Description

This is a micro. FOV in the close-up photo is 6.7 x 4.0 mm. The photo shows fibrous white niveolanite on the left, powdery white dawsonite on the right, and pinkish fragments of unaltered petersenite-(Ce) in the center. You will need 15X to view these clearly. The matrix is microcline with a bit of aegirine and analcime. The white niveolanite and dawsonite don’t show up well in the macro photo due to lack of contrast.

Weight 0.4 oz (including TN case). Single item shipping weight 2.4 oz. Up to 4 oz, this can be combined with other items 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.
