Product Description
This east to west oval engagement ring is a bold and modern ring setting only (no stone), designed for those who want a unique horizontal silhouette. Crafted as an oval diamond semi mount, the center is positioned in a sleek east west setting engagement ring style, creating a contemporary twist on classic oval engagement rings with halo. The secure 4 prong setting holds your chosen center stone firmly while keeping the look refined and minimal from the top view, making it ideal for a future oval lab grown diamond engagement ring or other gemstone centerpiece.
Surrounding the center is a striking double halo engagement ring design, featuring round lab grown diamonds on double halo setting. The first halo includes 0.2 carat, while the second halo adds 0.4 carat, totaling 0.6 carat diamond halo setting brilliance. This layered sparkle creates the look of a luxurious double halo oval ring and enhances the perceived size of the center stone. The band maintains a smooth, clean structure similar to a simple band with oval diamond, while the slightly bold base gives a subtle hollow signet ring feel for added presence without excessive weight.
As a semi mount for oval diamond, this piece is ideal for customization. It allows you to choose the exact cut, carat, and type of center stone, whether you prefer lab grown diamonds, colored lab grown diamonds, or other lab grown gemstones. It’s also perfect for colored diamond ring designs, gemstone engagement rings, precious stone engagement rings, or even non diamond engagement rings if you are looking for a beautiful substitute for diamond. This semi-mount offers a middle ground between a fully custom ring and an off-the-shelf design, helping you control your budget while pairing a meaningful loose stone into a modern east west oval diamond engagement ring setting.
