for those who like Lord of the Rings: It's also slightly reminiscent of the Eye of Sauron ;-))
