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
Tanzanian Zircon, 2.01 cts.  

Vatomandry Sapphire
Greyish blue Sapphire from Vatomandry in Madagascar. Lots of tiny little inclusion makes it look a bit silky
0.77 cts.
, 5.5 x 4.0 mm
Vatomandry Sapphire, 0.77 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!
4.61 cts., 12.2 x 9.9 x 6.3 mm

Ejeda Spessartin, 4.61 cts.  

Blue Topas
Very brillant sky-blue Topaz (treated) with an additional row of facet in the pavilion.
2.06 cts.
, 7.4 x 5.5 mm

Blue Topas, 2.06 cts.  

Tanzanian Rhodolite
Pure red and very big Rhodolite in my "Opposed Bar" version. Flawless and absolutely no colour change. Bought the rough this year at the Munich Show and was happy to find a rough Garnet with the perfect shape for this design.
8.91 cts., 17.1 x 6.7 x 7.5 mm

Tanzanian Rhodolite, 8.91 cts.  

Queensland Sapphire
Little eyeclean greenish-blue Sapphire from Queensland, Australia, untreated.
0.34 cts.
, 3.7 x 3.7 x 2.8 mm

An "11Phase" cut Marolambo Garnet with some internals and nice colour.
1.66 cts.
, 7,8 x 4.4 mm

Marolambo Rhodolite, 1.66 cts.  

Madagascan Hessonite
Intense orange glowing Hessonite from Madagascar. The pavilion is a portuguese-type and reflects the light very well. In combination with a SRB-crown this is a modern and classical gem at the same time.Due to its multi-crystal structure it is silky and has some internals.
2.82 cts.
, 8.4 x 5.9 mm

Madagascan Hessonite, 2.82 cts.  

Ampanihy Rhodolite
The originally "Pipistrelli" in a darker Ampanihy RHodolite. I love this easy & fast cut, it helps me to turn small roughs and nice gems.
0.75 cts.
, 6.3 x 3.9 mm
Ampanihy Rhodolite, 0.75 cts.  

Madagascan Girasol-Quartz
Pipistrelli Girasol-Quartz from Madagascar, clean (with some silk) and brilliant.
6.73 cts., 13.6 x 9.9 mm

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

Mahenge Garnet, 3.09 cts.
Mahenge Garnet, 3.09 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.
0.47 cts.
, 4.6 x 3.1 mm

Tunduru Garnet, 0.47 cts.  

Antsirabe Tourmaline
Just a hand ful of unusual coloured Tourmalines have been found in a pegmatite near Antsirabe in Madagascar. Most have earthy colours in incandescent light but turn to much more vivid in daylight. This is salmon to copper and was cut into the classical "French Cut". Some little internals but nothing to see with unaided eyes..
0.62 cts.
, 4.9 x 4.9 x 3.6 mm

Antsirabe Tourmaline, 0.62 cts.  

Marolambo Rhodolite
Very saturated and dark (but not too dark!) Rhodolite from Marolambo in Madagascar. There are some internals visible - also for the naked eye -  but not too prominent.
Still a big sparkler!
cts., 11.2 x 8.0 mm

Marolambo Rhodolite, 5.54 cts.  

Utah Apache Tear
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.
0.97 cts.
, 6.6 x 4.9 mm

Utah Apache Tear, 0.97 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.
, 5.2 x 5.2 x 3.8 mm

Madagascan Rhodolite, 0.67 cts.  

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.  

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.
No colour-shift.
cts., 17.3 x 13.2 mm

Malawi Rhodolite, 25.60 cts.
