Brandywine creek pa finds
Alright so I am an entry level hobbyist. This is my first actual outing in a natural area(that isnt a dump pile)... I think I did good. All of these looked different in the creek. One of them was a deep blue(navy) and I can't seem to bring that color out. I have cleaned all of these with vinegar water, then borax water, then iron out because a lot of these had heavy iron. A few of these look like greyish blue but not colorful either. I feel like some of these are citrines, some agates, some milky quartz and others idk.
I scrubbed all of these intensely. took 2 days. After iron out I soaked in water, emptied, soaked in water again, emptied, soaked in water, emptied, finally borax + dish soap water.
All this got the algae off.
The one that was blue in the creek never turned blue again once it dried. Even when i soaked it in water before the cleaning. Any ideas?
