Natural blue diamonds come from below the earth’s surface and are extremely rare. The steel blue tone of a natural blue diamond brings to mind a rolling deep sea, as opposed to other blue stones like aquamarine or sapphires, which are brighter like the sky or a tropical cove. Most blue diamonds found today have been treated with heat and have a brighter blue color. The natural stone gets its color from the trace of boron in the crystal lattice of the diamond. They have a slight hint of gray and will never be as bold and saturated in color as a gemstone like a blue sapphire.
The most famous blue diamond is The Hope Diamond, weighing 45.5 carats. Blue diamonds are found in a stunning light to deep blue color depending on the amount of boron present. As the color and carat weight increases so does the price.
