The center diamond is certified by IGI or GIA. Graded E in color, VVS2 in clarity, and finished with an ideal cut, this cushion cut diamond offers fire, brilliance, and mirror-like depth.

This ring is handmade, and available in all ring sizes with full custom sizes available. It’s also fully sizable, so it can grow with you for years to come. The solitaire setting features a clean, 2mm band that keeps the focus on the 3.80 carat center stone, while the warm tones of yellow gold or the cool luster of white gold offer three metal options to match your personal style.

While this piece is brand new and made to order, it is sold without original tags or packaging. It comes with a physical certificate, and the diamond’s certification number is inscribed directly on the girdle.
