Valuable gem stones were found among tools that the early humans used during the Balangoda civilization which is considered to be over 30,000 years old.
Sri Lanka’s gem industry has a very long and colourful history. Sri Lanka was affectionately known as Ratna-Dweepa which means Island of Gems. The name is a reflection of its natural wealth. Marco Polo wrote that the island had the best sapphires, topazes, amethysts, and other gems in the world. Ptolemy, the 2nd century astronomer recorded that beryl and sapphire were the mainstay of Sri Lanka’s gem industry. Records from sailors that visited the island state has said that they brought back “jewels of Serendib”. Serendib was the ancient name given to the island by middle–eastern and Persian traders that crossed the Indian Ocean to trade gems from Sri Lanka to the East during the 4th and 5th century. It is also said that King Soloman had procured a great Ruby for the Queen Sheba from Ceylon.
Among the several world famous gems Sri Lanka’s blue sapphire weighing 456 carats is supposed to be the largest known sapphire in the world. Other famous gems include the Blue Giant of the Orient, weighing nearly 500 carats and the Bluebell of Asia.which weighs in at 400 carats.
