This archived Custom by Z design featured a natural round diamond with an F color grade and Flawless clarity at the center. Two round side diamonds, approximately 0.50 carat each, completed the three-stone arrangement in an 18-karat white-gold setting.

What Flawless clarity means
Flawless, abbreviated FL, is the highest grade on the GIA clarity scale. It means a skilled grader did not see inclusions or blemishes when examining the diamond under 10× magnification under the prescribed conditions. Flawless diamonds are rare, but clarity is only one part of a diamond’s overall appearance and value.
Where F color fits on the scale
On GIA’s D-to-Z color scale, D, E, and F are in the colorless range. An F-color diamond can present a bright, icy appearance, especially in white gold or platinum. The setting style, diamond shape, lighting, and neighboring stones can all influence how color appears to the eye.
Why choose a three-stone ring?
A three-stone engagement ring gives the center diamond extra presence while creating a balanced profile across the finger. Some couples also associate the three diamonds with the past, present, and future. Side stones can be matched closely to the center or selected in different shapes for contrast.
