Description

This is very small specimen – but not for kogarkoite. Kogarkoite is a very rare mineral both at MSH and world-wide. This specimen ihas been analyzed. See the EDS scan. It fluoresces pale blue SW (as it should) and dissolves in water (also as it should). (It is probably not pure kogarkoite, because a small amount of “flaky” residue is left after dissolution.)

Single item shipping weight 2.7 oz. Up to 4 oz, this can be combined with other items for the same postage. Outside the US, this can be shipped in a padded envelope for $7.

Seller's terms and conditions

In addition to the standard terms and conditions, please note the following. Almost all IDs are visual. While in most cases the ID is obvious, there may be cases where it is not. If you are doubtful about a particular ID, please ask for more information. Or do not bid! Similarly, if you are not sure that the specimen meets your criteria, do not bid. I have tdone the best I can with the photos. Nevertheless, if you are not happy with a specimen for any reason, I will refund the bid price – but not the shipping costs (unless the fault is clearly mine) – if the specimen is returned. This policy applies even if analysis of the specimen shows that my ID was incorrect. When in doubt, ask - or don’t bid. Note that most crystals at MSH and Varennes are micros - even if on large specimens. Please pay attention to the stated sizes. Any customs duties, fees etc. are the responsibility of the buyer.
