Description
The Cut’s Story
Gem cutting moved slowly for centuries — then in 1977, a diamond cutter named Henry Grossbard did something impatient: he combined the rectangular elegance of the emerald cut with the fire of the brilliant cut, in a single hybrid nobody had managed before. He called it the Radiant cut, and it became the first new diamond shape in decades — the youngest classic in the jewelry book. The Aqua Radiant Starburst is our translation: the radiant’s cornered geometry and the starburst’s radiating facets, cut into luminous aqua crystal, and set at the top of the Signature line where it belongs. It’s the glass for people who respect tradition but didn’t come to repeat it — the same spirit that made a cutter in ’77 decide the old shapes weren’t enough.
Craft & Material
Hand-cut aqua crystal with radiant-cut corner geometry and starburst faceting — the most complex cut in the Signature line, finished with our highest polish standard. The aqua body is at its most saturated in the base, opening as it rises.

FAQ
What’s a radiant cut?
A 1977 gem-cut innovation — the first successful hybrid of emerald-cut geometry with brilliant-cut fire. The youngest “classic” cut in jewelry.
Why is it the most expensive Signature glass?
It’s the most complex cutting in the line — more facets, more passes, our tightest QC. You can feel the difference in the hand and see it across the room.
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 K9 optical crystal — selected for its exceptional clarity, brilliance, and precision.
When we set out to create a better whiskey glass, we looked beyond tradition and focused on one thing: light. We wanted a crystal that could reveal the natural color and character of your whiskey through every precisely cut facet.
The result is crystal chosen for clarity and brilliance, shaped by hand and polished by skilled craftsmen. Its optical properties allow light to travel through the glass beautifully, while its hardness supports the crisp, precise cuts that define every Cristamor design.
Crystal for clarity. Crafted by hand. Designed to make the light shine.
More than a glass — crafted to make the moment shine.
