Not an expert by far but looked like alot of is jasper. Im sorry that 2nd pic reminds me of petrified poop lol its not but I've actually seem some i didn't know i had it in my rock collection lol yellow rock is gorgeous. I hope someone with more knowledge comes along. I don't get much help either
I was gonna say agate seeing the inside but yes all in the quartz family. I have rock with crystal attached i broke a chunk off of and im clueless too lol other than prob some type of quartz. It grows weird i think lol did you have a clue? Lol
I don't metal detect often at all maybe i should but id need a bigger one im sure. That lil flower piece idk if that's costume jewelry or not but it looks like ethiopian opal. I do rocks gems minerals geology amateurist basically lol nice
Ty i have one just takes forever there's 3lbs going most the time lol that first pic looks like someone tried to tumble clear and milky quartz and gave up found walking bike trail that goes all over town. Others in creek beds. Thx again
That is how we generally test to know if its in the flint family. I know quartz is in most of what you mentored but I've never had a spark from Agate or quartz itself. Still learning been yrs and still learning lol still have many rocks i can't identify i believe they are in the quartz family...
