Description
The Sapphire Arc Edo Kiriko Whiskey Glass is a striking crystal tumbler that combines vivid blue accents with warm golden highlights and precise hand-cut craftsmanship.
Its body features detailed starburst and lattice-style cutwork, creating a brilliant reflective surface from every angle. Sapphire blue accents appear through the carved panels and lower arched sections, adding depth and contrast against the clear crystal body. Subtle golden tones along the rim and base bring a refined, luxurious warmth to the overall design.
With a 220 ml / 7.4 fl oz capacity and a solid 310 g / 10.9 oz weight, this tumbler is ideal for whiskey, bourbon, Japanese whisky, old fashioned cocktails, or spirits served neat or over ice. Its compact size and decorative structure also make it suitable for display, collecting, and premium gifting.
Each glass is individually hand-cut, so slight variations may occur from piece to piece. These natural differences are part of the character of handcrafted crystal glass and make every item unique.

The Craft, in Four Steps
Design Drafting
Each pattern is drawn by hand, mapping how light will travel through every facet.
Initial Cutting
Diamond wheels carve the primary facets. One wrong angle and the piece is lost.
Fine Adjustment
Each facet is refined by hand. Depth, edge, angle - adjusted until geometry becomes art.
Final Polishing
Progressive abrasives bring out optical clarity. Light passes through without distortion.
Why Optical-Grade Crystal?
Our crystal isn't just "glass." It's optical-grade borosilicate - the same material used in telescope lenses and camera prisms, chosen for its extraordinary clarity and precision.
When we set out to make the perfect whiskey glass, we didn't start with tradition. We started with a question: What if the same crystal that helps us see the stars could hold the amber glow of your favorite whiskey?
The result is a glass with >92% light transmission - higher than traditional lead crystal - and a hardness that allows for incredibly precise hand-cut facets. It's lighter than lead crystal, yet more durable and chemically stable.
This isn't a cheaper alternative to crystal. It's a better one.
| Attribute | Optical Crystal (ours) | Lead Crystal | Ordinary Glass |
|---|---|---|---|
| Light Transmission | >92% | >90% | ~85% |
| Refractive Index | High | High | Low |
| Lead Content | Lead-free | 24%+ | 0% |
| Weight | Lighter | Heavier | Light |
| Cut Precision | Excellent | Good | Poor |
