A greenish-gray ring may appear around a hard-cooked egg yolk. It’s unattractive, but not harmful. The ring is caused by a chemical reaction involving sulfur (from the egg white) and iron (from the egg yolk), which naturally react to form ferrous sulfide at the surface of the yolk.
Why did my eggs turn GREY?
The greenish-gray color is visual evidence of the formation of iron sulfide where the yolk and white parts of the egg meet. It happens because the iron from the yolk reacts with hydrogen sulfide from the white when it’s been overcooked. Totally harmless, but it doesn’t have to happen.

What does a GREY egg mean?
The gray layer is caused by a reaction between the iron in the egg yolks and sulfur in the whites. When the eggs are cooked too long or at too high a temperature, they form a drab compound called “ferrous sulfide.” You might also notice a distinct sulfury odor when you peel the eggs.
