Gold can be both soft and hard depending on how pure it is, pure gold (24K) is softer than a gold alloy. And the lower the number the harder it is. 10K is harder than 14K, 14K is harder than 18K, and 18K is harder than 24K (pure gold).
10kt jewelry is not worth as much as 14 kt gold. But the worth is determined also by the amount of grams.
No.
emerald
Yes - 22ct is a much higher purity than 9ct gold.
No. Diamond is harder than emerald.

No, gold is not harder than pyrite. Pyrite has a hardness of 6-6.5 on the Mohs scale, while gold has a hardness of 2.5-3. This means that pyrite is harder than gold.
Silver is harder than gold but softer than copper.
I would say emerald. It's far rarer than gold.
No, pure gold is softer than a paperclip. Gold is a malleable metal, which means it can be easily molded and bent by applying pressure. A paperclip is made of steel, which is much harder than gold.
Yes an emerald or green beryl is harder than quartz
no

Because there is less of them than gold and they are harder to mine.
it is harder to get than gold and the process is longer
because natural emeralds are harder than a synthetic emareld
