Diamonds can be found in shallow alluvial deposits where the crystals settle after being transported away from the kimberlite pipes by geologic activity and rivers. Diamond forms under high temperature and pressure conditions that exist only within a specific depth range (about 100 miles) beneath the earth’s surface Diamond’s crystal structure is isometric, which means the carbon atoms are bonded in essentially the same way in all directions. Diamond’s splendor has been appreciated for centuries, but there was not much scientific knowledge about it before the twentieth century Since then, diamond knowledge has grown steadily, with research by chemists, physicists, geologists, mineralogists, and oceanographers. Proper color evaluation is a matter of expertise
The correct way to evaluate diamond color is in precise conditions, under controlled lighting, where stones are compared to masterstones with established color grades From d for colorless to z for light. Gia’s diamond origin tells the story of how diamonds mined from these countries support jobs, education, and health care and in many cases, how they help protect the environment in and around local mining communities.
