ZEUDIAS｜ゼウディアス at Dotonbori, Osaka

Kansai's first lab-grown diamond jewellery concept store in Namba's Ebisu-bashi district.

ZEUDIAS is a jewellery concept store specialising in lab-grown diamonds, opened in November 2024 as the first direct retail outlet of Shokou Boueki (ShoKo Trade), a long-standing Osaka-based trader that has handled lab diamonds for more than five years. Located across the second and third floors of the Ebisu-bashi Plaza Building on Namba 3-chome, inside the lively Ebisu-bashi shopping street, it was the first store of its kind in Kansai - a bricks-and-mortar showcase for a more sustainable, fairly priced take on diamond jewellery. The range centres on lab-grown diamond rings, necklaces and selected pieces from partner brands such as Smiling Rocks, all built around the idea of "next-generation" timeless jewellery that cuts out middle layers to keep prices fair. Because the parent company sources loose lab diamonds directly from around the world and supplies them to Japanese jewellers, the staff here can speak with genuine authority about quality, grading and what you are actually buying. If you are in the market for a meaningful piece of diamond jewellery - a lifetime item, perhaps an engagement or anniversary ring - and want an ethical, well-priced alternative to mined stones, ZEUDIAS brings serious expertise right into the heart of Namba.
