These diamonds are at the bottom of the barrel as far as quality, clarity, cut and so on. Enter the statement may have been treated and they are a bad buy all around. I would feel terrible knowing I bought a diamond that may fall apart on my girlfriend when she cleans them, or if they lose their sparkle due to any coatings, laser drillings that may fall out over time. Do your homework and buy a book "How to buy a diamond". You will not regret what you learn about your next purchase on a quality diamond. Insist on non treated stones. They are a worthwhile investment for you or your loved one.
