5CN-WLVLondonite-Rhodizite Series

Multiple photos available
05418240014961499597290.jpg
Antsongombato gem mine, Antsentsindrano, Anosiarivo Manapa, Betafo, Vakinankaratra, Madagascar

Dimensions: 41 mm x 33 mm x 39 mm

Good specimen of a very well-defined, pale greenish-yellow crystal of Londonite-Rhodizite on Rubellite-rich matrix. Labelled as Rhodizite, but no chemical analysis has taken place and since both Londonite and Rhodizite do occur on locality, this should be called Londonite-Rhodizite series. Not visible on the picture are several smaller, less well-formed Rhodzite crystals. A very nice specimen from Antsongombato, Betafo, Antananarivo, Madagascar!

Specimen was originally sold by Spirifer Minerals and came to me by Remco Vinken (Netherlands) in 2015.

Specimen is in my personal collection.

Not a very good specimen with Cuprite crystals embedded in Chysocolla-covered matrix. However, you can see the transparency of the larger Cuprites. Crystals are lustrous. There are some bright green spots on this specimen, I think that they are Malachite, but they are not identified. From Mashamba West Mine, Kolwezi, Katanga, Democratic Republic of Congo.
