An American has discovered a new type of diamond that changes color according to temperature. The discoverer of this type of gem, Stephanie Persaud of the Gemological Institute of America, called the diamond "chilled diamond."
This type of diamond is characterized by its color turning from gray to yellow when the weather is very cold.
The value of this diamond is still undetermined, but it is expected that it will be very expensive due to its rarity.
The New Scientist website indicated that diamonds change color when exposed to temperatures of minus 196 degrees Celsius.
The reason for the change in the color of the diamond is still a mystery, given the possibility of the existence of more than one mechanism associated with this transformation, in addition to its rarity, which reduces the chances of studying it and conducting extensive experiments on it by scientists.
