A wonderful combination, red "ruby blend" sphalerites are just lovely, especially when combined with yellow fluorites.

Besides that, I have some small doubts concerning the locality (but I'm not the greatest expert on Weardale, maybe Jesse Fisher can help here):

I have never seen yellow fluorites from Frazer's Hush, only purple, green and grey ones. I also don't remember such red and gemmy sphalerites from that area, but this is just my humble opinion as a fan but not expert of Weardale fluorites.
No idea if Frazer's Hush maybe produced such pieces and if I'm maybe completely wrong. I know this wonderful combination of gemmy red sphalerite and yellow fluorite from Freiberg, but I have never seen it from Weardale or from somewhere else in England. That's why I mention this, it's just a small doubt and maybe I'm wrong. Weardale often surprises, one pocket of fluorite can have a completely different colour than the one next to it.

Regards
Tobi

Thanks Tobi. I was a little skeptical as well on the locality, but I thought I would put it out there to view and get feedback.
