The entire mining area had a spiral structure. Looking down from above made one's hands and feet feel weak. It was said that flying over the mine was prohibited because of the intense convection caused by temperature differences, which could suck things in the sky into the mine hundreds of meters deep.
The work of mining diamonds was indeed quite complicated, but the Marquis family's people were willing to spend money. Moreover, this museum was open to the public for a fee, making the mine a famous tourist attraction with many visitors every day.
Upon entering the interior of the mine through an elevator, it was revealed that the museum was carved out from the mountainside. Its designer was a master architect from Europe.
This Diamond Museum had four levels, classified according to different qualities. Of course, quality was not limited to the diamond's grade; excellent cutting craftsmanship could also significantly enhance a diamond's value.
