Description

This is a micro. The bright canary yellow ball of zakharovite in the center of the main photo is ~ 1¼ mm. The orange eudialyte xls are ~ ¾ mm. You will need 15-30X to view them. The villiaumite is the dark red-brown blob on the right. It is etched and anhedral. Villiaumite is uncommon in the sill, but in this find it was fairly abundant. No euhedral xls were observed. The grainy zakharovite was verified at the EDS level. Eudialyte from the sill has many colors. Orange is common. (But only eudialyte proper has been reported from here.) The green “urchin” next to the zakharovite in the center is aegirinite. This habit is common here. Weight 0.2 oz. This could be mailed in a padded envelope for $7 (less in the USA).

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.
