Product Description
This ring is built around a bold portuguese cut diamond, known for its layered faceting that adds depth and movement when viewed from every angle. The center is a 5 carat oval lab grown diamond, carefully chosen for its size and balanced outline. Created from a loose oval diamond and finished as a laboratory grown diamond, the stone reflects modern craftsmanship while keeping a responsible origin. Designed as a solitaire ring for engagement, it keeps the focus on the center while allowing small details to quietly enhance the look.
The diamond is secured in a precise 6 prong setting with refined claw prong setting work, forming a secure prong set diamond ring that protects the edges. Beneath the center sits a soft hidden halo setting, crafted with melee diamonds and tiny diamonds, giving the feel of an invisible halo ring without adding height. This construction keeps the ring comfortable as part of low set engagement rings and low setting diamond engagement rings, finished with a clean plain engagement ring shank. Designed as a portuguese cut diamond engagement ring, this piece fits confidently among big diamond engagement rings, made for those who want presence without excess.
