Tanzanian Zircon
 
Golden brownish Zircon from Tanzania. In my eyes Zircons are too often overseen as they are such a sparkling and brillant gem material. Easy to cut and always takes a fine & fast polish and easily to detect due to its strong birefringence.
2.01 cts.
, 6.5 x 5.3 mm
available
 
Tanzanian Zircon, 2.01 cts.  



















 
 
Surselva Smoky Quartz
 

The nicest Smoky Quartzes comes from (in my opinion) the Surselva region in Switzerland. They often have a warm and charming brown colour instead of the often seen greyish ones. This is faceted as a "Floret" even it is not a small gem I decided for the floret-pattern and it is shown so well, Completely clean
4.52 cts., 10.9 x 8.6 mm
available

 
Surselva Smoky Quartz, 4.52 cts.  



















 
 
Ampanihy Pink Silk Garnet
 

The biggest of the "Ampanihy Pink Silk"-Garnets I have cut so far. Great colour as always but with visible internal and some on the surface.For those who can handle the small inclusions it is still a nice gem.

available

 
Amethyst, 1.32 cts.  



















 
 
Madagascan Demantoid
 
One of the very few Demantoids with IF-clarity, this time from Madagascar. The colour is a fine minty green and has to be named strong for non-metamorphic Demantoid (unlike the dark green one from Russia and Kerman). The dispersion in sunlight is just superb!
0.37 cts.
, 4.4 x 2.9 mm
available
 
Madagascan Demantoid, 0.37 cts.  



















 
 
Erongo Demantoid
 
This one was a hard fight. The rough was a big piece with 2.5 gram and only one half had a better clarity. The result still has many internals, but hey this is a Demantoid with over one carat! WIsh I would have more roughs even with this inclusions. The "Lighthouse of Porporela" with extra steep angles gave an extra portion of colour and dispersive flashes.
1.22 cts.

available

 
Erongo Demantoid, 1.22 cts.  



















 
 
Bolivian Ametrine
 

The bolivian Ametrines are harder to find on fairs like SMAM or the Munich Show and I have my stock close to exhausted. Hope that this year in the Vosges Mountains (SMAM) I will find some new ones.
Here I have a bigger one that was faceted into Marco Voltolini's Cushion cut but received an extra row of facets on the crown. There is just thing I have to say against this one: There is a trouble zone of an imperfectly healed crack at around 4 o`clock. Please click on the pic to see it better.
13.91 cts., 15.4 x 12.8 x 12.1 mm
available

 
Bolivian Ametrine, 13.91 cts.

Russian Citrine, 11.19 cts.  



















 
 
Madagascan Teal Sapphire
 
Another fine example of t he new Sapphires from the gem-isand Madagascar. Found - as most Sapphire & Rubies from Mada - in the steep mountains of the east coast. Here you can see some very decent internals, even enough not to detract its brilliance and sparkles but enough to prove its natural origin and being free from any treatment.
Anyway irl this big beauty has a much more vivid teal colour compared with this poor pic!
2.43 cts.

Tunduru Garnet
 
Ten years ago I purchased a parcel of small rough from Tunduru from a married couple who travelled around the world and collected rough gems in creeks and quarries. This is a nice addition for Garnet collectors. Some fine silk only, otherwise clean.

, 4.6 x 3.1 mm
available
 
Tunduru Garnet, 0.47 cts.  



















 
 
Madagascan Rhodolite
 
The original "Glacial Ice" design in a dark-red madagascan Rhodolite. The name of this design comes from a trekking tour in the alps when I was so impressed by the many glaciers and its icy-blue colours in the early summer. I first cut it into an alpine Smok Quartz. But this one shows more of a equatorial heat. Anyway a bit unusual mandrel-shape.
0.67 cts.

Tocantin Almandite
 
The Almandites from Tocantin in Brazil occur in big crystals in sizes up to a golf ball. Some hundred meters under the earth surface is a metamorphic layer with superficial strong eroded crystals. Only small parts are usable for faceting due to inclusions and dark colour. But there is a nice magenta hue

Rescued Tourmaline
 
From a parcel of native cut Tourmalines this one caught my eyes at first and screamed "I wanna become something much better". Done, the result is the "Flandriant" design a squarish brilliant with lots of life. It loves natural daylight while incandescent or LED light adds some brownish modifiers.
1.77 cts.
, 7.1 x 5.5 mm
available

 
Rescued Tourmaline, 1.77 cts.  



















 
 
Achroite
 
Is this Achroite or just a very light yellow? Hard to say. What I surely can say is this gem is brilliant and has good clarity just some internals at half past five and faceted in my "5er Brillant" design.
1.26 cts.
, 6.9 x 4.9 mm
available

 
Achroite, 1.26 cts.

available

 
Pink Tourmaline, 0.98 cts.  



















 
 
Ejeda Spessartine
 
My madagascar-dealer surprised me this summer with a lot of Spessartines from Ejeda. I didn´t knew that Madagascar also has orange coloured Spessartines. Maybe not the same type of colour as Mandarin-Garnets used to have but the internals with some horsetail like inclusions reminds me on the very few ones from Namibia. Cool stuff with very unusual colour, a fine addition for garnet lovers!

available

Madagascan Rose Quartz
 
This big triilion shaped gem is a top Rose Quartz from Madagascar. Had to worked around some superficial troubles at the rough stone to get the best out of it and it is still a big gem. Only a small amount of silk shimmers through the soft pinkish colour.
7.81 cts.
, 13.0 x 10.2 mm
available

 
Madagascan Rose Quartz, 7.81 cts.  



















 
 
Madagascan Chalcedony
 
This years Munich Show was in the dimension of the pre covid years with over thousand dealers from all over the world. I was focused on Chalcedonies in different colours after I'm  very familiar with this gem (details will result in a special newsletter sometime when I have emough different stuff). This one is from Madagascar the a very decent hue and shows the soft and slightx glowing  that is zypical for lighter Chalcedonies. I just love them even the daceting is time consuming due to the unexpectable hardness of the micro Quartzes.
2.88 cts.
, 9.3 x 6.8 mm
available

 
Madagascan Chalcedony, 2.88 cts.  



















 
 
Light Surselva Smoky Quartz

Madagascan Hessonite

available

 
Madagascan Hessonite, 2.82 cts.

available

 
Madagascan Girasol-Quartz, 6.73 cts.  



















 
 
Mahenge Garnet

 
Extremely saturated magenta pink Mahenge Garnet. Really hard to catch fine roughs in this size. And no question these rare Garnets are expensive even if it has some internals like this one. But hey the colour is unbelievable and shifts a bit from magenta red in incandescent to more pinkish in fluoro light.
3.09 cts., 8.6 x 6.3 mm
available

cts., 11.2 x 8.0 mm
available



 
Marolambo Rhodolite, 5.54 cts.

Volcanic glas from Utah. A bit tricky to cut and polish due internal tensions but always worth faceting this special type of gem. Some hard to find internals surrounded by a fine and soft brownish colour.

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.
available




 
Pink Ampanihy Garnet, 0.66 cts.  



















 
 
Malawi Rhodolite

 
The biggest sevensided Tudor´s Kaleidoskop I have ever faceted (there is also the sixsided version). It is so hard to find a dealer with these big beauties in good quality with such perfect clarity and even not to dark.
