Description
The Black Butterfly Edo Kiriko Whiskey Glass is a bold and elegant crystal tumbler defined by its dramatic black tone and distinctive butterfly-inspired cut design.
Its standout feature is the large butterfly motif carved into the surface, framed by crisp geometric cuts that create contrast, brilliance, and depth. The dark glass body gives the piece a strong visual presence, while the hand-cut crystal detailing adds refinement and light-catching clarity.
Crafted from hand-cut crystal glass, this tumbler offers both artistic character and everyday functionality. With a 6.4 fl oz capacity and a weight of 7.6 oz, it is ideal for whiskey, bourbon, neat pours, and elevated cocktail service. Its sculptural appearance also makes it a memorable gift or a distinctive addition to a premium home bar collection.
Because each piece is handcrafted, slight variations may occur. These natural differences are part of the charm of handcrafted crystal glass and make every glass uniquely its own.
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 |
