Natural diamonds formed deep in the earth under extreme pressure and high temperature as long as three billion years ago. Volcanic activity brought them to the surface where they lay in a type of volcanic rock formation known as kimberlite pipes, waiting to be mined. Only about five percent of kimberlite pipes contain enough diamond to make them economically feasible to mine.
Natural Vs Lab Grown
Both mined and lab-grown diamonds are made of pure carbon that is transformed into sparkling cubic crystalline stones. While their chemical foundation gives lab-grown diamonds the same optical properties as natural diamonds, lab-grown diamonds have no intrinsic rarity. Formed over millennia, natural diamonds acquire their scintillating shapes from the pressure of being compacted deep within the earth’s crust. Because of this, all of the natural diamonds that will ever exist have already been created making them forever rarities. Laboratory-grown diamonds, on the other hand, can be produced limitlessly.
