RED JASPER CIGARETTE & CIGAR ASHTRAY | QUARTET173
Introducing the QUARTET 173 in Red Jasper, a handcrafted luxury ashtray defined by a four-point geometric structure and precise material assembly. This piece is composed of 173 individual elements, including 45 gemstone cubes, 84 crystal elements, 40 brass wedges and 4 removable holders, forming a balanced and clearly defined composition.
 
Crafted from natural red jasper, combined with crystal glass and brass, the ashtray reflects a controlled interplay between mineral density, transparency and metallic precision. The warm red and terracotta tones of jasper introduce depth and visual stability, while natural variations ensure that each piece remains unique.
 
The square architecture reinforces clarity and proportion, positioning the object as both a functional accessory and a sculptural centerpiece.
 
The detachable ash bowl ensures effortless cleaning, while the four removable magnetic holders allow flexible use for cigars or cigarettes without disrupting the structure.
Designed for refined interiors, the QUARTET 173 elevates the smoking ritual through material precision and architectural discipline.
 
The QUARTET 173 is defined by a four-point geometric configuration, organizing the ashtray into a structured square composition. Each side functions as part of a unified system, maintaining balance and clarity across the form.
Red jasper establishes the material identity through its dense structure and natural tonal variation, creating a stable and visually rich surface. Crystal elements introduce controlled light interaction, while brass wedges provide structural definition and contrast.
The integrated magnetic holder system is embedded within the architecture of the object, preserving clean geometry while enabling functional flexibility. This positions the QUARTET 173 as a compact collectible ashtray defined by structural clarity and material precision.
 
THE ARTISTRY OF MATERIALS
Red Jasper
Red jasper is a dense natural stone known for its deep red to terracotta tones and layered internal structure. Its surface reveals organic variations in color and pattern, creating a distinctive and expressive material identity.
Each piece of jasper is inherently unique, with natural differences that cannot be replicated, reinforcing its value as a material-driven element in high-end design.
 
EXCLUSIVITY & HERITAGE
G.P.Grant develops designer objects based on natural stone, where structure and material define both form and function. The ashtray collection reflects a disciplined approach to craftsmanship and engineering.
Each piece is assembled from multiple components, requiring extensive manual work and resulting in limited production. This process ensures a high level of precision and a strong material identity.
The combination of rare materials and controlled construction positions these ashtrays within the category of collectible objects, defined by authenticity, craftsmanship and long-term value.
