JY192 - Tourmaline - 3100€
Alto Ligonha Pegmatite Field, Zambezia Province, Mozambique
Size: 6.2 x 2.3 x 2.1 cm

This single crystals tourmaline from Mozambique features open and beautiful colors! Even low backlight illumination reveals an interplay of strong golden yellow and candy pink that runs like a pillar through the center and caps the crystal at the top. For a nice look on that pillar please regard the third picture above.
The first picture shows the piece with both backlight and incident light. The second one has no backlight at all which is still nice but of course lacks the radiance. The tourmaline is in very good condition. It is doubly terminated and has only some small chips that aren’t visible from the front.

A 2.3 cm spessartine aggregate is set on a lovely combination of white feldspar, silvery muscovite and two smaller spessartine crystals. The garnets are rather dark but show bright red patches along the surface if you add some direct downlight. They are very well crystallized and in near-flawless condition. Very attractive in person!

In 2013 the famous Watercourse Pocket was opened and held some of the best specimens ever to be found in the Milpillas mine. This rich and spectacular floater specimen was part of that find. The crystals are sharp, highly lustrous and of the brilliant electric blue color everyone is in love with. In between the rhombic azurites you can see pseudomorph malachite after azurite. Most of that malachite however has been overgrown with a second generation of azurite which then creates that bright and easy to illuminate blue color. Absolutely breathtaking in person and all over in fantastic condition!

Color, luster and clarity of this zoisite are absolutley brilliant. The color of the upper half of the crystal is an intense greenish yellow when lit from the back and somewhat paler when you look at it through the sides. The lower half is opaque and dark, thus almost creating the impression of a matrix-piece. The whole crystal is perfect with a pristine termination and no damage to be found anywhere. The bottom also is recrystallized. At the left side you can see a broken and rehealed side crystal, influencing the growth of the zoisite. Mirroring luster and appealing color are distinguishing this wonderful piece!

This exceptionally fine spinel specimen found at Pyan Pyit in the famous gem district Mogok!
It presents a single spinel crystal atop a contrasting white calcite matrix. The spinel is up to 2.1 cm on edge and displays intensive pink to red color. At closer inspection you see the translucent crystal being shot through with gemmy patches which makes it very easily lit! On the lustrous surface you can see subtle etchings which has a lovely visual effect without disturbing the well developed octahedral crystal shape!
The classic aesthetics of one single crystal on matrix very much highlights the spinel as the rare and beautiful gem it turly is! As you can see in our video, the spinel is complete all around and there is no damage whatsoever! An exceptional specimen of this rare gem mineral!
