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

  • $\begingroup$ 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.
