Sri Lanka’s Gem industry has a very long colorful history. Sri Lanka was known as “Rathna Deepa” which means Gems Island.the name is reflection of its natural wealth. So many historical incidence and the stories had written about precious stones of Sri Lanka. The Ptolemy an astronomer of the 2nd century AD recorded that beryl and sapphire was mainstay of Sri Lankan gem industry. And Famous business traveler of 13th century AD from Venice, the Marcopolo wrote that the island had the best sapphires, topazes, amethysts and other gems in the world. Furthermore the Records from the sailors of Middle Eastern and Persian traders that visited the island wrote that they brought back jewels of Serendib in 4th 5th century AD. even during the colonial period lots of gems are taken away from Sri Lanka. Sri Lanka has highest density of gem deposits compared to its land mass to find gem stones which known as gem mining are done by using few methods pit-head mining, and tunneling, Surface placer mining, and river bed dredging. Some people ride on their luck without any effort.
Anyway compare to the other parts the Ratnapura city and suburbs contain the most gem deposits in Sri Lanka. And derived its name from gem industry. Ratnapura means city of gems. There are lot of gemstone types can be found in Sri Lanka. the blue sapphire is the most famous, which known as Ceylon sapphire. Ceylon sapphires are reportedly unique in color, clarity and shine compared to the other countries. The Ceylon sapphire is the stone which fixed in the princess Diana wedding ring, the same ring has been used for the engagement of the prince William and kate. It is said the the blue saphire of Sri Lanka went almost out of stock at that time as everybody in England wanted a replica of it.
The biggest star sapphire has been founded recently in Sri Lanka which 1405 carrots. Corundum, beryl,quartz, spinel,tourmaline ,topaz are some of gem species that found in srilanka.
it’s very complicated to evaluate a gemstone, you need lot more experience to it, but basically we can look for 4 things to evaluate, which known as 4 C s. The color- depends on stone the value of the color varies. For example if its blue sapphire cone flower blue has market, if its darker or lighter has less value than corn flower blue, this sapphire can only found in Sri Lanka known as Ceylon sapphire. When it’s come to Ruby, pigeon blood red has market. The Clarity- there are inclusions in the stone, less inclusion has more values. Cut depend on the shape of stone cut varies. Carrot weight- bigger stones are very rare. Those stone has big values. We cannot calculate in the method of other things are calculated. For example if 1 carrot is equal to 10 dollars mens 10 carrots is equal to 100 dollars, but this theory is not valid for the gemstones, that ten carrot stone could be even 1000 or even more. Because again big stones are very rare. Any way even today Sri Lanka is exporting 100,000 carrots annually. Lot of international gem buyers also visiting Sri Lanka to buy gems. The government authority also provide supports and services to them if they approached. Such as checking the real quality of the stones, weighing, giving certification and etc. He government authority for gem industry is National gem & jewellery authority (NGJA) renamed in 1993, which originally had started in 1971 as state gem corporation (1971)
