Some lava doesn’t reach the surface. They stuck deep in the soil. So it is cool down slowly. They became crystallise and forms coarse-grained minerals.

That is the birth of gems. The first type of rocks, igneous are also born like above. They are originated from the crystallised of cooling interlocking magma crystals grow within the intrusive igneous rock and may form gemstone depending on the elements present, cooling time and the environment.

How can gemstone found 

Gems mining is an industrial deed. People who are finding gems in the mining as the job using very technical tricks to success. They are heavy machinery, hydraulic shovels, and trucks. They help to mine the gems from the kimberlite pipes. Colour gemstone mining is very difficult because it is rigorous and time-consuming. The reason for that is deposit are few and when found, tend to be crystallised by small quantities of gems. Modern technology that used to mining the gems is in very high quality and its deposit are often too small to be profitable for major mine outfit.

Who leaves them to small, independent miners who rely on the same manual techniques. They have been using for decades. Nevertheless, in recent years, several major mining companies have entered the gemstone market with new strategies for employing modern mining practice. The other important fact about the gems is establishing the value of a gemstone. As with gold gemstone counterfeits or synthetic gemstone can be mistaken for the real thing.
