It always rains when we are here... ! Not much has changed since our last visit in 2006... The interesting Coelestin-zone in "layer 7" is still being worked on and exposed, but there are not so many hollow Coelestin-cavities. Most of the material is massive. No blue Coelestin-xx also. But we found Sphalerit-xx in "layer 13". More info is in our forum...

The Winterswijk quarry is worldfamous in the Netherlands ;-) for it's nice crystals of Pyrit, Calcit, Coelestin, Strontianit, Sphalerit, Galenit und Markasit. The biggest self-collected blue Coelestin from here is 3 cm in length (and proudly standing up on the matrix ;-) and contains small needle-formed Pyrit crystals... Usually the Coelestin is white to reddish (from Fe-oxides from the above layer). The Strontianit is always grown on the Coelestin.
The layer in which the Coelestin is found, is about 30 cm - 1 m thick, just under the thick red layer, and is usually very well visible in the quarry.
Maurice de Graaf and Diederik Visser visited the quarry on 05-09-2003, found only few Coelestin, but lots of massive Calcit ;-) Only 2 of 100 Calcit-'knauers' had a cavity, most were massive...
Mark and Niels Phillippeau visited the quarry in november 2004 and found Pyrit, Calcit, Coelestin, Strontianit, Galenit and Sphalerit! We visited the quarry on 01-04-2006 and found Calcit-xx, Coelestin-xx, Strontianit-xx and of course some Pyrit-xx with the Coelestin...
