PostPosted: Feb 04, 2019 20:13    Post subject: wrong locality given for botryoidal fluorite?  

my friend is currently at the tucson gem show. she recently acquired a flat of lavender purple botryoidal fluorite with satin-luster, which the dealer told her are from inner mongolia. a quick search tells me that the botryoidal fluorite coming out of inner mongolia has been a very dark indigo and often appears in conjunction with quartz. fluorite that looks more like this specimen (pictures attached) seem to be from the minggang mine in henan province, china.

could someone confirm that my suspicions about wrong locale are correct or not?

Almost certainly CHINA. If you google "purple botryoidal fluorite" many similar and nearly identical examples come up on different dealer/auction websites, all of which give China as the basic location.

Mingang seems right.
Minggang Fluorite Mine, Shihe District, Xinyang Prefecture, Henan Province, China

Looks like good material. It came out about 10 years ago, but maybe some new material has come out.

Volkmar, While you are actually correct, we are not talking about political boundaries or governments here. We are talking about mining and mineral specimen localities.

Whenever I have seen the dark indigo blue fluorites, their locality has always been listed as "Mongolia" or "Inner Mongolia". I have never seen them as coming from "China" or something like "Mongolian part of China" or something like that.
If you or anyone else has seen a label with "China" on it, for those fluorites, please post it here for a reference. Thanks, Bob
