Aqua Starburst Prism Artisan Cut Whiskey Glass – Hand-Cut Crystal Tumbler
$109
The Aqua Starburst Prism Artisan Cut Whiskey Glass brings a refreshing blue glow to traditional hand-cut crystal craftsmanship.
Description
The Aqua Starburst Prism Edo Kiriko Whiskey Glass brings a refreshing blue glow to traditional hand-cut crystal craftsmanship.
Its bright aqua tone gives the glass a clean, luminous look, while the detailed geometric cutting creates depth from every angle. The body features layered diamond textures, hexagonal starburst patterns, and sharp prism lines that reflect beautifully under light. At the base, a radiant floral star cut adds a striking finishing detail, making the glass just as impressive from below as it is from the side.
With its compact 6.4 fl oz / 190 ml capacity and substantial 12.3 oz / 350 g weight, this glass feels solid and refined in the hand. It is ideal for neat whiskey, Japanese whisky, bourbon, small cocktails, or as a collector’s piece for anyone who appreciates detailed crystal glassware.
Each glass is individually handcrafted, so slight variations may occur. These natural differences are part of the character and beauty of hand-cut crystal glass.

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.
