If you are reading this then your are probably already captivated by the gorgeous color of this beautiful Pederneira tourmaline! The purplish red that is the main color here is topped with a gemmy blue zone on both the main and the side crystal! The flat termination again has a thin purple layer which is very much unusual and dazzingly appealing! With a length of 9 cm this is a dramatic eye-catcher of good size and very high quality!

This opal specimen is out of a unique 2014 find that yielded a small number of these rare opal variety. The striking turquoise Paraiba-color is caused by copper and catches the eye instantly. Analysis identified this mineral as the extremely rare tridymite crystobalite opal.The opal is grown over colorless quartz and rock matrix. Admittedly the specimen shows some damage but the outstanding color and the sheer rareness of this mineral more than make up for this little deficiency. A beautiful piece of natural aesthetics and strong color!

HR594 - Rhodochrosite - Sold
N'Chwaning Mine, Kuruman, Kalahari manganese field, South Africa
Size: 9.5 x 7.4 x 7.1 cm
Watch Video

This rhodochrosite from the N’Chwaning Mine is a brilliant piece with crystals up to around 1.3 cm. Especially attractive is the striking contrast between crimson red rhodochrosite and the metallic black background of the characteristic manganese matrix! The crystals are gemmy, lustrous and sharp and largely in best condition. Only some peripheral crystals are broken but which is hardly visible and almost unavoidable on rhodochrosite specimens of this habit. I stabilized a visible crack at the matrix’ bottom but it is definitely not repaired! A brilliant piece from this famous locale!

Several isolated bornite crystals of dark purplish color are perched on a beautiful quartz studded matrix. While some of the crystals are sharply defined, some others are overgrown by a second bornite generation. The whole piece is without damage down to the smallest quartz crystals. At closer inspection the color is much more divers than seen at first glance. Grey gives way to intensive purple, golden, brown and blue parts. Very attractive and well developed overall!

Watch Video

Good crystallized rose quartz is a Brazil-exclusive thing and this fine specimen is no exception. It’s a strikingly beautiful structure of rose quartz crystals in very different sizes and shapes that makes the all-quartz specimen look like some vivid piece of art. From layers of solid quartz covered in fine micro-crystals to larger well defined prisms this specimen holds a fascinating variety. The quartz is all great luster and intensive color on a sweeping shape! The backside is totally flat as it seems to have been grown on some kind of crystal, probably feldspar as there is still some residue visible. Size and quality of this rose quartz specimen are absolutely stunning and very much elegant in person!

VI259 - Epidote - 2600€
Ras Koh Mts., Kharan, Balochistan, Pakistan
Size: 6.5 x 5.7 x 4 cm
Watch Video

Unlike most specimens from this unique find the „bow tie“ habit epidote aggregates of this specimen are not loose but on matrix which adds much to the overall flavor here! The epidote has some contacts at the back but is all complete and flawless on the front where it displays its unusual shape with best sparkling luster! The matrix around the base is a combination of white calcite and some silvery green byssolite. The specimen is a complete floater and in very good condition all around!

Large, sharp chisel-tip terminated azurite crystal are pseudomorph transformed into dark matte-grey, almost black tennantite. The specimen is pure elegance and in very best condition! The front is all coal-black, the backside has some greenish-white coating accentuating the crystals structure. While tennantite itself is well known from Tsumeb the pseudomorph is rare and hard to find from the now closed locale. An attractive specimen in very best shape!

A fine, colorful tourmaline specimen that carries the beauty of Afghanistans mineral richness. It has four color zones: pink to light orange at the base, a thin colorless zone, a bright apple green one and pink at the termination! Especially the green zone is exceptionally gemmy and clear! The surface is lustorus on all sides, the termination is very well cut with a total of nine lustous faces! There is no damage all around. What looks like a repair at the upper third is nothing but an internal crack. Very bright and of great color and gemmyness as you can also see in the video!

LF308 - Tanzanite - Sold
Umba Valley, Tanga Region, Tanzania
Size: 5.3 x 3.9 x 2 cm
Watch Video

Tanzanite on Matrix is not exactly common so I was happy to lay hands on this fine little beauty. While it is not the biggest crystal the balance of crystal to matrix is quite ideal and the quality is great, especially towards the termination. While the lower half of the crystal has internal cracks and inclusions (the luster though is perfect even here), the top part shows best gemmy crystal quality. It’s transparent, vibrant and with a superb complex termination. You can easily see the color change too, blue with light from the back, purple with the light from the side. An amazing specimen for the size and beautiful too!

NI1 - Morganite - Sold
Dara-i-Pech pegmatite field, Chapa Dara District, Kunar, Afghanistan
Size: 6.8 x 6 x 4.8 cm
Watch Video

Somehow this is both, an aquamarine as well as a morganite, which is a totally amazing sight in person! The outer hull is a straight morganite yet from the inner core you see a distinct water-blue shimmer! The elongated morganite sits on a flat piece of feldspar that makes for a great background. Its surface is all lustrous, granting insight into the formidable, rather clear crystal. A view from the side or the bottom reveals the unique detail about the uncommon color: while the front half is straight pink, the backside is an intensive blue. Amazing!
