@ougeolsoc.bsky.socialThat's hard! Amazing #quartz - so ubiquitous, so many uses - deserves to win #MinCup26 but I have a sneaking fondness for my local minerals. This is an example of the chalcotrichite variety from Old Gunnislake Mine in the Tamar Valley.
So, #teamcuprite join me and vote #cuprite!
@dorabadger.bsky.socialI love a good #quartz but this year I'm #teamcuprite - gotta give respect to the minerals which are so hard to work with, but produce such rewarding results
@naturaelapides.bsky.socialCuprite has the sheen of a very good old burgundy
