e.m. Marunouchi Offers Twelve Birthstone Colors for Jewelry March 7 to 31

e.m. Marunouchi will stage a limited-time Birth stone COLOR SELECT event from March 7 to March 31, 2026, offering customers the chance to choose from twelve birthstone colors to personalize jewelry. The boutique-branded event presents a narrow, three-week window for selecting color-driven options across the store’s jewelry assortment.

The program was announced March 3 ahead of the March 7 start, giving collectors and first-time buyers a brief planning period before the event opens. The March 7-31 schedule means the initiative runs through most of March, closing on March 31, 2026, and places all customization activity squarely within that fixed calendar span.

Central to the event is the availability of twelve distinct birthstone colors for personalization. Customers may pick among those twelve colors to be set into jewelry pieces at e.m. Marunouchi during the Birth stone COLOR SELECT event; the brand’s language emphasizes color choice as the defining customization parameter rather than broad remake or bespoke design services.

The tight March 7-31 timeframe is notable for shoppers who value limited runs. A three-week activation is shorter than seasonal launches that run for months, which concentrates demand and can make particular colorways harder to secure late in the month. For patrons who favor picking a specific hue, the event’s specified dates create a clear window for in-person selection and purchase.

From an editorial perspective, the Birth stone COLOR SELECT places color and personalization front and center but leaves unanswered questions that matter to discriminating buyers: the research notes specify twelve birthstone colors but do not detail whether stones are natural, lab-grown, treated, or accompanied by any certification. For buyers who prioritize provenance or gemological documentation, that absence of detail suggests verifying stone origin and certification at the time of selection during the March 7-31 event.

Practical takeaway: shoppers who want a color-personalized piece should plan to visit e.m. Marunouchi between March 7 and March 31, 2026, to choose among the twelve birthstone colors offered through the Birth stone COLOR SELECT event. The limited run and the specific twelve-color palette define this event’s scope and make the March dates the decisive factor for anyone seeking a custom-color piece.
