Description

Small but pretty pale blue leucosphenite xls with pale yellow/green calcite on massive pectolite from marble xenolith – a somewhat unusual environment for this mineral.

You will need 20-30X to view the xls. FOV in the main photo is 3.0 x 1.7 mm. The largest xl (top center) is ~ 0.9 mm. However that xl is not well lit in the photo – the smaller xls show up more clearly. The xl can be (barely) seen near the center of the cavity in the macro photo.

Weight 0.2 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.
