I’ve added some excellent yellow stilbites on the website in the new Mali Update (click here).

Beautiful yellow stilbite balls from Mali made their debut at Ste. Marie 2014. Although there has only been a small trickle of fine specimens since then, the deposit at Diamonkara has now once again produced a number of very fine pieces. As in 2014, moderate-to-significant damage was almost ubiquitous, and high-quality specimens like the ones in this lot are very uncommon. As a side note, although there has been a push to sell these as specimens of stellerite, none of the analytical work done to date has confirmed any stellerite identification, to my knowledge (and I am aware some analytical work has been done).

As for the specimens themselves, the good Diamonkara pieces are absolutely some of the nicest and most distinctive stilbites I’ve ever seen from anywhere, with beautiful colour and form. They are perhaps not yet appreciated for what they are – these are striking, colourful display specimens of a mineral that is often pale and drab.

This Mali Update – October 2014 (click here) includes unusually fine balls of radiating green prehnite perched upon sharp, lustrous blocky epidote crystals. The specimens from this particular recent find are better defined and nicer than the typical ones from here. Also in this update are two more of the great yellow stilbites from Diamonkara.

Beautiful new specimens from Mali, featuring yellow balls of stilbite crystals from Diamonkara, a new find. The Diamonkara workings are in the same general vicinity of the Arrondissement Diako which has produced the now well-known specimens of prehnite and epidote. Also new among these specimens is an exceptionally fine prehnite on epidote.  These specimens are now posted under Mali – July 2014 Update (click here).
