Description
The Emerald Starburst Edo Kiriko Whiskey Glass is a refined crystal tumbler defined by its vibrant green tone, crisp hand-cut craftsmanship, and striking geometric symmetry.
At the center of the design is a brilliant starburst motif, framed by diamond lattice cuts and smaller star accents that create a vivid interplay of light and reflection. The rich emerald color gives the glass a fresh jewel-like presence, while the clear crystal base adds brightness, balance, and a sense of weight. The overall look is both decorative and clean, making it a versatile piece for drinking, display, or gifting.
With a 7.1 fl oz capacity and a solid 9.1 oz weight, this tumbler feels comfortable yet substantial in the hand. It is well suited for whiskey, bourbon, cocktails, and refined home bar styling. The crisp patterning and luminous green tone make it especially appealing as a collectible or gift-worthy crystal piece.
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.
