Sapphire mining / මැණික් ඉල්ලම / srilanka Sapphire mining.

Sapphire mining involves the extraction of sapphires, which are precious gemstones belonging to the corundum mineral family. These gemstones can be found in a variety of colors, although blue is the most recognized. The mining process typically occurs in several stages: 1. *Exploration*: Geologists identify potential mining sites based on geological surveys and previous findings. 2. *Extraction*: Miners may use various methods, including open-pit mining, alluvial mining (extracting stones from riverbeds), or underground mining. Alluvial mining is particularly common in regions where sapphires are found in river sediments. 3. *Processing*: After extraction, the rough stones are sorted and graded based on quality. This includes assessing clarity, color, and size. 4. *Cutting and Polishing*: The gems are then cut and polished to enhance their appearance before being sold in the market. Countries like Myanmar, Sri Lanka, Madagascar, and Australia are known for their sapphire deposits. The value of sapphires can vary significantly based on their quality and origin. #Sapphiremining #slgaganabro #මැණික්ඉල්ලම
