Gold (variety electrum) with Erythrite.
JFD19AN5: Gold (variety electrum) with Erythrite
A great novelty of the year 2017. On the slopes of Jebel Taghouni, next to the Taghouni mine, these Gold crystals were found which, inevitably, tend to be small but are interesting for their association with Erythrite, a very, very unusual association. In this piece the Gold is not sensational, but there are quite a few crystals of it and, above all, a lot of Erythrite, so the contrast of that rare association is clear.
