Size Range: 
Cabinet (10-18 cm)
Size: 
5 × 10 × 3 cm
Description

The first photo, a macro close-up, shows the largest xl (11 mm). It is not perfect. A couple of dings are visible under the scope. (One of these can also bee seen on the left edge in the macro close-up.) Most of the smaller xls are in good shape, but some have obviously been contacted.

The specimen is moderately interesting as a micro as well, because there are small, well formed, colorless xls of diopside (?) and prehnite (?). (I’m no Jeffrey expert!)

Weight 5.1 oz.

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.
