Gem Posted September 20, 2021 Author Share Posted September 20, 2021 I think this is what an exact raw sapphire looks like. Link to comment Share on other sites More sharing options...
Jim in Idaho Posted September 20, 2021 Share Posted September 20, 2021 If it is, it's definitely not gem quality. What's it look like dry? Jim Link to comment Share on other sites More sharing options...

kac Posted September 20, 2021 Share Posted September 20, 2021 Looks like quarts but i'm no expert. Just seen similar stones in my area where we have a lot of quarts. 1 Link to comment Share on other sites More sharing options...

kac Posted September 21, 2021 Share Posted September 21, 2021 Your specimen. They could very well be sapphires but in particular the top left one doesn't look like the samples. I just see a lot of speckles in them so hard to really tell. Chris Ralph did a set of videos worth watching, very interesting. May help in finding out. 1 Link to comment Share on other sites More sharing options...

Jeff McClendon Posted September 21, 2021 Share Posted September 21, 2021 The dark gray with a slight blueish tint and the tiny black inclusions are very characteristic of some industrial grade corundum. I would not be able to say your original photographed specimen is a sapphire (even if it is corundum)due to its poor quality. What I don’t see is any remaining crystal faces or any very characteristic basal parting. Corundum variety Sapphire is so hard that there are usually some remnants of its crystal faces and parting in most specimens. Instead I see a water worn, conchoidal fractured specimen with no hint of worn flat sides, with cracks running in several directions that do not exhibit basal or rhombic parting. 6 Link to comment Share on other sites More sharing options...
