What’s the difference between an IF (Internally Flawless) and FL (Flawless) diamond? FL is an overall assessment not only referring to cleanliness but also to other parameters, especially to the quality of the cut. According to one study, one in five thousand diamonds is rated as FL.
When I searched for a 1 ct stone for this unique ring, there were only two such jewels available for sale worldwide, certified as FL by a renowned GIA institute. At the request of the client, I chose the better one. It was completed with small diamonds, with a total weight of 0.50 ct in 750 white gold.
