Kamakura Store

Kamakura Store

Nestled in the historic streets of Kamakura, near the iconic monument of former Sri Lankan President J.R. Jayewardene, our gem store is more than just a retail destination—it’s a celebration of craftsmanship, sustainability, and innovation. At RURI Social Innovation Inc., we bring you exquisite natural gemstones and meticulously handcrafted jewelry that tell stories of ethical sourcing and refined artistry.

A Journey Rooted in Integrity

Our story begins far from Japan—in the lush, gem-rich landscapes of Sri Lanka. We import uncut gems directly from this world-renowned gem-producing country, ensuring that every gemstone carries the heritage and intrinsic beauty of its origin. At RURI, we believe that excellence and sustainability go hand in hand. That’s why our commitment goes beyond aesthetics; we work closely with miners, cutters, and dealers, as well as certification labs, governments, and IT leaders like Tracified. This collaborative approach ensures that every step of our supply chain is transparent and ethically sound.

The Art of Transformation

Once these raw, natural stones arrive in Japan, they are transformed by skilled artisans into stunning, one-of-a-kind pieces of jewelry. Each piece is handcrafted to order, merging traditional craftsmanship with contemporary design. By collaborating with acclaimed designers from Tokyo and around the globe, we not only enhance the allure of our jewelry but also nurture emerging talent in the industry. Our commitment is clear: to deliver high-quality, ethically sourced jewelry that resonates with modern aesthetics and sustainable values.

Embracing Technology for Transparency

At the heart of our operations lies a dedication to responsible innovation. Leveraging advanced DX and blockchain technologies, we ensure complete traceability of our supply chain—from the mines of Sri Lanka to our boutique store in Kamakura. This transparency not only builds trust with our customers but also guarantees that every piece of jewelry you purchase is backed by ethical practices and verified provenance. We believe that true luxury comes from knowing the story behind your jewelry—a story of respect for nature, culture, and community.

A Hub of Culture and Sustainability

Our gem store is ideally located in Kamakura, a city that marries rich cultural heritage with modern sophistication. Being just a stone’s throw away from the JR Jayawardana statue, our store offers visitors a unique blend of historical charm and contemporary elegance. Whether you are a seasoned collector or a first-time buyer, you will appreciate the seamless fusion of tradition and innovation that defines RURI.
