Product Description
This semi mount engagement ring features a bold geometric design inspired by pentagon cut diamonds and the distinctive silhouette of a dutch marquise engagement ring. Designed as a multi shape diamonds engagement ring, the halo is crafted with mixed diamond shapes arranged in a detailed halo setting engagement ring style. This artistic cluster layout symbolizes unity with individuality, representing a love that is dynamic, personal, and deeply layered. The elongated outline, influenced by elongated hexagon engagement ring aesthetics, creates a slimming, lengthening effect on the finger, making it ideal for those who prefer a confident, statement-making look.
The structure incorporates a refined martini setting that elevates the center stone position within a graceful cathedral setting engagement ring profile. This creates a striking high profile engagement ring appearance while allowing maximum light exposure. The knife edge band (knife edge shank) features a raised, angled ridge that enhances brilliance and gives the band a slimmer visual profile without compromising strength. This architectural detail complements the overall geometric diamond engagement ring and knife cut engagement ring aesthetic.
Sold as a without stone semi mount ring, this setting allows full customization of your center stone, whether you choose a 1 carat diamond engagement ring, all lab grown diamonds, or a unique gemstone alternative. The mixed halo design combined with elongated structure offers a modern alternative to traditional vintage style diamond engagement rings, blending historic faceting inspiration with contemporary form. It is ideal for clients who want personalization, flexibility in carat weight, and a semi-mount that stands out from conventional styles.
