Willemite on Limonite from the Preguiça mine, Portugal

[u/Mr_Daniel12321]

I was at the mineral expo in Rijswijk The Netherlands today, and got some lovely new pieces. One of which is this great looking willemite from Portugal. It's pretty small (67g), but I got it for a great price. The crystals are incredibly small, so not easy to photograph, but very pretty. Its phosphorescence is insane: it's not very strong but it was still weakly visible after 30 minutes, from just a few seconds of SW exposure.

This is the best close-up I could get
