Description

Largest xl ~ 9 mm (second through fourth photos). The xls on this specimen are not as large as those from Flora Mt. (Lovozero). But, unlike most Flora specimens, the xl here are grow freely in open cavities and there are several of them on the specimen, including some small ones (first and fifth photos, 2.1 and 2.3 mm resp.), which are translucent and have a beautiful red-brown color when properly illuminated. You will need 10-20X to view the smaller xls.

The matrix is pinkish feldspar with contorted natrolite (?) and aegerine, both as green acicular xls and as larger, terminated xls.

The label is not more specific than “Khibina massif”.

Weight 5.1 oz. Single item shipping weight 7.1 oz. Up to a toatal weight <= 8 oz, this can be combined with a small item for the same postage.

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.
