Sterling Mine, Ogdensburg, Sussex County, New Jersey, United States of America
Size Range: 
Thumbnail (1-3cm)
2.5 × 2 × 2 cm

Chlorophoenicite fibers to ~ 1.7 mm. The Franklin and Sterling Mines remain the only know non-slag localities for chlorophoenicite. Chlorophoenicite is not as rare as some of the other arsenates found here and this is just a small sample. But it is rarely available. The chlorophoenicite has been EDS verified on another specimen. In addition to a few small (~ 2-4 mm on edge) rounded franklinite crystals, there are a few very sharply formed octahedral crystals some with penetration twinning!) in the cavity with chlorophoenicite. They might be secondary franklinites or perhaps - as suggested by the twinning - hetaerolite. I don’t know, so I’m not claiming either. Just an intriguing small bonus. The chlorophoenicite vug has a rim of colorless willemite and there is a vug with larger (but not well terminated) willemite crystals djacent. Note: The mine was closed in 1986. This material was recovered by the Sterling Hill Mining Museum in about 1992 and found on the dump in 1993. The mine is now flooded nearly to ground level.

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.
