Description
The Cut’s Story
For most of history, diamonds were dull — until cutters in the 1600s discovered that a stone’s job wasn’t to be pretty but to manage light: catch it, bend it, and throw it back in concentrated flashes. The “brilliant cut” that emerged — its starburst pattern of angled facets radiating from a central point — remains the standard every engagement ring on earth still uses, because nothing has ever beaten it at making light behave. The Emerald Starburst brings that geometry to the glass in your hand: a star of facets at the base, radiating through deep emerald crystal, firing green sparks across the table when the lamp hits. Jewelers work a year to put one starburst on a ring. You get to drink out of yours.
Craft & Material
Hand-cut crystal in emerald green with brilliant-cut starburst geometry — radiating facets from a centered point, the same light-management math jewelers use.
A Gift That Means Something
Engagement-season gifts, anniversaries, and anyone who’s ever been proposed to under a jeweler’s lamp. The starburst is diamond language; this is its spoken translation.
FAQ
What’s a starburst cut?
It’s the facet arrangement from gemstone cutting — angles radiating from a center point, designed to gather light and return it as flashes. Jewelers call the effect “fire.”
Is this related to the Noir Diamond Starburst?
Same geometry, opposite personality — that one’s black and rebellious; this one’s emerald and classic. Collectors argue about which pours better.
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.
