Description

This is a lot of two specimens of catapleiite of very different habits. One specimen has a large crystal ca 2 cm in diameter. The dimensions given are for this specimen. The other specimen is a catapeleiite “rosette” ca 1.1 cm in diameter. Overall, this specimen is 1.0 x 1.1 x 0.7 cm in size. It is shown in the first pair of photos. (Note: The specimen will appear to be somewhat darker when hand held. It is best appreciated under a scope with reasonably strong lighting.)

The last three photos are for the larger specimen.

The main xl is 2 x 1.5 cm. It is lustrous and well formed. But it has a smooth contact on one side. But it isn’t broken – it just grew this way. Contacted or not, single crystals of catapleiite of this size are not common.

The last photo shows a smaller (~ 5 mm) xl attached to one edge of the main xl.

Combined shipping weight (no case for the larger specimen) 3.5 oz. Outside the USA, the stated postage and packing rate applies up to a total weight of 8 oz (225 g).

Within the USA, there is a nominal increase of $0.20 for each additional ounce. Above 13 oz, I will use Priority Mail. Up to 16 oz, the “own box” Priority rate is $9.25 (including packing).

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.
