Cerro El Grillo Reverse Scepter Thundereggs
One of the more outlandish mexican thundereggs that I have seen comes from a secret location in the Cerro El Grillo mountains. Like many of the mexican specimens it tends to form hollow geodes with crystal, but in this case the crystals are prone to reverse scepter amethyst. Amethyst thundereggs = rare. Reverse scepter amethyst = rare. Reverse scepter amethyst in thundereggs = phenomenal. This location is a fairyland!
