Description
The Amber Diamond Edo Kiriko Whiskey Glass is a warm and refined crystal tumbler defined by rich amber color, precise hand-cut texture, and a brilliant faceted surface.
Its upper section features delicate starburst cuts that catch the light with crisp clarity, while the lower body is covered in diamond-like geometric facets that create depth, reflection, and a jewel-like glow. The amber gradient moves from soft golden tones near the rim to a deeper whiskey-like warmth toward the base, giving the glass a luxurious and balanced presence.
With a 6.4 fl oz capacity and a solid 11.4 oz weight, this tumbler is well suited for whiskey, bourbon, neat pours, cocktails, or refined home bar display. Its compact shape and rich faceted texture make it especially suitable for collectors and gift buyers looking for a handcrafted crystal piece with classic warmth and visual impact.
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.
