If a diamond is cut too deep or too shallow, it will leak light and result in a loss in brilliance. Once all 57 facets are polished, the diamond will be sent for inspection. If it doesn’t meet the standards of a brilliant cut diamond, the stone will be sent back to the cutter to correct.
Is it difficult to cut a diamond?
Though diamonds are one of the hardest materials in the world, the cutting process is extremely delicate as one small incorrect angle could drastically impact the diamond’s final value.
Why is it hard to cut a diamond?

Each atom is a set distance from the next, and moving two of them closer or further away requires sudden and extreme force. This makes the diamond incredibly hard and is why it is able to scratch any other material.
