  • $\begingroup$ looks like amber to me en.wikipedia.org/wiki/Amber What density is it? If it is low density (slightly more than water) then amber, otherwise not. $\endgroup$ – DavePhD Jun 13 '16 at 16:51
  • $\begingroup$ Looks like a glass fragment on first guess. It's not a mineral from first glance no crystalline structure (amorphous). $\endgroup$ – Michael Wallace Jun 14 '16 at 2:02
  • $\begingroup$ Either citrine (a type of quartz) or glass. I'm guessing it's more likely to be glass. $\endgroup$ – Gimelist Jun 14 '16 at 4:57

If it has a low specific gravity, of about 1.1 , burns and carbonizes in a hot flame then it is amber. If it has a specific gravity of about 2.7, and scratches glass easily, then it is some variety of silica, such as quartz or agate. If it barely scratches glass, and has a specific gravity of between 2.4 and 2.7 then it is most likely just brown bottle glass.

  • $\begingroup$ It is pretty heavy. In water it sinks to the bottom. I heat it up as much as I could. It did not break it only showed few cracks in the inner part, it did cool down very fast in water. I found it in the mountains in the area where rain is pouring down the mountain. I was able to scratch glass and steel easily. $\endgroup$ – Midhet Jun 14 '16 at 17:48
  • $\begingroup$ Then it is probably some kind of silica. What is the geology of the mountains where you found it? $\endgroup$ – Gordon Stanger Jun 15 '16 at 4:41
  • $\begingroup$ From my research, it may be a Fold mountain. I have uploaded a few pictures to imgur, maybe they can help. imgur.com/a/kylVf $\endgroup$ – Midhet Jun 28 '16 at 7:15
