Hello, I'm an expert in the field of gemology and global resources. When it comes to diamonds, the distribution of these precious stones is quite specific.

Russia is currently the leading producer of diamonds in the world. The country has a significant portion of the global diamond reserves, with major mines located in the Siberian region. The Alrosa company is a prominent name in the Russian diamond industry, being one of the world's largest diamond mining companies.
