Collinsite from this locality, according to MINDAT, is said to have its orgiins in large deposits of guano, or bat poop. This is a classic find for the study of such origins, apparently. The collinsite here is in light brown, fibrous aggregates associated with fluorapatite on andesine. Also in association is "wurtzilite", now known as asphaltum, a natural hydrocarbon mineral more commonly referred to perhaps as "tarry goo."

MCW57 - Collinsite - $ 750
Rapid Creek, Yukon, Canada
small cabinet, 6.2 x 5.5 x 3.9 cm
ex. Ian Nicklin

Sorry, we have no images of this specimen at present.
Small Cabinet, 6.5 x 5 x 4 cm This specimen features a 2 cm radial pinwheel of collinsite tucked safely against contrasting matrix, which helps to bring out a pale greenish color to it as well. This remarkable collinsite specimen was one of the best for its size from Rod Tyson's stock many years ago when it was sold to Ian Nicklin, in whose collection it has resided until recently. This important Canadian collection was brought to the show and sold this year (I have another 4 dozen mixed specimens to appear later, so stay tuned!). Coincidentally, Rod was marketing simultaneously small specimens (most were thumbnails) of similar collinsite from a RECENT find of the stuff, and I think that contributed to pricing this one lower by a factor of two than it might have been a year ago. So, there IS more out, but not in larger specimens of this calibre, making it a relative bargain for now. (I will post the smaller pieces from the recent find, shortly)

MD-177430 - Kovdorskite, Collinsite - - Archived
Kovdor Mine, Kovdor Massif, Kola Peninsula, Murmanskaja Oblast', Northern Region, Russia
miniature, 4.1 x 2.4 x 1.5 cm.

4.1 x 2.4 x 1.5 cm. This splayed cluster of cream-colored, lustrous, glassy kovdorskite crystals flanked by sparkling druse of collinsite behind comes from the huge alkali massif on the Kola Peninsula. The longest crystal is 3.75 cm and thus near the record size of the species.

A very little-known hydrated phosphate, collinsite is (rarely) found in fissures at Rapid Creek along with lazulite. Most worldwide occurrences of this mineral are as radial fibrous balls embedded in matrix, so actual crystals are quite rare. 1.7 x 1.3 x 1.2 cm

This splayed cluster of cream-colored, lustrous, glassy kovdorskite crystals flanked by sparkling druse of collinsite behind, comes from the huge alkali massif on the Kola Peninsula. The longest crystal is 3.75cm and thus near the record size of the species. While not from the 1980-ish type find here at this locality, this specimen is from a noted later find of the late-1990s that produced, in a small pocket the size of a basketball, the largest crystals of the species. A faint telltale blue hue, proves this (in the middle of the specimen, you can see it in the photo - there is a blue zone internally, visible from the backside), and was characteristic of that pocket. It is quite nice for the size, and somewhat more aesthetic in person. That being said, it is unarguably more aesthetic than almost any other but a few examples of this species, that could be had, the crystals are large, and the species is significant on its own merits.
