Fancy blue diamonds are among the rarest of all naturally colored diamonds. The color originates from boron particles trapped within the crystal lattice during the diamond’s formation. Most fancy blue diamonds come from the Cullinan Mine near Pretoria in South Africa. Our loose certified natural fancy blue diamonds come in a brilliant spectrum of blue shades from softest sky blue, so you can find the perfect stone for your collection or your custom engagement ring.
