In this post, we’ll look at the world of Ceylon gemstones, including history, qualities, prices, and tips on how to identify them and where to buy them.

The History of Ceylon Gems

Historically known as Ceylon, Sri Lanka has a long and illustrious history in the gemstone industry. For centuries, Sri Lanka has been recognised for its vast quantities of precious and semi-precious stones, such as sapphires, rubies, and topazes. Royalty, nobles, and collectors worldwide have cherished these jewels for their beauty and rarity, and they have played a significant part in the country’s economy and culture.

From almost 2,500 years ago, gemstone mining and trade have been a part of Sri Lanka’s history. For example, according to ancient traditions, King Solomon is reported to have received a beautiful ruby as a gift from the queen of Sheba, who may have gotten the gem from Sri Lanka. From that point forwards, jewels from Sri Lanka were greatly coveted and sold globally.

Throughout the classical period of Sri Lanka, from the third century B.C. to the thirteenth century A.D., the gem industry flourished under the patronage of the governing monarchs. The court recruited experienced artisans and lapidaries to cut and polish the jewels, which were fashioned into gorgeous jewellery and other decorative artefacts. Several of these artefacts have survived to the present day and may be viewed in museums and private collections throughout the globe.

The entrance of European invaders in Sri Lanka in the 16th century presented the diamond business with new prospects and problems. The Portuguese, Dutch, and British understood the significance of the country’s jewels and wanted to dominate their production and commerce. The Dutch East India Company, which ruled Sri Lanka from 1640 until 1796, founded a diamond market in Ratnapura, one of the country’s most significant gem trade hubs.

Sri Lanka’s gem industry enjoyed a period of modernisation and development during the British administration, which lasted from 1796 until 1948. The Brits brought new mining techniques, such as hydraulic and tunnelling, which increased production and efficiency. In addition, they built a licence and regulating system, which helped kerb illegal mining and smuggling.

Today, Sri Lanka is renowned as one of the world’s leading suppliers of high-quality gemstones, with an industry that employs thousands of people and produces substantial cash for the nation. While mining processes have grown more sophisticated and controlled, most of the job is still performed by hand using old techniques passed down through the centuries. As a result, the country’s gems continue to be sought after by collectors and connoisseurs worldwide due to their rich hues, remarkable clarity, and natural beauty.

The Process of Gem Mining 

In Sri Lanka, gemstone mining has been a historical activity since the time of the ancient monarchs. Traditional, environmentally friendly, and ethical mining techniques used under the regulatory oversight of the National Gem and Jewellery Authority have established several milestones in the international Gemstone Mining Arena. Additionally, traditional mining techniques that have been refined over generations have been the main factor in Sri Lanka’s low mining accident rate.

Pit – Head Mining and Tunneling is the most popular Gemstone mining technique in Sri Lanka. The two extensively utilised techniques are Surface Placer Mining and River Bed Dredging. The National Gem and Jewellery Authority has created a range of industry-friendly laws and regulations to elevate and improve the quality of life and living standards of the Gemstone Mining Community. As obligatory employment requirements controlling the Mining Industry, mechanisms such as life insurance plans, accident and disability compensations, mortality, and academic scholarships for youths have been implemented.
