Rust, which is the most common form of corrosion, would make it weigh more. This is because rust is metal combined with oxygen, which means that you've added something to the metal. Logic tells us that mass + mass = more mass. Iron/steel + oxygen = mass of iron/steel+oxygen.

Additional weight is also added with the actual quartz.

So no, the sword did not reduce in weight due to the quartz. And even if it did lower the weight, it wouldn't matter. Because putting a stone that dissolves metal on a metal weapon still makes absolutely no sense. Thus Dark Souls logic still applies to this weapon.
