THE DESIGN STORY
The Inspiration Effortless, refined, and meticulously made, the Osaka Oval Diamond Engagement Ring balances modern architectural strength with uncompromising minimalism. Designed for the modern collector who values clean-lined luxury, this striking solitaire piece relies on geometric balance and structural integrity rather than loud embellishment.
The Craftsmanship Custom-made to order in our private Auckland studio, the design features a signature minimalist 4-prong basket engineered specifically to maximize light return through a premium oval brilliant-cut lab-grown diamond. Sitting elegantly on a sleek, high-polish comfort-fit band, the Osaka ring is a bold, timeless statement of luxury and flawless New Zealand craftsmanship.
Designed by MOHSTEN. Crafted for you.
