Established in 1931, the nonprofit Gemological Institute of America (GIA) is the world's foremost authority in gemology.

GIA's mission is to ensure the public trust in gems and jewelry by upholding the highest standards of integrity, academics, science, and professionalism through education, research, laboratory services, and instrument development.

Once a diamond is GIA or EGL certified, it cant be treated, if it was - it would have said so in the 'comment' section, it would say for example: 'lab created', or 'laser drilled', or 'color enhanced'- or any other similar remark to indicate that the stone is not natural. That's the whole point of buying a certified stone, especially GIA - the strictest in the world.

We recommend buying only certified stones (By GIA or EGL only....not any
other laboratory) and we also sell only certified stones. Once the stone is certified - you know exactly what you are buying, (real diamond, genuine, authentic with no imperfection), and there are no surprises of what you getting.

The best diamonds are diamonds that have been graded, preferably by The Gemological Institute of America (GIA), and all of our diamonds are certified, which means that you, as a buyer, are assured of their everlasting value and authenticity.
