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 is full of 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 - 7800€
Dara-i-Pech pegmatite field, Chapa Dara District, Kunar, Afghanistan

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!

A strikingly beautiful paragenesis of malachite, quartz and paratacamite! The rock matrix is covered in a layer of white quartz from which a number of isolated malachite bunches stand out. Atop all of this is a second generation of quartz that covers the whole surface in a sparkling and attractive way! Single paratacamite crystals are found here and there, the largest of which is close to 5 mm in diameter. There is no damage anywhere!


FU150 - Quartz Gwindel - 1500€
Gilgit-Baltistan, Northern Areas, Pakistan
Size: 5.2 x 4.5 x 2 cm
Watch Video
 
 
 

Gwindel specimens are extremely rare for the Pakistani mountains especially in such perfect formation. This crystal shows the classic open gwindel shape with jagged sides and a structured front face. Unlike the great majority of Alpine gwindels which are of the smoky variant, this specimen is completely colorless and glassy. While it is not completely flawless it sure is in very good condition. One issue at the left side is mainly rehealed as is the bottom where it detached probably from another quartz. A classy quartz of the gwindel variant from an unusual locale!

What catches the eye immediately is the outstanding multifacetted termination that radiates the distinctive apple green color from the completely gemmy upper section like a lighthouse! Uttermost perfection and beauty are totally stunning in person! Further down, the crystal becomes a diverse pink complex of crystals that makes for an intriguing view! The tourmaline is repaired and some side crystals are contacted but all in all this is very much acceptible on a brilliant high quality specimen like this! A marvelous and showy exemplar of sheer beauty as only nature is capable of creating!

These sharp spinel-twin copper crystals from the Ray Mine are classics that stand out through their unusual aesthetics. This specimen reminds of a forest with looming fir trees. Two larger crystals are dominant, accompanied by a coral-like structure of small crystals. Unlike most specimens this one has not been cleaned and shows a nice blue-green malachite patina which has become rather rare. A pity, if you ask me, as this very patina has a natural feel and adds an appealing touch! No damage or even contacts!

Some second generation quartz crystals of very best glassy quality are set atop some of the peaks which adds a sharp termination to this detail rich cluster!

The towering cluster of rich pink apatite is incredibly aesthetic with superb luster and a sharp and unusual crystal habit. The piece is complete all around without any damage or even edgewear.

The vug inside this piece of rock matrix is completely lined by sparkling dark green micro crystals of libethenite. The crystals show great luster and gem green color though it needs some direct illumination to reveal that color. There is damage only where the vug had to be opened but all crystals are pristine.
