Answer 2

Sapphires are mined from alluvial deposits or from primary underground workings. Historically, most sapphires have been mined in Sri Lanka, Madagascar and Myanmar. Australia leads the world in sapphire production (as of 1987) specifically from basalt derived placer deposits in Queensland and New South Wales. Pakistan, Afghanistan, India, Tanzania and Kenya also produce sapphires. The US state of Montana has produced sapphires from the Yogo Gulch deposit near Helena. Gem grade sapphires and rubies are also found in and around Franklin, North Carolina, USA. Several mines are open to the public.

Answer 3

Australia and Africa are the world's largest suppliers of blue sapphires. Sri Lanka also provides a large portion of the world's supply of blue sapphires. Gemstones from this island are often called "Ceylon" sapphires, which was the name of the island before it was changed to Sri Lanka. Pailin, Cambodia, is another source of exceptional blue sapphires. Burma is also known for their top quality supply of this gemstone.

Intense medium dark blue is the most sought after color for blue sapphires. However, very fine sapphires are extremely rare. Sri Lanka, Cambodia and Burma produce very fine pure blue sapphires, although Cambodian sapphires are sometimes slightly dark. Australian sapphires tend to have green overtones and concentric hexagonal bands. Midnight blue sapphires have traditionally been looked down on but today midnight blue sapphire jewelry is increasingly common - particularly for sapphire earrings.

Answer 4

Minas Gerais, Brazil. Also Australia. Sri Lanka is an important historical source.
