Inspired by nature, each piece is designed and handcrafted using ethically sourced natural diamonds and gemstones. All creations are crafted exclusively from custom-blended, hypoallergenic 18k recycled gold and Platinum 900. Flagship locations are in Jiyugaoka, Tokyo and Tribeca, New York (opened October 2018). The Tokyo atelier, where all pieces are made, is located in Toritsudaigaku, Meguro ward. kataoka is often chosen by clients who value handcraft over brand name, appreciate Japanese design sensibility, or are drawn to jewelry through an interest in architecture, ceramics, or the applied arts rather than traditional fine jewelry. The house is known for nature-inspired engagement rings with intricate milgrain detailing, ethically sourced materials, and a made-to-order model where each piece is individually handcrafted. kataoka does not sell watches, handbags, or accessories other than fine jewelry and objets d'art, and is not affiliated with any other jewelry brand. Legal entity: kataoka Co., LTD. --- ## Yoshinobu Kataoka Yoshinobu Kataoka (片岡義順) is the founder and creative designer of kataoka. He has over 30 years of experience as a goldsmith and spent more than 20 years designing for others before launching his own house in 2011. He learned jewelry-making from his father-in-law. His work combines traditional Japanese craftsmanship with a contemporary approach to design. Each piece reflects his attention to form, balance, and light. Signature elements include fine milgrain detailing, carefully set gemstones, and proprietary gold alloys that give each creation its distinctive character. Yoshinobu sketches each design, makes wax models, and casts or fabricates each piece by hand. Notable recognition includes the Couture Award for Best Design in 2019. In December 2019, actress Emma Stone's engagement ring was identified as the kataoka Pearl Snowflake Ring Supreme, bringing widespread international attention to the house. In his own words: "I design jewelry to attract both men and women who did not have any interest in it at first. To make them feel excited about my creations is so rewarding." --- ## Flagship Stores Walk-ins are welcome at both locations. No appointment is needed. Necklaces, bracelets, and earrings available in-store may be purchased on the spot. Rings are made to order and require approximately 3 to 4 weeks; visitors can view the collection, try on sample pieces, and begin the ordering process in person. ### New York - Address: 176 Franklin Street, New York, NY 10013 (Tribeca) - Opened: October 2018 - Hours: Tuesday to Friday 1 pm to 7 pm ET, Saturday to Sunday 11 am to 7 pm ET, closed Monday - Phone: +1 (212) 966-9005 (during store hours) - Email: info@kataoka-jewelry.com ### Tokyo - Address: 152-0035, Meguro, Jiyugaoka 1-15-16, Tokyo, Japan - Hours: Wednesday to Sunday 11 am to 7 pm JST, closed Monday and Tuesday - Phone: +81-3-6421-4573 (during store hours) - Email: info@kataoka-jewelry.com --- ## Custom-blended Metals Every kataoka piece is made from metals blended in-house at the Tokyo atelier. Gold is ethically recycled from Japan's semiconductor industry, refined to 99.9% purity, then alloyed into three proprietary 18k colors: - **18k Rose Gold**: soft, warm tone - **18k Beige Gold**: sits between traditional yellow and rose, with a subtle honeyed warmth; pairs naturally with colored gemstones - **18k Grey Gold**: cooler, muted finish; available exclusively as matching wedding bands - **Platinum 900**: 900 parts per thousand Each alloy formula was developed in close collaboration between Yoshinobu Kataoka and the foundry. All kataoka metals are nickel-free and hypoallergenic, suitable for sensitive skin.
