Description

Vinogradovite is rare at MSH. This is a very small specimen with one spray of nice crystals of very good color and typical size.

As shown in the first pair of photos (FOV 1.9 x 2.2 mm), the largest crystal is 1.2 mm long. You will need 30X to view it.

It may be useful to see these photos in stereo. Look on Mindat under minID W9W-C91.

Singe item (small box) shipping weight 2.0 oz. For shipments outside the USA, up to a total weight of 8 oz (225 g), this could be combined with other items from this or future auctions for the same postage. If you wish to keep an “open box”, let me know.

For shipments within the USA, there is a nominal increase of about $0.20 for each additional ounce. Above 13 oz I will use “own box” Priority Mail ($8.75).

If desired, this could be sent in a padded envelope, but the postage is the same.

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.
