OK, Tom's cabochon post started me on a quest to understand vogesite. When searching that it referred me to Pyrope, and I understand there is a connection in that both materials have garnet inclusions, seemingly the garnet is not just as well formed as crystal, vogesite being a less refined version of pyrope with the pink spotted sort of melted garnet inclusions. Do I have this right? The range of photo images is so wide that I am confused in trying to sort it out. I'd love to see photos of rough and polished pyrope/vogesite and hear about it. I know you all are a great resource, the combined brain power of this forum is formidable. help me understand? thanks in advance!

Maybe there is some confusion on the name vogesite. The material I have is not crystalline at all and does not appear to contain crystals or garnet. It appears to be a microcrystallne quartz cabbing material very much like a colorful chert or agate from South Africa. Sellers call it jasper but it is highly translucent in sections and looks closer to agate to me. Really awesome stuff that sometimes has great dendrites and pictures......Mel

Thanks Mel, still trying to sort it out. Braders, you sent garnets, if you sent pyrope I was too ignorant to see it and will have to go back out to look for it (but not today, that garage is 24 below at the moment). No doubt there is some there, I just didn't recognize it as such. Still learning! Thanks! hopefully more folks will chime in with explanations and illustrations. I'll spend more time on the internet as well and eventually the light will dawn.

ahhh substitute by google for what it "thinks" I mean. And I am dyslexic enough I did not find it. vosegite indeed. Thanks shotgunner for pointing that one out! (sometimes I hate google.)
putting the link back, it is the correct information, just the wrong spelling on the website. starting to make more sense now. eventually it will all make more sense.

Here are a couple of pics of the jasper trade named Vogesite. Think the name is after a river or region in South Africa or some such....Mel slab of common type: Big fancy boulder I have in the rock pile. Lots of dendrites and scenes in this one.

Chunk looks like Rockyraccoonzite, Mel. : )

Mel, that looks like most of what I am seeing when I do internet searches, and they call it vogesite jasper. So is that both vogesite and jasper, or like some other "jasper" types and not jasper at all? Really colorful stuff that looks like it will polish great!

Parfive: That it is. I got a load of rough from Kim. She is a real sweetheart.
snowmom, the jasper does polish great. Pretty hard stuff,more like agate actually. There is apparently a mineral or rock type called vogesite too and that is the material with the included garnet. I don't know anything about it and it's not in my mineral books either

Vosegite or Vogesite ?? Spelling is important. Write? Right?

ordinarily mindat.org is a pretty good and reliable site. Did they mis spell it, or did I search for the wrong thing?
OK I found what you were referring to, thanks for pointing it out. Link deleted, comment on google substitution- suggestions added.

Snowmom your determination in understanding geology more specifically petrology is admirable. Maybe I can clear something up on this pyrop/vogesite issue. I had to look this up to jog my memory.Pyrop is a mineral species of garnet, whereas vogesite is an assemblage or mafic(dark) minerals like biotite mica and hornblend minerals that occure as euhedral crystals called phenocryists formed in a fine grained groundmass (matrix. Vogesite is most commonly associated with Lamprophyric dykes and sills. Is this clear as mud? try this wiki link en.wikipedia.org/wiki/Lamprophyre#Vogesite

turns out it was the website, the information is the same as minerken shared, but the spelling of vogesite is not correct.(spelled vosegite on that site) No wonder I have been confused. hooboy! www.alexstrekeisen.it/english/vulc/vosegite.php

Hello all, I know this thread is a bit old, but if you are still interested in Vogesite? For starters, just for info... the source location is Voge Farm, Prieska, Northern Cape Province, South Africa. It is not the same as that mineral "vosegite". It is named after the family farm where it is found.:-) Also if anyone is interested in rough, I still have a bit over a ton available. I imported it over 10 years ago, then moved out of the country for my husband's work! So its still sitting in Virginia! :-) www.gemstone-elements.com for pictures of the crates. Oh & I have started slabbing some of it and am currently offering it slabbed on ebay as gemstone-elements Happy cabbing!
