Searching for Chrysoberyl Cats-Eye Stones in Sri Lankas Gem-Rich Rivers
Sri Lanka, renowned for its vast deposits of gemstones, is a paradise for rockhounds and mineral collectors. Among the treasures found within its gem-bearing rivers is a rare and exquisite gemstone known as chrysoberyl cats-eye. This unique mineral, famous for its remarkable chatoyancy–a phenomenon where a band of light moves across the surface–attracts collectors and enthusiasts alike. This article explores the intricacies of searching for chrysoberyl cats-eye stones in Sri Lanka and provides practical insights for aspiring gem hunters.
The Allure of Chrysoberyl Cats-Eye
Chrysoberyl is a beryllium aluminum oxide mineral that occurs in two forms: ordinary chrysoberyl and its more coveted variety, cats-eye. The chatoyancy effect in chrysoberyl cats-eye arises from the presence of fiber-like inclusions, such as rutile, that reflect light. This striking display can exhibit shades of green, yellow, or brown, with the highest-quality stones displaying a sharp, well-defined eye.
According to gemological studies, the best chrysoberyl cats-eye stones can command prices ranging from $100 to $5,000 per carat, depending on factors like color, clarity, and the strength of the cats-eye effect. Also, cats-eye stones weighing over 5 carats with a strong phenomenon can significantly outperform standard gems on the market.
The Rivers of Sri Lanka
Sri Lankas extensive river systems, particularly in regions like Ratnapura and Elahera, are rich with gem-bearing sediments. The composition of these rivers, primarily alluvial deposits, creates an ideal environment for gem formation and discovery. Gem hunters often find chrysoberyl cats-eye stones in gravel beds and along riverbanks, where natural erosion has exposed these hidden treasures.
- Ratnapura: Known as the City of Gems, Ratnapura is famous for its rich deposits of sapphire and chrysoberyl, making it an essential destination for gem collectors.
- Elahera: This area is especially known for various types of gemstones, including chrysoberyl. Specimens can often be found near the riverbanks.
Techniques for Finding Chrysoberyl Cats-Eye
Searching for chrysoberyl cats-eye gemstones requires a blend of knowledge, skill, and intuition. Here are some practical tips for collectors on how to effectively search for these stones.
- Field Equipment: Equip yourself with essential tools, including a small shovel or trowel, a bucket for collecting gravel, and a sifting screen for sorting through materials. A headlamp can also be beneficial for nighttime searches.
- Look in the Right Places: Focus on areas where the current is slower or where debris builds up, such as behind rocks or natural benches along the river. e spots are more likely to capture heavier stones like chrysoberyl.
- Be Patient: Gem hunting requires patience. Sift through several layers of gravel and sediment, as the work can be labor-intensive but rewarding.
Identification and Evaluation
Once you have collected potential chrysoberyl stones, its essential to identify and evaluate them. Here are key attributes to consider:
- Chatoyancy: The defining feature of cats-eye chrysoberyl is its chatoyant effect. Rotate the stone under light to observe the movement of the light band.

- Weight and Size: For collectors, larger stones often possess a higher value, especially if they exhibit a strong cats-eye effect.
