New World Update 27 May 2022

27 May 2022

CAN you believe it, another week has flown by and we end it with a further selection of minerals from around the World. These build on the various localities we have visited over the last couple of weeks and include many aesthetics and some quite rare species. Let’s cut straight to the chase and see what’s on offer.

In no particular order we’ll start with a particularly nice Cassiterite with Scheelite and Muscovite from Mount Xuebaoding in Sichuan Province, China. Although far from expensive, it packs a lot of punch with its perfectly developed, lustrous jet-black Cassiterite crystals forming the majority of the specimen. Surrounded by silver-white clusters of Muscovite mica plates, most with a very pale greenish tint and a few pale lemon Scheelite crystals, this is a beautiful small cabinet specimen. The specimen’s weight alone tells you it contains one heck of a lot of tin!

Two of today’s much rarer species are Perraultite and Kupletskite from the gem pegmatite deposits at Volodarsk-Volynskii in Ukraine. Admittedly a reference specimen, these two species are embedded in a fine granular complex granite, more aplite than pegmatite.

For fans of the British science fiction series Doctor Who we have the perfect specimen. From the Moscona mine in Asturias, Spain, lemon yellow Fluorite crystals are overgrown by chains of interlinked pure white Dolomite crystals. The Fluorite forms cubic crystals of a uniform 3 to 4 mm on edge and despite these sounding so small, they are deceptively well defined and look much larger! Not that I’m implying they distort the spacetime continuum in terms of relative dimensions but honest, they do look bigger! All the Fluorite crystals are gemmy to translucent with a bright glassy lustre while the individual blades of Dolomite can attain 1 cm and display characteristic curved saddles with a pearlescent lustre.

The Allchar deposit at Rožden in the Republic of Macedonia is famous amongst collectors for its rare thallium minerals and I know a few people who have fine suites from here. We have a Parapierrotite with Realgar, Parapierrotite being a thallium sulphosalt, with Rožden its type locality. The Parapierrotite forms in clusters of metallic, greyish-black micro-crystals in a matrix of blood red to bright scarlet Realgar with small orange patches of Orpiment.

If a really pretty miniature takes your fancy, take a look at the Baryte with Quartz from Cavnic in Romania; a specimen all about inclusions! Thin bladed crystals of lustrous Baryte measuring to 2 cm are heavily included with bright orange Realgar while retaining a surrounding halo of colourless, transparent Baryte. These sit over Quartz crystals to over 3 cm tall, included with a dark grey sulphide. The fine contrast between the colourless and bright orange Baryte and the Baryte against the dark Quartz makes for a striking miniature.

Our Magnetite from the Aosta Valley in Italy is somewhat unusual because it actually forms as cubic crystals. Yes, I know it is in the cubic (isometric) system, but commonly Magnetite forms as octahedral crystals. This is a great specimen with crystals averaging 8 to 10 mm on edge with some exceeding 1.2 cm, frequently a little elongated, slightly curved and with a brilliant, black metallic lustre.

Other cool and tasty items include a Scheelite crystal on Dolomite and Quartz from Baia Sprie, Romania; Amethyst Sceptre Quartz crystals from Samnam-myon in South Korea; large Spinel and Diopside crystals from the Gon phlogopite deposit in Russia; a strikingly coloured turquoise-sky blue Hemimorphite from Dognecea, Romania and a lovely pair of Aquamarine crystals with Muscovite from the Shigar Valley in Pakistan. The Beryl prisms in this specimen are tinted somewhere just on the cusp between blue and green, at a watershed of colour, so they may be perceived as either very pale blue or green, but are designated Aquamarine, nonetheless.

I also feel compelled to just mention a deep citrus apple-green Adamite from Lavrion, Greece; fine Almandine Garnets from the Monteneve mine in Italy and a beautiful Pyrite with Siderite from the Trepča Complex in Kosovo. Omitting these would have been rude.

Let’s end with a Galena from Herja mine in Romania. I think I can speak for most collectors in saying Galena displaying a ‘melted’ look, so characteristic of Bulgaria and Romania, makes for stunning specimens. Today’s cabinet specimen is particularly gorgeous, displaying flowing curved edges and corners with a brilliant, glistening metallic lustre and super-smooth surfaces, making it appear more like liquid mercury than a crystalline solid. I could go on waxing lyrical, but just take a look as a picture paints a thousand words.

Set some time aside over this weekend to deliberate over today’s selection, with the ever tempting prospect of relocating a few to your own collection.. PT
