Description
The Blue Black Eclipse Edo Kiriko Whiskey Glass is a dramatic crystal tumbler defined by contrast, depth, and precision.
Its design combines deep cobalt blue, smoky black crystal tones, and a clear central cut-glass panel that creates a striking eclipse-like visual effect. The front-facing starburst cuts add brilliance and texture, while the surrounding geometric facets reflect light with a bold, architectural presence.
With a 8.8 fl oz capacity and a substantial 19 oz weight, this glass feels solid and luxurious in the hand. It is ideal for whiskey, bourbon, cocktails, or display as a statement piece in a refined home bar.
Each glass is individually hand-cut from crystal glass, so slight variations may appear between pieces. These subtle differences are part of the character of handcrafted glassware 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.

| Refractive Index | High | High | Low |
