Blue Sapphire Gems Jewellery

Sri Lanka’s gem industry has a very long and colorful history. Another name for Sri Lanka is Ratna-Dweepa which means Gem Island. 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 states that they brought back “jewels of Serendib”. They crossed the Indian Ocean to trade gems from Sri Lanka to the East during the 4th and 5th century.

Sri Lanka, geologically speaking is an extremely old country. Ninety percent of the rocks of the island are of Precambrian age, before 560 million years. The gems form in sedimentary residual gem deposits, eluvial deposits, metamorphic deposits, skarn and calcium-rich rocks. Nearly all the gem formations in Sri Lanka are located in the central high-grade metamorphic terrain of the Highland Complex now. The gem deposits are classified as sedimentary, metamorphic and magmatic; the sedimentary types being the most abundant. Now The mineralogy of the gem deposits varies widely with, among others, corundum (sapphire, ruby), chrysoberyl, beryl, spinel, topaz, zircon, tourmaline, garnet being common.

Residual deposits mainly found in flood plains of rivers and streams. The metamorphic types of gems constitute 90% of the gem deposits in Sri Lanka. It has been estimated that nearly 25% of the total land area of Sri Lanka is potentially gem-bearing. Sri Lanka is one of the countries with the highest density of gem deposits compared to its landmass.

Ratnapura contains the most gem deposits and derived its name from the gem industry. Ratnapura means “city of gems”.

Sapphire is the most precious and valuable blue gemstone. It is a very desirable gemstone due to its excellent color, hardness, durability, and luster. In the gem trade, Sapphire without any color prefix refers to the blue variety of the mineral Corundum.
