here is no better way to describe it... This hobby shows every mistake you make, and there is no way to hide it. I recently bought a wheel, but it was not love a first sight, so I joined this forum to learn and straight away manofglass spotted a newbie in need of some help so he sent me some great links from this forum and I read every single one several times, but this video made me decide to give the wheel a second chance forum.rocktumblinghobby.com/thread/40548/stonesthatrock-cabbing-video-tutorial It is still not love at first sight, but there is improvement - so I'm hopeful for the future Eyegneiss Porfyr (love the thoughts of this being brought to denmark by the ice from Norway and Sweden) Granite/kvarts ? Really nice grey granite I had to redo after drilling(Yes it's slightly off center - That's one of the joy's of being a newbie) Unsure if this is porfyr, it looks different from the ones I normally finds. Sorry for the crappy Iphone picture, it's really smooth and shiny in real live.

I really like that first one. I've never heard of eye granite before.

It does look more like gneiss than granite though. I just hadn't heard of either of them with "eye" in the name. Thanks for educating me.

Gneiss with eyes is called Augen Gneiss even in "English", tho Augen is German (/Germanic). I've got some from S.France lying around somewhere and never thought to cab it!
I'm not sure of the etymology of the word Porphyr, but it exists pretty much in the same state, again in the 'English' Geological language: porphyry is a crystalline rock where one of the mineral species outgrows the others: megacrysts c.f. microcrysts.
Those cabs are super and your material, whilst native to you, is really quite exotic.
Now where did I leave the augen gneiss... in the garden I think!

Since I'm an etymology freak I looked up porphyry (I'm sure porphyr is from the same root): "late Middle English: via medieval Latin from Greek porphuritēs, from porphura ‘purple.’" I don't think all porphyries are purple though.

I guess its similar to the botanical (latin) "purpurea". I wouldn't have guessed that so well done on researching that. I would agree, not all porphyrys are purple, but one of the principle porphyrys would be plagioclase feldspar (pink) in granite. Pink / Purple ... eeaahh, tenuous.

Sorry, still needs to learn their names and furthermore translate them, But just checked and it said Porphyry in English just like you said. No they don't just come in purple, they come in red, grey, black and yellow like the 2 in the top. And the last picture is also identified as an porphyry www.google.dk/search?q=Rombeporfyr&source=lnms&tbm=isch&sa=X&ved=0ahUKEwiMsNrDj4DNAhUCVSwKHazkBd0Q_AUIBygB&biw=1391&bih=683#imgrc=_They don't tumble that well due to the different materials. But I keep collecting them because of the variety, it's not a rock that originates in Denmark, but we got plenty of from Norway and Sweden.

Interesting stuff... The name porphyry was initially used to indicate a rock extracted in Egypt, known in ancient times as Imperial Red Porphyry or Ancient Red Porphyry. It was extracted in the Egyptian desert in the mountain Jebel Dhokan (up to 500 A.D.) and it was used to build columns, vases, sarcophagus, busts, etc. Reference@monna, again, it's the same in English, Rombe = Rhomb, being phenocrysts of rhombic shape. So while you've taken a liking to rombeporphyr, don't imagine it is in any way common - it only occurs at 3 known locations on the globe: continental rifts & you happen to be at / near one of them. Lucky you!

I love the stones! And, as far as I can tell, you're doing great cab work, too!

They're all beautiful, but I think I like the granite/kvartz one with the rough top the best. That is just a really cool way to finish that stone IMHO. It helps you to remember that stone in its rough state. Thank you for sharing!

You are doing great. Definitely better than my first cabs.

You are doing well. I think you are starting with difficult material. You'll really enjoy nice, solid, uniform material when you get some, my guess is most of what you are working is mixed hardness, with pockets in some cases.
