I honestly have no clue what type of rock this is! I tried the picks in different areas, with different angles and pressure, and my results were all over the place. I wasn’t able to CONSISTENTLY scratch it until the 9 pick, although I started scratching more often than not with 7 (barely). Acid test was negative. Too hard for my streak plate. Don’t have a specific gravity setup but it’s surprisingly light for its size. Appears to have lots of little pockets of agate? At 20x magnification it doesn’t appear clastic, looks more like a swirly soup! Mystery rock used CONFUSION cabby is confused! cabby used DETECT but it failed! cabby is confused! cabby hurt herself in her confusion! ![](https://res.cloudinary.com/forum-rocktumblinghobby-com/image/upload/v1721584366/fmhogmsorpn6wlq0idrj.jpg) ![](https://res.cloudinary.com/forum-rocktumblinghobby-com/image/upload/v1721584364/t8pd341drmndrmfbds4k.jpg)

All I can tell you is that I haven’t seen any rocks or supplies post early 80s, and he was a huge fan of mail ordering from magazines lol
