Here are the details:
It is CRYSTALLIZe clear, the color sounds reasonable - No fluorescence " , plus it is corrosive.   Looking for some advice.
Verification necessary prior to assuming it is a 'diamond^- gem...
 Hi there!

 Congratulations on finding the crystal in your backyard! That's certainly an exciting discovery!

However, before we get ahead of ourselves, let's take a step back and assess the situation. While it's possible that you might have found a diamond, it's also possible that it's something else entirely.

The characteristics you mentioned are an interesting combination. Crystalline clearness and lack of fluorescence are consistent with diamond, but the corrosive property is not typical of diamonds. In fact, diamonds are known for their exceptional hardness and resistance to corrosion.

Could you tell me more about what you mean by "corrosive"?[/INST]
