The site where it is found is characterized by schist, quartz and gneis, but also other species of rock. This is a scissors 2 cm semi transparent, vitreous luster, hard scale 6.5 - 7 ... I will post more photos of different kinds found in the location where it is found possibly serving as identification help ... thank you

enter image description here1...?

enter image description here2. ...?

  • $\begingroup$ Given the scale these are "pebbles", not "boulders". Some of these are round. Did you find them in a riverbed? $\endgroup$ – Spencer Jun 9 '18 at 23:30
  • $\begingroup$ Yes, thank you ... they are all found on the river bed, there are also rocky mountains nearby ... I'm a beginner and I'm collecting except for "pebbles" but the rock is very specific to my experience correctly authenticated type ... thank you $\endgroup$ – Ymer Zumeri Jun 10 '18 at 7:45
  • $\begingroup$ Thank you, Mr. Spenser, I would like to ask you for further consultations on stone identification ... thank you very much ... $\endgroup$ – Ymer Zumeri Jun 12 '18 at 0:44
  • $\begingroup$ The third one looks like it might be limonite. $\endgroup$ – dtech Jun 12 '18 at 13:46
  • I have no idea what image 1 is, but the dark red/purple crystals look like they could be garnets.
  • Images 2 and 7 are both schists 2 is of a lower metamorphic grade than 7 which might even be considered a gneiss.
  • Image 3 looks like calcite veining in a fine sandstone parent rock.
  • Image 4 looks like flint, chert or chalcedony, but may well be talc, or calcite depending on it's hardness and reactivity, there's not a lot to tell between them visually a lot of the time.
  • Image 5 looks to be beach worn bottle glass, I have pieces that colour at home.
  • The pebbles in Image 6 include what appears to be obsidian, jasper, travertine or possibly coral, calcite, argillite, and sandstone or possibly quartzite.
