Description

The Toyo-Sasaki Kurotama Gold Cold Sake Set brings together clear Japanese glass, deep ink-like accents, and real gold foil detailing in a refined sake set made for quiet enjoyment and elegant gifting. Made in Japan by Toyo-Sasaki, the set includes one sake carafe and two matching sake cups, offering a complete presentation for chilled sake, fruit sake, plum wine, or other cold drinks.
The design is centered around a dark “kurotama” sphere-like motif, suspended within the transparent glass like ink resting in water. Fine vertical lines run through the carafe and cups, giving the set a calm sense of rhythm, while scattered real gold foil adds a soft metallic shimmer. As light passes through the glass, the gold catches gently against the black accents, creating a look that feels understated, luxurious, and quietly ceremonial.
Each piece is made using semi-red crystal glass with a smooth, transparent finish that allows the colour of sake to remain visible. The carafe features a recessed inner chamber that can hold ice, helping keep sake chilled without diluting its flavour. This makes the set especially practical for cold sake service, allowing the drink to stay refreshing while preserving its original aroma and taste.
The sake cups are shaped with a wide, flared mouth and a stable thickened base, giving them a comfortable hold and a balanced feel on the table. The clear glass body, black linear pattern, and real gold foil details create a refined contrast that works beautifully for both modern and traditional table settings.
Presented in a wooden box, the Kurotama Gold Cold Sake Set is suitable for gifting, entertaining, or personal use. Its combination of Japanese craftsmanship, practical chilled-sake design, and real gold foil decoration makes it a thoughtful choice for sake lovers and collectors of Japanese glassware.

▶ The Craft, in Four Steps

01

Design Drafting

Each pattern is drawn by hand, mapping how light will travel through every facet.

02

Initial Cutting

Diamond wheels carve the primary facets. One wrong angle and the piece is lost.

03

Fine Adjustment

Each facet is refined by hand. Depth, edge, angle - adjusted until geometry becomes art.

04

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.

Frequently Asked Questions

Q1: What is "optical-grade crystal"?
Optical-grade crystal is a high-clarity, lead-free crystal glass formulated for maximum light transmission and refraction. It's the same quality used in premium lenses and prisms - which is why our glasses catch light so beautifully. (Yes, it's sometimes called K9 in manufacturing. We just prefer to talk about what it does, not what it's called.)
Q2: Is each glass really hand-cut?
Yes. Every facet is cut by hand using diamond-impregnated wheels. No two glasses are perfectly identical - slight variations are part of the craft and proof of authenticity.
Q3: How does the free engraving work?
Select "Add Personalization," enter your text, and we'll engrave it before shipping. Engraving takes 2-3 business days. There's no extra charge - personalization is included with every glass.
Q4: Can I put these in the dishwasher?
We recommend hand washing with mild soap and a soft cloth. The hand-cut facets can be dulled by harsh dishwasher detergents over time. Think of it like a good knife - hand care keeps the edge.
Q5: Are these safe for hot drinks?
These glasses are designed for spirits and cold beverages. Rapid temperature changes can stress the crystal, so please avoid hot liquids.
Q6: How long does shipping take?
Standard shipping: 5-10 business days. Express: 3-5 business days. Personalized items add 2-3 business days for engraving. Q4 holiday cutoffs are posted on each product page.
Q7: What if my glass arrives broken?
We pack each set with triple-layer protection. If anything arrives damaged, send us a photo within 7 days and we'll send a replacement - no need to return the broken piece.
Q8: Do you offer bulk or corporate pricing?
Yes. For orders of 10+ sets, contact us at hello@cristamor.com for volume pricing and custom branding options.
