Product Highlights
Dual Hidden Sparkle (Halo & Bridge): The Pecs Oath features a brilliant hidden halo collar that underscores the main diamond, paired with a gorgeous row of micro-pavé diamonds on the structural bridge beneath it. Together, these accent stones maximize side-profile light entry to create a spectacular crossfire of light.

Elegant Cathedral Shank: High-sloping cathedral arches sweep upward toward the center crown. This iconic silhouette structurally reinforces the head, framing the center stone proudly while allowing your wedding band to rest completely flush.

Half-Eternity Pavé Band: The slender 2.0 mm shank is 50% covered with glittering diamonds running down the shoulders. This half-eternity style ensures optimal frontal sparkle along the finger while leaving a smooth gold base at the bottom for effortless resizing and maximum comfort.

Timeless Four-Prong Security: The classic 4-prong configuration holds your selected lab-grown center stone firmly in place, maximizing surface area exposure to optimize light performance and fire.
