As you may have seen in my Tucson blog post, a recent find at Orange River, South Africa has produced some beautiful quartz crystals with exquisite sharp red phantoms. I’ve posted them in this Red Phantom Quartz Update (click here).

Red quartz has been produced from this locality for many years, however, long-time South African dealer Clive Queit told me he has never seen any he liked as much as the ones from this 2016 pocket, because these have such distinct red phantoms enclosed in sharp, clear quartz crystals – in his view they are the best.

I’ve posted a new Brazil Update (click here), with superb, diverse specimens.

From the world famous morganite finds at the Urucum Mine, this crystal is likely from the 1973 pocket.

A one-of-a-kind specimen, this aqua-colours montebrasite crystal was found in a pocket in the 1970s. Most of the pocket material was etched and did not exhibit crystal faces.

From a new recent find, a small pocket at Novo Horizonte produced a small number of remarkable crystals, sold to me under the label “synchysite”. Subsequent analysis by Don Doell has confirmed more about their identity. Having conducted semi-quantitative EDS at SGS Labs, Don found that these are in fact phosphate mineralization, and they are likely a combination of rhabdophane-(La), rhabdophane-(Ce) and possibly including monazite-(Ce). They appear to be pseudomorphs after a REE carbonate, probably in the parisite group, given that parisite-(La) has been found at Novo Horizonte in crystals with a similar aspect and appearance, at a similar time. They could also be after bastnasite-(La), which has been described from the locality. For now, I’m labelling them rhabdophane, pseudomorph after parisite, with the proviso that the above is the technically closest identification information to date. Thanks very much to Don for this analysis!

I’ve added a selection of fine, distinctive specimens in the new China Update (click here). The pieces in this group are very high quality, picked from many different lots. There are beautiful fluorites of various colours and habits, including stunning clear crystals, deep blue, green, purple, and there are great phantoms and zoning in some of them. The update also includes a great pyromorphite, an unusually fine quality Xiefang golden barite (these are virtually always damaged) with a nice phantom, a super cabinet specimen of Shimen calcite with a large twinned crystal, excellent lustrous spessartines and more.

This Russia Update (click here) features a small number of excellent specimens from the famous mines of Dal’negorsk. Some are relatively recent and some are older, having resided in collections until now. The fluorites in this update are particularly beautiful examples of different combinations of crystal forms and the calcites are brilliant with clarity and internal play of light. The galenas are textbook twins (on the spinel law), the axinite-(Mn) is a remarkable high quality cabinet specimen and the ilvaite is super, particularly given how hard it has become to obtain the decent-sized Dal’negorsk ilvaites. Finally, the sceptered beta quartz specimens are aesthetic, high-quality pieces from the 2013 find.

I’ve added a new Morocco Update (click here) with some particularly fine specimens. I have managed to obtain five more blue barites from the Sidi Lahcen Mine in Nador that are worthy of including on the site. Although almost all barites from Sidi Lahcen have some amount of damage (many are badly damaged) these ones are in excellent condition – they are great high-quality pieces.

This update includes several wonderful individual specimens. A startling hot pink cabinet specimen of cobaltoan dolomite from Bou Azzer, a super sharp thumbnail-sized specimen of, and also a great glassy miniature of green fluorapatite from Imilchil, a sharp, gemmy brown titanite from Imilchil, a Tounfit fluorite that will have you looking a while to sort out the morphology, and an unusually fine specimen of sprays of goethite crystals included in quartz crystals from Tizi-n-Tichka.

Finally in this update, I have included a group of new specimens of yellow fluorite cubes with barite and quartz. Although Moroccan yellow fluorite is often attributed to “Aouli”, an abandoned historical mining complex which is not producing specimens, contemporary specimens are in fact from an area near Sidi Ayed. It is road-accessible, but it is relatively remote in a barren, windswept area, which sees sandstorms in the dry weather and roads washed out in the rain. These fluorites are nice for Sidi Ayed specimens, for a few reasons – they are isolated on quartz crystals rather than massed together, some of the quartz has some nice red colouring from hematite, and a few of the crystals show tiny irregular zones of greenish blue colour.
