Sri Lanka (Ceylon) Gems


The gems of Sri Lanka are woven in to his history. The Mahavansa, the ancient chronicle of Sri Lanka too mentioned about gems and jewelry. Indeed, the lord Buddha himself is sad to have had to come to Sri Lanka from India to settle a dispute between two kings, Chulodara and Mahodara, over a throne of gems.

King Soloman is reported to have had gems brought from this island to win the heart of beautiful queens. The great traveler, Marco Polo, was said to have been so awe struck by a priceless ruby in the possession of the king of Sri Lanka that the recorded it as been "span in length, with out a flow, brilliant beyond compare".

Sri Lanka became known as Ratna Deepa (The Island of Gems). Some of the rarest precious stones in the world are found in abundances in the reach earth under our feet and the hills above us. Among the several world famous gems Sri Lanka's blue sapphire weighing 466 carats, the largest known sapphire in the world. Weighing in at 19Kg was also discovered here. Other famous gems include the "Blue Giant of the Orient", weighing nearly 500 carats and the "Bluebell of Asia", which weights in at 400 carats. The renowned Sri Lankan star sapphire is on permanent display at he museum of natural history in New York, but due to an oversight, the stone has been called the star of india.

Throughout history Sri Lanka's gems and jewelry have adorned the crown jewels of many a royal family. A 105 carats cat's eye gemstone discovered in a paddy field in Sri Lanka, gained fame among the royalty of Britain and was successively admired by Edward VII, George V, Edward VIII, and Queen Elizabeth.

The process of mining for gems is begun at an auspicious time with a short religious ritual. The most common methods of mining are in pita and by tunneling. Surface gemming and dredging depends on the location and the type of deposits stones are normally found in a layer of coarse, pebbly material, which contains traces of clay and fine sand. This gravel containing gems are referred as to as "illama" and is found just below the alluvial deposits.

The rarest gem in the world alexandrite, is found in Sri Lanka.

Gem pits are of two kinds. The shallow ones are well shaped and circular, where as deep pits are rectangular. To prevent the walls of the pits from caving in scaffoldings are made and the spaces filled with leaves. The water is then pumped out of the pit. If the "illama" vein runs horizontally, tunneling has to be resorted to.

Another method of collecting "illama" is to place wooden poles across the river bed and standing on a pole with a long stick, a person drags the gravely sand towards him. This is then collected in buckets.

Either way the gravel is then washed in large circular wicker buckets by immersing them in water and rotating them. This enables the light, ordinary pebbles and sediment to escape, leaving the heavier pebbles behind. Then the basket are held against the sunlight and the sorting is carried out. Each illam brings forth a variety of stones. The principle source of Alexandrite, the rarest gem in the world is Sri Lanka it was first found in the Urals in 1830 and is named after Czar Alexander II who come of age on the day it was found. This stone shines green in natural light but turns raspberry red in artificial light. The cat's eye is another stones which is considered valuable and rare. It derives it name from fact that a silvery lines runs across its greenish gray surface, giving it a remarkable resemblance to the eye of a cat. The rarest type is the black cat's eye. Sri Lanka can host of having 17 varieties of precious and semi precious stone. The most notable are,
