Why can you see through H2O as both a liquid and a solid but you cannot see through something like Au (gold) in a solid state? Is this a matter of density?

Imagine light as a beach volleyball. You can have a densely packed field of amateurs which not a single one capable of blocking the ball. Likewise a single pro may easily stop it.
It’s all about proficiency.
Similarly, light can be blocked by interacting with electrons of atoms. But depending on some factors, those electrons can only absorb light with a specific energy. In gold and other materials, this energy falls in the range of visible light. In case of water it falls in the range of infrared while visible light is not blocked.
