Ensuring that the condition of your cards are correctly represented by the grade on the encapsulation is essential in determining value. Accuracy and consistency define our approach to grading and we are confident that our encapsulations will hold up to the intense scrutiny of the card collecting market. The 20 year history with our prior label (BSG Grading) has proven that the grades we issue are industry trusted representations of a cards true condition.

As a card grading company, Diamond Service Grading strives to eliminate as much subjectivity as possible in our grading process. Our graders assess any damage or flaws on the corners, edges, surfaces and centering and record the level of that damage on each of 8 zones (4 front zones, 4 back zones) in our proprietary software grading program (Patent Pending). These scores are calculated to produce the true and accurate grade that your card deserves.
