in the fascinating realm of gemology, when we examine the formation of diamonds, we often underplay the significance of the pre-beginning stages where elements deep within the earth's mantle begin their journey towards crystallization. it's crucial to notice how, if we metaphorically go back to the start of this process, the conditions under-the-table, or rather beneath the earth's surface, set the stage for the creation of these precious stones. this phase, largely hidden from the naked eye, involves a remarkable transformation of carbon under extreme pressure and heat, culminating in the birth of diamonds we so highly treasure.
