The Stellar Prism is defined by clarity and precision.
Cut from pure, transparent crystal, this Edo Kiriko whiskey glass reveals a disciplined star-cut pattern that radiates outward in perfect symmetry. Each facet is carved to exact angles, allowing light to pass through cleanly and break into sharp reflections — like points of light scattered across a night sky.
As the glass turns, the surface shifts between brightness and shadow, creating a quiet, constellation-like shimmer without excess ornament.
Minimal, balanced, and deliberate, it brings a sense of order and calm presence to any bar or interior.
Edo Kiriko Hand-Cut Stellar Prism Crystal Whiskey Glass
Mastery Carved into Every Facet
Edo Kiriko preserves a 190-year Tokyo legacy, where master artisans hand-cut Japanese crystal whiskey glasses through a rigorous six-step process. Using traditional grit wheels instead of industrial molds, we transform raw crystal into sharp, light-refracting prisms that define authentic craftsmanship.
The Breath of Life - Blowing
Molten glass is heated to over 1500°C and hand-blown into form. For colored pieces, multiple layers are fused together and annealed for more than 16 hours to ensure strength and stability.
The Blueprint - Marking
Reference lines are drawn by hand, creating a grid that guides every future cut.
The First Cut - Rough Carving
Guided by years of intuition rather than machines, the artisan uses a coarse diamond wheel to carve the initial bold patterns. This stage requires immense physical strength and a steady hand to define the soul of the design.
Refining the Spirit - Fine Carving
Switching to finer grinding wheels and natural whetstones, the craftsman meticulously refines every line. This stage transforms raw cuts into delicate, light-refracting textures.
Precision Detailing - Detailing
The final intricate motifs are hand-carved with microscopic precision. This is where the artisan’s true skill shines—creating a mesmerizing play of light that defines authentic Edo Kiriko.
The Final Glow - Hand-Polishing
Instead of chemical dipping, we use traditional rubber and cloth wheels with specialized polishing compounds. This labor-intensive manual polish preserves the sharp edges of the carvings while bestowing the glass with its signature brilliant luster.
Each JR piece is uniquely hand-blown and sculpted. Subtle ripples, tiny bubbles, or pattern variations are not flaws—they are the "fingerprints" of the master craftsman, authenticating a truly handmade work of art.
