OBSIDIAN CIGARETTE & CIGAR ASHTRAY | QUARTET173
Introducing the QUARTET 173, a handcrafted luxury stoneashtray 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 obsidian (volcanic glass), combined with crystal glass and brass, the ashtray reflects a controlled interplay between depth, transparency and metallic precision. The square architecture reinforces stability and visual clarity, 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.
Obsidian establishes the material identity through its dense, reflective surface, creating a deep and stable visual base. 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
Obsidian (Volcanic Glass). Origin: Armenia
Obsidian is a naturally occurring volcanic glass formed by the rapid cooling of lava. Its smooth, reflective surface and dense structure create a unique visual depth and tactile quality.
Each piece of obsidian reveals subtle variations in tone and internal structure, making every ashtray inherently unique. Its historical use in tools and objects underscores both its durability and material significance.
EXCLUSIVITY & HERITAGE
G.P.Grant develops designer objects based on natural stone, where structure and material define both form and function. The signature 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.
