What Gives Blue Diamonds Their Color?

The blue color in diamonds is caused by the presence of boron atoms within the crystal lattice.
In lab-grown diamonds, this occurs naturally during the CVD or HPHT growth process, when trace boron interacts with carbon creating shades that range from soft ice blue to deep sapphire tones.

💡 The boron atoms slightly alter how light passes through the diamond, producing that stunning cool hue while maintaining full brilliance.
