Description

At MSH, lanthanite-(Ce) is a very rare mineral. This is a nice little example. Depending on your taste, the little siderite rhomb that sits in the middle of the “rosette” is either a distraction or an enhancement.

FOV in the close-up photos is 2.0 x 2.0 mm. The lanthanite spans 1.1 mm.

Single item shipping weight (with TN case) is 3.1 oz (88 g). For shipments outside the USA, up to a total weight < 8 oz (225g), this can be combined with other items from this or other auctions for the same postage. If you don’t need the TN case, you can save about 0.3 oz in weight which could be used for something else.

Within the USA, postage for total weights up to 13 oz ranges from $4.25 to $6.50 (including packing etc) regardless of destination. Above 13 oz, I will use “own box” Priority Mail. The rate, including packing, varies by destination from $7.25 to $9.50.

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.
