Lime Crest Quarry, Sparta Township, Sussex County, New Jersey, United States of America
Size Range: 
Thumbnail (1-3cm)
2 × 1 × 0.8 cm
Largest Crystal: 

A doubly terminated xl ~ 1.3 cm long. Not large for this quarry, where xls reach 3+ cm, but a decent size. Under the scope, there is some obvious damage. It is not noticeable when hand held, but it does show up in some of the macro photos. These xls are even more fragile than franklinite. For norbergite from the Franklin marble, this is actually in relatively good shape. It is also relatively sharply formed,

The xl fluoresces bright yellow. The latest consensus of Franklin experts is that that is a good indication that this is norbergite rather than chondrodite. (But the material has not been analyzed.) However, the color in the UV photo (#2) is only an approximation. My camera wants to make it look somewhat green, whereas with the naked eye I see a fairly pure yellow. The photo is a compromise between what the camera things it sees and what I think I see.

The fourth photo shows the most damaged part of the xl. It is also strongly side-lit to show a bit of translucency.

The fifth photo is the “back”. The last photo is a micro photo attempting to show that the top termination is in good shape.

Weight < 0.1 oz. Not suitable for shipping in a padded envelope. Single item (small box) shipping weight 2.1 oz. This could be combined with other items, up to a total weight < 4 oz, for the same postage.

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.
