Sapphire gemstones are precious gemstones that have been highly prized for centuries. It is a variety of the mineral corundum, which is composed of aluminum oxide. When you hear the word sapphire, you start visualizing many stories from past to present. Sapphire is typically blue, although it is found in other hues such as yellow, pink, and green but red. The journey of sapphire gemstones from mine to market can be long, complex, and thrilling. The process involves multiple steps and stages. Be with me to explore every destination of the journey of sapphire from mines to market.
Sapphire Gemstones: Mining
Sapphire miningThe first step in the journey of sapphire gemstones is mining. Sapphire is primarily mined in countries such as Sri Lanka, Madagascar, Myanmar, and Thailand. Depending on the location, the type of deposit being mined and the availability of resources, the mining process can be modern or traditional. In some places, sapphire is mined using traditional methods such as hand-digging and panning for alluvial deposits. In other cases, modern techniques such as open pit mining and underground mining are used to extract sapphire from the rock deposits.
Sapphire Gemstones: Sorting And Grading
Once raw sapphire is mined, it goes through the hands of professionals for the sorting and grading process. This involves separating the rough sapphire into different categories based on many factors such as size, shape, color, and clarity. Loose sapphire is then graded according to the four Cs: carat weight, color, clarity, and cut. This grading process helps to determine the value of the sapphire and its suitability for use in jewelry.
Sapphire Gemstones: Cutting And Polishing
After the sapphire has been sorted and graded, it is ready to be cut and polished. This process requires precision, highly skilled labor, and expertise. The rough sapphire is first sawed into smaller pieces and then shaped into the desired shape using a series of grinding and polishing wheels. The sapphire is then polished to a high shine using a series of finer polishing wheels. This process can take several weeks or even months to complete because it is a daunting task to transform a raw crystal into a fine gemstone with symmetric facets and minimum inclusions.
Treatment
In some cases, sapphire gemstones may undergo treatment to enhance their color or surface perfections. Heat treatment is the most common form of treatment for sapphire, involving exposing the gemstone to high temperatures to improve its color and clarity. Other forms of treatment include irradiation, fracture filling, and diffusion. To ensure fair business practices, gemstone dealers and buyers need to disclose any treatments that have been performed on a sapphire.
Certification
Once the sapphire has been cut, polished, and treated (if necessary), it is ready to be certified. Gemstone certification is a process that involves evaluating the quality and authenticity of a gemstone. The certification process is performed by an authorized gemological laboratory, which examines the sapphire using different instruments and techniques. The certification provides valuable information about the sapphire’s characteristics along with mining sources, treatments done to the gemstone, and details of the 4Cs.
Marketing And Sales
After the sapphire has been certified, it is ready to be marketed and sold. Sapphire gemstones are typically sold through a variety of channels, including gemstone dealers, jewelry manufacturers, and auction houses. You might have heard about a famous sapphire ring which is a replica of Princess Diana’s sapphire ring. All such jewelry pieces demand high-quality sapphires. The price of sapphire can vary widely depending on many factors, such as its transportation cost, labor charges, taxes, and duty, etc. Fine quality sapphires can command prices of tens of thousands of dollars per carat.
In recent years, ethical sourcing and sustainability have become increasingly important considerations in the gemstone industry. Many companies are now working to ensure that their sapphires are ethically sourced and that mining practices are environmentally responsible. The involvement of blockchain in the gemstone industry has made it easier to track gemstones to their source. Consumers are also becoming more aware of these issues and are seeking out sapphires that have been mined and processed responsibly.
In conclusion, the journey of sapphire gemstones from mine to market is a complex process that involves multiple steps and stages. It involves skilled labor, professional gemologists, and experts in the market and legal framework. The certification process ensures that the sapphire is of high quality and provides valuable information to buyers. As the demand for ethical sourcing and sustainability continues to grow, the gemstone industry is working to ensure that sapphires are mined and processed responsibly. Every time you purchase a gemstone, make sure that it is obtained by ethical mining practices and without any harm to the environment.
