The MaryLu 4.5 Carat Radiant Lab Grown Diamond F VS1 Cathedral Cigar Band Ring

The MaryLu. 4.5 Carats. Radiant Cut. Cathedral Setting. The Kim, Elevated.

The MaryLu is The Kim's cathedral chapter — the same iconic 4.5 carat radiant cut lab-grown diamond, graded F color and VS1 clarity, on the same bold 5.5mm cigar band with double-claw prongs, now elevated on a cathedral setting that lifts the stone higher, creates a more dramatic profile, and adds an architectural grandeur that makes The MaryLu unmistakably its own ring. If you love The Kim and want more presence, more height, more statement — The MaryLu is your answer.

The Stone

The radiant cut combines the clean rectangular lines of an emerald cut with the fire and sparkle of a round brilliant — the best of both worlds in a single stone. At 4.5 carats, the radiant's large face-up surface area creates a presence that is impossible to ignore. F color appears absolutely white and brilliant in any setting and any light. VS1 clarity means inclusions are invisible to the naked eye and extremely difficult to detect even under magnification.

The Setting

The cathedral setting is the defining difference between The MaryLu and The Kim — graceful arched shoulders that elevate the center stone above the band, creating a dramatic side profile and a more formal, elevated presence. The 5.5mm cigar band and double-claw prongs remain — the bold, architectural foundation that made The Kim iconic — now with the added drama of a cathedral silhouette. Available in 14k white gold.
