I wonder if the first one is even natural.goldierocks said:Doubt those IDs but it is impossible to give useful answers to people unless they do some of the hard work first (photos are always inadequate, you also need streak, hardness, SG etc). Do a search on "Series on identifying minerals" under my name.goldierocks said:MegsyB007 said:Hi XIV,
I'm no expert, but I'll have a go at some of these for you to look them up.
The first one looks like malachite (or an unusual black opal with only a green flash), the second one looks like opal potch, don't know the third one (opalised wood maybe?), and the fourth one looks like Amazonite.
Perhaps the experts can confirm or give alternatives?
Cheers,
