S.P. International

​

Founded in Kofu, Yamanashi—Japan’s historic center for gemstone craftsmanship—S.P. International is a name built on trust, artistry, and over 30 years of experience in the world of gemstones and fine jewellery.

Our journey began with a deep respect for traditional techniques and a passion for quality gemstones. Over the decades, we have refined our expertise to create lightweight, handmade jewellery that blends timeless elegance with modern design. Each piece reflects careful craftsmanship, attention to detail, and a commitment to comfort and wearability.

At S.P. International, we also specialize in order-based and custom jewellery, working closely with our clients to transform their ideas into unique, meaningful creations. From gemstone selection to final finishing, every step is handled with precision and care.

As our reputation and reach grew, we expanded our business by opening an office in Tokyo, strengthening our connection with international markets while continuing to honor our roots in Kofu. Today, S.P. International stands as a bridge between tradition and innovation, serving clients with integrity, creativity, and a passion for excellence in jewellery making.
