Color Enhanced Blue Diamonds
Color enhanced blue diamonds start in the earth. They are earth grown and mined, just like a natural fancy colored diamond. Unlike it's rare cousin, however, the color enhanced diamond goes through a treatment process which changes the tone of the diamond. This is a permanent and internal treatment; it is not a coating.
Color enhanced blue diamonds are not available in light pastel tones. They have deep rich colors, with a green overtone, giving them a sparkly, turquoise ocean feel.
Lab Created Blue Diamonds
Lab created blue diamonds are grown in a laboratory, not in the earth. They are identical on a molecular level as natural diamond, therefore they have the same hardness and internal characteristics as a natural diamond. Read more about lab created diamonds here.
The blue color of a lab created diamond is more natural than the color of a color enhanced blue diamond. Although there is still a limited availabliity, the colors range from very light blue to a medium blue, all in the natural blue hues found in earth created blue diamonds.
