Slab measurements are approximate. When we measure a stone, we don't measure from it's extreme pointy little tips. We measure the usable body of the stone for lapidary purposes. When you receive your slab, it will be bigger than the description by 5-15mm.
Today, mines in northeast Afghanistan are still the major source of lapis lazuli. Important amounts are also produced from mines west of Lake Baikal in Russia, and in the Andes mountains in Chile. Smaller quantities are mined in Italy, Mongolia, the United States, and Canada.
