The Ocean Heart | Edo-Style Hand-Cut Crystal Whiskey Tumbler

Edo-Style Faceting Heritage without the Traditional Retail Markup

Inspired by historic Edo Kiriko cold-cut glass artistry, the Ocean Heart tumbler is individually mouth-blown and diamond-wheel faceted by our master crystal cutters. By shipping directly from our artisan studio to your lounge, we eliminate traditional multi-tier gallery markups, delivering authentic ~480g heavyweight heirloom craftsmanship at an honest atelier price.

The Ocean Heart: Fluid Arcs & Crystalline Waters

Capturing the dynamic cadence of ocean swells, sweeping clear ribbons cut diagonally across intricate geometric star lattices. When filled with spirits or backlit by ambient evening light, the tumbler sparkles with luminous aquatic refractions.

Two Radiant Editions: Aquamarine Blue & Royal Amethyst Violet

Available in sunlit Aquamarine Blue or regal Amethyst Violet. Both variations feature two-tone molten casing permanently fused over pure optical crystal, offering distinct personalities for personal contemplation or evening hosting.

Arcs of Light: Diamond-Smoothed Flowing Ribbons

Wide clear ribbons with sharp leaf cuts spiral upward around the cup body. By selectively grinding through the tinted outer casing, master cutters reveal the crystal-clear glass beneath to create intense contrast and visual depth.

Hand-Cut Star Web (Hoshi & Nanako Lattice)

Interlocking geometric stars and diamond lines are cold-cut entirely by hand. Every turn of the tumbler catches a different angle of ambient lighting, creating a sparkling mosaic across the palm.

One-Piece Radiating Multi-Petal Base

The solid foundation features a single-center multi-petal radiating floral incision. Crisp geometric facets project outward from the inner bowl through to the bottom, anchoring the ~480g tumbler firmly on your coaster.

Smooth Rounded Rim & Wide Tapered Form

Sculpted with thick, solid crystal walls that feel substantial and authoritative in hand. The wide, fire-polished rim glides comfortably across the lips, directing complex aromatic whiskey bouquets straight to the senses.
