Everybody knows the eastafrican polycrystalline  Hessonites with their glowing orange colour. This glowing is caused by numerously tiny crystals which were grown with no orientation. The same composition (Grossularite instead Grossulare!) happened here with this fine stuff from the Umba-Valley but without colour.
4.08 cts., 10.7 x 7.0 mm

Leuco-Grossularite from Umba-Valley, 4.08 cts.  

Tanzanian Rhodolite
The 3rd hemisperical design from last week!

But the result says clearly it was worth doing so!

Val Val Smoky Quartz
This is a new hemispherical design faceted on a perfect piece of Smoky Quartz from Val Val in Switzerland. A total of 99 facets stands for lots of sparkles to all directions.

Vatomandry Sapphire
Very unusual Sapphire from the Vatomandry region at the eastcoast of Madagascar. Any inclusions? Yes, some Rutile needles and sagenittic Ghost Rutiles. Small enough to be invisible to the naked eye, but visible under magnification to show its natural and untreated state. The colour is a mixture from green, blue & grey in daylight while incandescent light turns the colour more to greyish. A very special gem for the collector and maybe a challenge for the jeweller.
2.02 cts., 7.9  x 6.4 x 5.7 mm

Vatomandry Sapphire, 2.02 cts.  

Savannah Tanzanite

Bleu de Auvergne-Sapphire
One of the super rare Sapphires from Massif Central region in the french Auvergne. Saturated greenish-blue (bleu-de-Auvergne) colour with highest possible clarity: a magnification of 45x won´t show the tiniest internals. Found it little creeks in this remote area of thousand volcanoes and extraordinaire cheese and sausages. What you see is the c-axis colour while the b- & c-axis colours are more greenish. BTW absolutely untreated in any way, no need for doing so after it´s such a beauty!!!

Pink Pastel-Pyrope
A new kind of trillion faceted in a Pastel-Pyrope from Ampanihy in Madagascar. These Pink Garnets are usually small, have a light colour combined with a high saturation and so can show all its sparkling power. I purchased a little parcel from a wellknown dealer at the Munich Show last weekend (oct, 25-28th) and this is the first I have faceted from the new lot. Good clarity with a few Rutile-needles and a hovering Pyrite crystal-cluster at half past seven.

7 Rutil-Quartzes
The  2018 theme for my collectors showcase are
"The Pleiades" a series of seven Rutil Quartzes made from a big sphere with frosted and glossy polished facets.
These gems looks a bit extra-terrestrial and share the same pavilion with different crowns. Due to the spherical frosted crown most crown facets are rounds or pitch circles. The third time I did this time consuming series.
Big pieces with weights from 24 to 42 cts.

Pink Ampanihy Garnet, 0.66 cts.  

Dinnehotso Chrome-Pyrope
This is a very big example of Arizona´s Chrome-Pyropes. Usually these are soo tiny that it doesn´t makes sense to facet them. Here is a bigger one closed to one carat. The colour is a very saturated and pure dark red. Under the binocular it shows its characteristic internal life with oriented rutile needles and some structure-relicts from another mineral that was also turned into Pyrope, very fascinating!
