Crystal tableware produced in limited quantities, including wine glasses, flutes, tumblers and glassware for whisky, champagne and other beverages. Each piece is handcrafted with a focus on precision, balance and material clarity.
All items are mouth-blown, hand-cut and assembled in France, Italy and, in selected cases, Germany. This is not mass production, but controlled manufacturing based on traditional craftsmanship and technical execution.
All crystal collections are mastecraft, mouth-blown, hand-cut and classified into:
SPECIAL EDITION
-
Mastercrafted pieces, mouth-blown and hand-cut
UNIQUE EDITION: MASTERPIECES
-
These pieces, like all Unique Editions by G.P. Grant, are made as one-of-a-kind.
PERSONAL EDITION: BESPOKE CREATIONS

Completely Handmade Crystal
Crystal is produced entirely by hand in France and Italy, passing through multiple traditional stages that define its final quality and uniqueness.
The value of crystal is determined by a combination of material, process and limited production:
Materials
Crystal contains lead oxide, increasing density, brilliance and light refraction compared to standard glass.
Craftsmanship
Each piece is blown, cut, polished and finished by hand, requiring precision and technical skill.
Process
Production is time-intensive, often taking weeks to complete a single piece.
Finishing
Selected items include gold, platinum, engraving and colour-layered elements.
Production
Limited quantities or made-to-order pieces ensure controlled output and exclusivity.
Optical Properties
High light refraction creates clarity and brilliance, defining crystal quality.
CRAFTSMANSHIP PROCESS
CRYSTAL BLOWING
Molten crystal is shaped by hand at approximately 1200°C using traditional glass-blowing techniques. Artisans control rotation and airflow to achieve symmetry and define the initial form of each piece. This stage determines the structure, balance and optical properties of the final object
CRYSTAL CUTTING
After blowing and cooling, each piece is cut by hand using sandstone or diamond wheels. This stage defines the final form and creates surface patterns while maintaining structural precision.
Traditional techniques include Flat Cut, Star Cut, Panel Cut, Hobnail and Crosshatch, forming both classic and contemporary designs.
Advanced methods such as Diamond Cut and Brilliant Cut increase the number of facets, enhancing light refraction and optical clarity.
Selected collections incorporate Edo Kiriko, a Japanese hand-cutting technique based on layered crystal, where the outer coloured layer is removed to create precise geometric contrasts.
CRYSTAL POLISHING
After cutting, the surface is polished to restore clarity and remove tool marks. Two methods are used: chemical polishing, where the crystal is treated to enhance transparency, and mechanical polishing, where the surface is refined by hand using specialized tools. This stage ensures a smooth, reflective finish and prepares the piece for engraving or gilding.
COLOUR-LAYERED CRYSTAL
Colour-layered crystal is created by fusing a clear and a coloured layer using metallic oxides such as nickel, copper, chromium or cobalt. After forming, the outer coloured layer is partially removed through cutting, revealing the clear crystal beneath and creating contrast and depth.
This technique requires precise control of materials and temperature, resulting in multi-tone surfaces with enhanced light interaction.
CRYSTAL SANDBLASTING
Sandblasting creates a matte surface by projecting fine abrasive particles onto selected areas of the crystal. Masking defines the treated zones, allowing controlled removal of the surface to generate texture and depth.
CRYSTAL GILDING
Gilding applies gold or platinum to selected areas of the crystal through a controlled multi-stage process. After masking, precious metals are applied by hand and fixed through heat treatment, followed by polishing to achieve a refined finish.
Available finishes include rose gold, matte gold, polished gold, platinum and black chrome.
BRONZE WORK
Bronze components are cast in France and assembled by master craftsmen. The final structures are finished with 24-carat gold or platinum, creating a combination of structural strength and refined detailing.
Signature Designs and Collections
The collection combines contemporary design with European and Japanese glassmaking traditions, focusing on precision, balance and material clarity.
The range includes crystal wine glasses, flutes, whisky sets, tumblers, carafes and spinning glassware.
Custom-Made Production
We create bespoke crystal pieces from concept to final production. Shape, size, colour and decoration are defined individually, including engraving, logos and precious finishes.
Production may include the development of new moulds and structural elements. Each project is executed as a controlled, limited piece, not adapted from existing products.
