Pure Grown Diamonds are graded to the same specifications as mined diamonds and accompanied by Diamond Grading Reports from leading independent laboratories such as the International Gemological Institute (IGI).
These certificates are identical to mined diamond certificates including grading of the 4C’s along with full disclosure of the grown diamond origin.
A laboratory grown diamond is man-made but features the same optical and physical properties as a natural diamond including its chemical composition, refractive index and 4C’s. The only difference is its point of origin as one is grown above ground while the other is extracted from the ground.
Pure Grown Diamonds have our diamonds certified by an independent third party. Every one of our diamonds one quarter (1/4) carat and larger come with a Diamond Grading Certificate from the International Gemological Institute (IGI), New York. In addition to providing all of the diamond grading information, IGI also laser inscribes the certificate number and “Lab Grown” on the girdle of the diamond, further confirming our grown diamond’s origin.
