Cut is the most important of the four C’s. The cut of the stone directly relates to the sparkle and beauty of the stone. Goldsmith Co. highly recommends purchasing in the GIA Excellent to Very Good range on cut. This level of perfection in cut renders the most brilliance in your diamond. When she looks down at her finger, the sparkle (cut quality) will be the thing that will continue to dazzle her year after year. (Just like you.)
