What is the difference between heated and unheated Ruby?
1 Answer
A heated ruby is a ruby wherein 1600 - 1700 degrees centigrade of heat is applied to the stone to improve it's color, luster, and/or clarity. This is a common method for most rubies is not a bad at all.
What makes unheated rubies valuable is their rarity. To find a beautiful ruby that does not need heat to improve it's beauty is very rare and highly unlikely.
