This is a dramatic cluster of large gmelenite crystals featuring a giant 3 cm crystal in the middle, all of which have replaced chabazite. The luster is unusually good on this piece, almost glassy and therefore far better than on others I have seen in the past! This is new material collected recently from this classic old locality that is difficult to access, by my friend Rod Tyson (a semi-retired mineral dealer and well-known Canadian field collector!). This is a significant piece, from what I have seen in the past and also in context of this new find, for overall size and quality.
