Description

Stilbite with laumontite from a classic zeolite locality. As is typical, the laumontite is crumbling apart. There are only a few euhderal crystals left. To compensate, there is some interestingly weird platy babingtonite with “byssolite”. This is shown in the second pair of photos (FOV 4.3 x 6.5 mm).

Note: This is “byssolite". i.e. “Amphibole Supergroup (Var: Byssolite”) – not necessarily actinolite.

Single item shipping weight 5.8 oz. For non-USA destinations, up to a total weight < 8 oz, this can be combined with other items for the same postage.

Within the USA, postage now varies by destination. For total weights up to 13 oz, it ranges from $5.00 to $7.00 (including packing etc). Above 13 oz (up to 16 oz), I will use “own box” Priority Mail. The rate, including packing, varies from $8 to $10.

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.
