Description

Annite is moderately uncommon at MSH. It is not the only “biotite” mica at MSH and could be confused with dark phlogopite or siderophyllite in some environments. This is an analyzed specimen. (See the “Analysis” tab.)

The largest crystals are ca 8 mm in diameter.

Single item shipping weight (no case) is 3.7 oz (105 g). Outside the USA, the stated postage and packing rate applies up to a total weight of 8 oz (225 g). If you wish to combine with items from future auctions, you must let me know.

Within the USA, there is a nominal increase of $0.20 for each additional ounce. Above 13 oz, I will use Priority Mail. Up to 16 oz, the “own box” Priority rate is $9.25 (including packing). .

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.
