Description
The Azure Crown Edo Kiriko Whiskey Glass is a refined crystal tumbler defined by crisp transparency, vivid blue accents, and a striking crown-like cut structure.
Its design features tall faceted peaks rising across the glass, creating a bold architectural rhythm. A subtle blue diamond band adds contrast and depth, while the surrounding lattice and starburst textures catch the light with sharp brilliance. The clear crystal body keeps the overall look clean and elegant, making the piece feel both decorative and timeless.
With a 9.8 fl oz capacity and a solid 11.9 oz weight, this tumbler is well suited for whiskey, bourbon, cocktails, or refined home bar display. Its combination of clear crystal, blue detailing, and sculptural hand-cut patterns makes it especially suitable for gifting, collecting, or premium table styling.
Each glass is individually hand-cut, so slight variations may appear between pieces. These subtle differences are part of the character of handcrafted crystal glass and make every piece 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.
