The reason why ruby ​​is expensive
Every ruby ​​has a high price, and the main reason is due to the difficulty of mining environment.
Ruby is produced in less places, mainly in Myanmar, Thailand, Sri Lanka, Vietnam, India, Tanzania, China and other places. Moreover, there is usually a saying that "ten treasures and nine cracks" means that most rubies have cracks, smashes, cracks, etc. Very pure and perfect rubies are very rare. Sapphire is mainly distributed in Myanmar, Thailand, Sri Lanka, the Bailin area of ​​Cambodia, Kashmir, India, Australia, Montana, China and other places.
Igneous rocks and metamorphic rocks are key factors in the formation of corundum gemstones. Secondary deposits originate from the most prone to mineralization of these main rocks. If so, we can look for gems in a more specific place in such a vast area.
Time-tested panning techniques are one of the most common and useful prospecting methods. Basically, it consists of exploring river grit. Due to the highly defined gravity of corundum, it is more commonly concentrated in rivers and creek riverbeds. Exploration includes sampling of river gravel layers and begins downstream of the river. When even very small corundum is found, people regularly work downstream from the downstream and sample along the way. Termination of anything is not discovered. Then the next step is to fold back to the exact location where the gemstone starts. From here, further sampling will be determined on the shores of the appropriate rivers and streams from the corundum.
As the demand for rubies rises, heavy equipment and complex prospecting methods are applied. Australia is one of the world leaders in the mining and exploration of corundum. In this series of processes, we need not only patience and careful screening, but more importantly, the test of our perseverance and perseverance. It is not difficult to imagine that the gradual selection of exquisite and beautiful gems from a large number of gravel is like a layer of sand and sand. This carefully selected work consumes a lot of manpower, material resources and time. When we finally get a gemstone with a shining brilliance, the most beautiful movement bearing the memory of the river is emerging in front of us. Rare and more precious.
Moreover, some gemstones are located on remote desert islands, with hot summers and severe winters. Some mines are located on cliffs, which seriously affects the mining of gem deposits and brings many difficulties to miners.
