Traditionally, the end of Europe and the start of Asia is defined by
the Ural River running through Russia and Kazakhstan. This places around 75% of
Russian territory in Asia, yet only around 22% of Russia’s population lives in
this area. This means that despite being a predominantly Asian country by
territory, most of Russia lives in Europe.
Hi! Sorry to bother, but you know the density of an Esmerald? And where to find them? Sorry for the bad english.
Its density is 2.67-2.78 and It’s hardness is 7.5 to 8.
The finest Emeralds have historically come from the various Emerald mines of Colombia. Two classic old-world localities of Emerald are the Sikait-Zabara region, Egypt (known as Cleopatra’s Mines); and Habachtal, Salzburg, Austria. Other important Emerald deposits are in the Panjshir Valley, Panjshir Province, Afghanistan; Dayakou, Wenshan, Yunnan Province, China; Malyshevo, near the Tokovaya River, Yekaterinburg, Ural Mountains, Russia; the Byrud Emerald Mine, Minnesund, Eidsvoll, Norway; and the Rio Maria III Mine, Gité, Zambezia Province, Mozambique. Outstanding Emeralds, close in quality to those of Colombia, come from the Kagem Emerald Mine, Ndola, Zambia. This mine has been a recent producer of high-quality gem grade Emerald.
