Product Description
This semi mount engagement ring is designed for those who want full flexibility without starting from scratch. Crafted as one of the most refined semi mounts for round diamonds, it features a secure basket setting with a detailed criss cross basket setting structure that supports the center stone while elevating it in a graceful high profile engagement ring silhouette. The center is held in a protective double prong setting (also known as a double claw prong setting) for added security and a refined finish, making it ideal for a future round diamond engagement ring with hidden halo.
Beneath the center stone sits a delicate secret halo diamond ring detail, also called an invisible halo diamond ring, featuring 0.1 carat total weight hidden halo setting diamonds (1/10 carat diamonds). These lab grown diamonds are placed in a subtle common prong setting, adding brilliance from the side view while keeping the top appearance clean and solitaire-inspired. From above, it maintains the elegance of a solitaire ring with hidden halo, while the sparkle is revealed only at certain angles for a sophisticated touch. The sleek 2.2mm engagement ring band keeps the look minimal and balanced.
As a solitaire semi mount, this piece offers the perfect middle ground between a fully custom design and a ready-made ring. It allows you to choose your exact cut, carat weight, and stone type, whether you prefer traditional diamonds, lab grown diamonds, or an alternative to a diamond engagement ring such as sapphire or another gemstone. It’s also ideal if you already own a loose diamond and want to reset it into a modern style. Part of the Ouros Jewels semi mount engagement ring collection, this blank ring setting gives you cost control, faster customization, and the freedom to create a deeply personal engagement ring.
