No, diamond is the hardest naturally occurring mineral.
Jade has more density than a diamond. While a nice size jade block "may" fracture a diamond; the diamond "will always" scratch the jade stone. Many people confuse the diamond with being a strong stone. It is not! In fact the diamond is easily fractured. The diamond is however very hard (not strong but very hard) Diamonds can scratch just about every surface on earth.
The only thing stronger than diamond is laser, only laser and diamond can cut itself.
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).
