The Diamond G4 darts, developed in collaboration with Kosuzu Iwao, redefine the Diamond series with a striking balance of beauty, precision, and high-level performance. This fourth-generation model reflects a bold, evolving design philosophy, highlighted by its signature triple diamond ring motif inspired by stacked jewelry rings. Each of the three rings features distinct groove depths and textures, creating varied grip zones that enhance control, reduce slipping, and allow players to naturally lock into consistent finger placement for a stable, repeatable throw. Accented with vivid red lines against a sleek black barrel, the design channels energy, confidence, and modern style while maintaining a refined, professional aesthetic that stands out both on the board and in hand.

Built with a straight barrel profile for versatility and balance, the Diamond G4 darts deliver smooth handling suited to both beginners and experienced players. The front section incorporates softened shark cuts for a controlled, responsive release, while the center integrates diamond-pattern cuts with ring grooves to provide precise tactile feedback and visual depth. The rear section features alternating mild shark cuts that offer a secure yet comfortable grip, ensuring stability without over-aggression. Carefully engineered across the entire barrel, this layered grip structure supports a wide range of throwing styles and promotes consistent performance. Combining fashion-inspired design with competitive functionality, the Diamond G4 is a powerful and stylish evolution that embodies brilliance, individuality, and precision in every throw.
