| A quite typical Uffeln specimen. However, one has to understand that Uffeln produced excellent rock crystals and smoky quartzes in alpine quality up to 25 cm...

Quite typical doesn't mean that it can't be very nice ;-) And a double-terminated, clear quartz on matrix, even if only 4 cm small, can be considered very nice! If only the largest and the best specimens would count, we wouldn't enjoy many minerals except for the MIM Museum in Beirut or the private collection of Adalberto Giazotto ;-)

Germany is actually not known for large stibnite crystals, here's a rather good one from North Rhine-Westphalia:

| Probably the best German stibnites from there... Regarding your mindat list post: the mindat list is - by far - not complete. There are roundabout 1900 different mineral species known from German localities. However, you´re right. There are new species found every year...

Wow, even 1900? Any reliable source for this?

| Me;-) Maybe about 50 species are doubtful in this list. Many of those 1900 species have never been published, of course.
