6.2 x 4.3 x 3 cm. Classic specimen from Madagascar of large (up to 1.8 cm) yellow Londonite crystals associated with Rubellite. The crystals are exceptional well-formed and large for the species.
5.4 x 4.3 x 4.0 cm. Most newly found and named species are micro-crystals, but this is the exception. Named for University of Oklahoma mineralogy professor, David London, this is the rare cesium-rich analog of rhodizite - and it is a beautiful mineral species, luckily for him! From the co-type deposit in Madagascar, this large, well formed crystal measures 3.0 cm across and is aesthetically perched on matrix. It is lustrous and translucent with a vivid sulfur yellow color. Rare, large, with luscious color, this is an awesome specimen from the collection of Federico Pezzotta.
4.8 x 3.8 x 2.9 cm. A superb combination specimen that includes the very rare species, londonite, the cesium-dominant analogue of rhodizite. A gemmy and lustrous, 2.1 cm, sharp londonite crystal with vivid yellow color sits atop a beautifully contrasting, lustrous, cranberry-red liddicoatite crystal on microcline matrix. It is uncommon to see both londonite and liddicoatite in such richness together in a specimen.
5.0 x 4.6 x 4.0 cm. A fine combination specimen that includes the very rare species, londonite, the cesium-dominant analogue of rhodizite. A large, gemmy and lustrous, 3.0 x 2.8 cm, sharp londonite crystal with pleasing pastel-yellow color dominates a quartz-rich pegmatite vein that includes lustrous, cranberry-red liddicoatite crystals (second photo). It is uncommon to see both londonite and liddicoatite in such richness together in a specimen. The large londonite crystal is pristine, which is uncommon in itself.
4.0 x 3.3 x 3.0 cm. A fine combination specimen that includes the very rare species, londonite, the cesium-dominant analogue of rhodizite. Two gemmy and lustrous, sharp londonite crystals to 1.5 cm with pastel-yellow color dominate a quartz-rich pegmatite vein that includes lustrous, cranberry-red liddicoatite crystals. It is uncommon to see both londonite and liddicoatite in such richness together in a specimen.
5.5 x 2.8 x 1.8 cm. A gemmy and lustrous, 1.6 cm, yellowish-green londonite crystal on matrix from Madagascar. Londonite is the ultra-rare, cesium-dominant analogue of rhodizite. This is a relatively large, unusually gemmy and pristine crystal. Most londonites have some damage. There are several red tourmaline crystals in the matrix.
An excellent, gemmy and lustrous, 1.8 cm londonite crystal with exceptional yellow color on matrix from the co-type locality in Madagascar. Londonite is the ultra-rare, cesium-dominant analogue of rhodizite. This is a relatively large, and certainly unusually colorful crystal. One side of the rear of the crystal is cleaved, but it is certainly not detracting given that the display view from teh front is stellar. There are several red tourmaline crystals in the matrix. 4.2 x 3.7 x 2.9 cm
While not as large or yellow as the next londonite, listed below, this 1.5 cm across crystal, on a quartz matrix, does have the remnants of rubellite crystals for a color contrast. I actually got this from Dave London years ago and it comes with his signed card. 4.9 x 3.2 x 2.2 cm
Usually, a newly described mineral species is but a speck on its host matrix. Not so londonite, from Madagascar, which has been a valid species less than 10 years. In this particular specimen, where the crystal is 2.1 cm across, the translucence, luster, and yellow color on white sugary quartz make this piece outstanding. To boot, this one came out of the personal collection of its namesake, David London. I actually got this from Dave London years ago and it comes with his signed card. 6 x 4.8 x 4.1 cm
2.6 x 1.7 x 1.1 cm. This thumbnail features a translucent and lustrous, greenish-yellow, 2.0 cm londonite crystal on a sliver of matrix. Ex. Dave London Collection.
A yellow, matte luster, translucent, 2.00 cm across, londonite crystal, sits perched on feldspar matrix. The color of this londonite is richer than usual. 7 x 3.3 x 3 cm
A gemmy and glassy, 1.0 cm, pastel yellow-green londonite crystal nicely set in matrix from the Type Locality in Madagascar. Londonite is an ultra-rare cesium, beryllium oxide. 3.0 x 3.0 x 2.2 cm
This specimen shows a very well defined, sharp, glassy, translucent, crystal group of Londonite measuring 8 mm across very aesthetically perched along the side of a black tourmaline crystal. A very attractive and difficult to find association specimen. 2.6 x 1.8 x 1.5cm
