PRMAL’s Exciting Pop-Up Event at Isetan Shinjuku

Lab-grown diamond jewelry brand PRMAL is thrilled to announce a temporary pop-up event at Isetan Shinjuku, opening its doors from March 18 to March 24, 2026.

Event Details

The pop-up store is located on the second floor of Isetan Shinjuku’s main building, specifically at "The Stage #2". Visitors will have the chance to explore PRMAL’s full lineup, including novel pieces from the iconic "Letter Collection", which features new products debuting in 2026.

What are Lab-Grown Diamonds?

In recent years, lab-grown diamonds have gained momentum as a viable alternative to natural diamonds, particularly amid increasing awareness around the United Nations SDGs and sustainable practices. These diamonds are essentially synthetic yet consist of the same chemical properties as their natural counterparts, making them indistinguishable from mined diamonds even to professional gemologists in many cases. They are produced through advanced techniques that replicate the natural diamond formation process, yet they are created in sustainable and controlled lab environments.

PRMAL’s commitment to environmental stewardship is encapsulated within its ethos. The brand focuses on lab-grown diamonds that reflect enhanced ethical standards without compromising beauty or quality. Additionally, by overseeing the entire production process, PRMAL aims to eliminate unnecessary costs that can inflate prices in the jewelry market, thus offering diamonds of optimal value.
