We only use diamonds graded S1 or higher ( VS ), called "Eye-Clean" where any inclusions are invisible to the naked eye. We only use diamonds graded Colorless ( D to F)  or Near Colorless ( G to J ). All of our diamonds used are full-cut and are graded 'very good' or 'better' on the standardized scale. The total carat weight used will be listed on the product page.
