Free Shipping: On all orders over $50
The Stellar Ascent is an Edo Kiriko hand-cut crystal whiskey glass defined by a radiating starburst base and layered vertical cuts that extend upward through the body of the glass.
As light enters through the base, reflections move across each precisely cut facet, creating depth, contrast, and changing highlights from every angle. The fully transparent structure allows the geometry of the cuts to remain the visual focus, emphasizing both clarity and precision.
Crafted from high-clarity K9 crystal glass, the tumbler offers substantial weight, a stable base, and a comfortable grip. Designed for whiskey and aged spirits, it also serves as a sculptural display piece where light can fully engage the form.
Edo Kiriko Hand-Cut Stellar Ascent 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.
