rock 1: 4.7oz. does not scratch glass or streak Moh 4? 3 " at longest point no luster when dry
Rock 1 of 2 back view: 1.9oz 2" at longest point does not scratch glass or streak color dark bluish gray.
Rock 2 of 2: color difference and inclusions?
Rock 3: 4.6oz 4" wide scratches with fingernail , translucent agate cabbing Slab? What type?
I was given a large collection of mostly lapidary stones (rough). There are some specimen pieces, but their identification is down the road. I have bought 5 books, borrowed at least another 3 from the library so I have identified some of the collection (maybe 85%). My particular problem is that the coloration, inclusions, shape of quite a few look the same! I am out of breath. I love the process of identification and when I do identify one accurately, I hop around like a fool. In essence, I have become intrigued with them. But I have come to a halt. Can anyone give me any pointers that may stop me from ripping my hair out?
I greatly appreciate any help you may give in advance.
