Hii rookie, looks like I'm not too far from you.. Lake/mchenry county myself. Wondering if the stones you found might be spinels/spinnel?..

Astrobleme is giving you good info. He has helped me a lot, as has the former Wyoming geologist D. Hausel. Since you soaked them already in Whink, the appearance of the stones suggest that they are not diamonds. They do appear to have been frosted by the hydroflouric acid, which only happens if Si is part of the chemical makeup. Other crystals do have octahedral habits, and could possibly be zircon. You need to scrutinize them under a microscope. A good one can be obtained from Amazon for less than $100.00 and include a monoscope camera attachment. You need power of at least 10x up to 60x to see the stone well. As to fracturing diamonds by hitting them, they can have conchoidal fracture...I have several that do...just like glass. Usually with a light tap, they will fracture along cleavage plane of crystal. But if it's glass, it will definately pit with Whink.

Not all Whink is created equal.

Only
the brown bottle Rust Stain Remover has Hydroflouric Acid. Their other products will not work. Whink Rust Stain Remover has a very weak Hydroflouric Acid solution (1-2%) so it may take a while to see any effect.
