I’ve added some super new specimens in this Elmwood Update (click here). This update features beautiful high-quality twinned calcite crystals, and also a great fluorite.

First opened in the 1970s, the Elmwood Mine (the Elmwood-Gordonsville-Cumberland mining complex) has produced some of the world’s finest calcite crystals, many of which are twinned. Over the years, the miners referred to the large orange Elmwood calcite crystals as “footballs”, and they referred to the clear gemmy calcites in this update as “jewels”. These are from a pocket found a few years ago. Most specimens were damaged and these are exceptional – the handful of top-quality specimens in this update are the result of a quest through many flats.

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.

This Democratic Republic of Congo Update (click here) features fine azurites from a new find at Kibwi, an excellent primary malachite from the Tantara Mine and deep pink cobaltoan calcite from Kolwesi.

 Azurite, Kibwi, Katanga, Democratic Republic of Congo – 4.3 cm

Although the copper deposits of the Democratic Republic of Congo have been famous for a long time, excellent crystallized azurite specimens are uncommon from the DRC (and have often been quite expensive). This lot is from a new find at Kibwi, located approximately 70 km northeast of Lubumbashi on the road to Likasi in Katanga.
