Sussexite is a very uncommon mineral. While it is know from more than a dozen localities, only a few have produced specimens with Mindat photos, and large specimens, such as this one, are only available from the Franklin and Sterling Hill ore bodies. (The co-type localities are all various openings in the Franklin ore body. The Sterling Mine, which this is from, is not one of the co-TLs.)

At Franklin and Sterling Hill, sussexite has two very different habits, fibrous (generally white unless stained) and cherty (generally pinkish to purple). It can be hard to believe that these two manifestations are the same mineral. This specimen features the fibrous variety. 

In addition to a couple of full-view photos, I have provided a micro close-up (FOV 6.9 x 4.4 mm) of a small sample of the sussexite fibers. The matrix is lean franklinite/willemite ore in very weakly fluorescing calcite.

This is a “near-museum-size” specimen. Unfortunately that means that postage for non-USA buyers will also be “near-museum size”. For USA buyers, things are not so bad. I will use a medium USPS Priority Box. You could even stuff in additional items for the same rate.

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.
