Specimen # 102112
Mineral: Brucite
Location: Brucite, Killa Saifullah, Balochistan, Pakistan
Size: 3.2 x 2.8 x 2.0 cm


Detailed Description

This is a beautiful aggregate of brucite crystals on matrix. The individual bructe crystal terminations are easy to see without magnification. This specimen is different – it is a discrete disc-like aggregate of crystals on matrix (and fortunately, a bit of the matrix behind the brucite is absent, allowing light to pass through the brucite). The yellow of this brucite has a distinctive greenish hue.

In excellent condition, no damage.

A sweet, colourful brucite.

About These Brucites

The Killah Saifullah brucites were first noted to me by John White after he saw a couple in Munich, 2016. The quality of the finest has greatly increased over those early days. It seems that most of these are occurring in very tight seams, or with a fragmented or brecciated matrix, and so most have contacts and grey spots around them. The colour of most of them is a cream-to-very-pale-yellow, but the best have a bright yellow hue. Many are very finely crystallized, but on some, like these ones, one can easily see many crystal faces. These Pakistan brucites are truly amazing for the mineral.

I’ve done my best to colour-balance them accurately (daylight, shade). I always do that anyway, of course, but I mention it specifically because some mineral specimens are susceptible to really skewing away from daylight appearance when photographed.
