Description

Well terminated vesuvianite prisms. The very elongated habit is characteristic of MSH. Many of the prisms impale water clear pseudo cubo-octahedra of apophyllite.

Under the right lighting, these prisms can be very pretty under a scope. You will need 10-15X. FOV in the first two photos is 4.4 x 6.3 mm. FOV in the third photo is 7.1 x 4.5 mm and about 17 x 15 mm in the fourth photo. This photo also shows some of the pther – more blocky - apophyllite xls on the specimen. One of these crystals even has a tiny tuft of embedded tuperssuatsiaite or raite.

As shown in the full view photo, the vesuvianite is naked eye visible, but you really need a scope to appreciate the vesuvianite. Under the right lighting, these prisms can be very pretty. You will need 10-15X

Single item shipping weight 6.8 oz. If combined with other items, there

Single item shipping weight 6.8 oz. If you are planning to hold an "open box" so as to reduce postage costs by combining items from a future auction, please note that USPS postage rates recently changed significantly.

Outside the USA, the stated postage and packing rate applies up to a total weight of 8 oz (225 g). It is no longer possible to save on postage by using a padded envelope.

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 $8.50 (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.
