Sketch Posted September 19, 2021 Share Posted September 19, 2021 (edited) I got this sapphire from bulk of soil which was brought from a mountain. I scratched it with glass and it was genuinely hard. 20210919_205118.mp4 Edited September 19, 2021 by Sketch Quote Link to comment Share on other sites More sharing options...

Quartz is much harder than glass. Quartz will scratch glass very easily. Glass is 5.5 and quartz is 7. Find (another) piece of quartz and scratch it. If that does not work rub it on your toilet tank lid Quote Link to comment Share on other sites More sharing options...
Sketch Posted September 20, 2021 Author Share Posted September 20, 2021 Ok I think rather then ruby it is a sodalite. Quote Link to comment Share on other sites More sharing options...

A solidite? Is that like a carbanodo? You mean sodalite? I honestly don't know what it is. It looks granular to me. But I have no idea what it could be. Let's just call it a ruby.

Now I don't know if it is powder of quartz or quartz has scratched it successfully. Edited September 20, 2021 by Sketch Quote Link to comment Share on other sites More sharing options...
4meter Posted September 20, 2021 Share Posted September 20, 2021 Hello Sketch, Your 4'th and 5'th pics look like corundum (same mineral as Sapphire, just not blue color) a non-precious aluminum oxide mineral. Your last photo seems to shows Quart powder on the sample. Try the test again, and see if the Quartz "bits" into or gouges the test sample. If it does, the sample is harder than Quart. I would say that you have samples of Corundum. Quote Link to comment Share on other sites More sharing options...

I would say that you have samples of Corundum. The quartz bits has easily scooped off from its surface so I think it is harder than quartz. Just like a gemstone should do.

Sketch Posted September 21, 2021 Author Share Posted September 21, 2021 I think my previous photos were not of good quality. I am posting some good photos so they will be good for examining. Quote Link to comment Share on other sites More sharing options...
Sketch Posted September 21, 2021 Author Share Posted September 21, 2021 (edited) If you will see my above photos it contains so many black inclusions which is actually a good sign which Indicates that it is a sapphire.this is an Sri Lankan blue sapphire which has exactly same inclusions. But the problem is that my specimen contains so many black inclusions that it makes it poor quality.

4meter Posted September 21, 2021 Share Posted September 21, 2021 I made a typo in my last post. It should read thus "Try the test again, and see if the Quartz "bits" into or gouges the test sample. If it does NOT," Sorry for any confusion. Quote Link to comment Share on other sites More sharing options...
4meter Posted September 21, 2021 Share Posted September 21, 2021 Ruby and Sapphire are the deep red, and deep blue colored varieties of corundum. Just in case anyone wanted to know. 1 Quote Link to comment Share on other sites More sharing options...

Just in case anyone wanted to know. Actually, to gemologists, all corundum other than red is sapphire, regardless of color. Blue is just the most common.
