Raysun Posted June 5, 2023 Share Posted June 5, 2023 I have photos to share and was hoping someone could help to identify them for me, thank you. Link to comment Share on other sites More sharing options...
Danielb Posted June 5, 2023 Share Posted June 5, 2023 Where did you find it? I’m not too good with crystals but maybe a copper crystal like azurite. Link to comment Share on other sites More sharing options...

I inherited a collection from a professor of geology and now just going through them so unfortunately I don't know their origins other than he was originally from Indiana but lived in Silver City NM .

grandpa Posted June 5, 2023 Share Posted June 5, 2023 These appear to be copper minerals. I think I see azurite and chrysocola plus others. Link to comment Share on other sites More sharing options...

I have other rocks that I thought were Azurite and they are different in color and texture. Are there variations in the host matrix or color?

grandpa Posted June 5, 2023 Share Posted June 5, 2023 Azurite is characterized by the deep navy blue shown in the sample above. There are other blue, aqua, blue-green, green-blue, green, deep green . . . copper minerals that are found in association with azurite. Some of these include linarite, brochantite, malachite, rosasite, chrysocolla, turquoise, to name a few. Various tests for hardness, streak color, specific gravity, luster, crystal morphology etc. are used to help distinguish the IDs. Link to comment Share on other sites More sharing options...
