How long will a diamond last?

Originally Answered: How long do diamonds last? An average cut diamond is roughly 3–4 billion years old. Nothing lasts forever, over time it will degrade and decay due to entropy and turn into graphite but it will take billions of years more. In human timescale terms it will effectively last forever.
