Description

FOV in the first photo is 6.8 x 4.2 mm. The rinkite is naked eye visible – and you may want to leave it at that. It’s not very pretty. It looks nothing like most rinkite from MSH. Occasionally, good, sharply formed rectangular laths are found. More often (as here) it looks like raggedy bleached lettuce. Partly this is because rinkite in the sill is found mostly in mineralized seams which, while generally more extensive than the miarolitic cavities, are very narrow. The rinkite grows wall to wall and gets shredded when the seam is opened. But even free growing rinkite here tends to be raggedy.

Note: At MSH, all “rinkite group” specimens analyzed have apparently turned out to be rinkite proper rather than mosandrite. Rumor has it the same is true for the Saint-Amable sill. However, Mindat still list both species for this locality - so “group” it is.

Weight 0.9 oz. Actual postage according to total weight.

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.
