Gemaceuticals™ Grading Scale

Unlike diamonds, colored stones do not have a universal grading scale. One reason for this is because of the diversity and variability of all colored stones. Not all are graded equally, and each stone has its unique grading criteria. At Gemaceuticals™ we grade on both gemological and therapeutic grading criteria. The system we use for the therapeutic quality categories is shown below.  The majority of the gemstones we offer you at Gemaceuticals™ begin at Exquisite and reach to Exquisite +++.
