G.P.GRANT Cube Ring Billiard XL Platinum Jewellery Pipe with Diamonds
The G.P.GRANT Cube Ring Billiard XL is an exclusive handmade jewellery pipe distinguished by its extended 170 mm profile, smooth Royal Black briar and diamond-set platinum architecture. Its elongated straight format preserves the traditional bowl proportions of the classic Billiard archetype while giving the silhouette a more pronounced visual rhythm.
 
The XL construction establishes a deliberate relationship between the upright cylindrical bowl and the long tapered mouthpiece. Although rooted in a recognised pipe form, the integration of the Cube Ring gives the model an authentic proprietary shape and the clearly identifiable proprietary DNA of the G.P.GRANT collection.
 
A solid platinum Cube Ring occupies the structural centre of the luxury pipe. Fully integrated between the briar bowl and mouthpiece, it functions as a jewellery-grade component rather than a conventional decorative band. Its precise geometry creates a direct architectural relationship between form, material and rarity.
 
Brilliant diamonds cover the visible facets of the Cube Ring, introducing a controlled play of light against the Royal Black surface. Platinum and diamonds are incorporated as essential components of the composition, bringing high jewellery execution into the construction of the pipe rather than applying precious materials as superficial embellishment.
 
This handcrafted pipe combines fine pipe making, precious metal construction and gemstone setting within a functional object. It can be configured for a 9 mm filter or filter-free smoking, retaining the character of an artisan pipe while moving beyond standard smoking accessories and conventional luxury pipes.
 
Handmade in Italy as a one-of-a-kind creation, the Cube Ring Billiard XL belongs to the field of exclusive pipes, collectible pipes and singular works of jewellery art. Conceived for collectors of fine pipes and unique and original shapes, it occupies the category associated with the world’s most expensive pipes, where material purity, irreproducibility and high jewellery craftsmanship determine value.
 
The G.P.GRANT Cube Ring Billiard XL pairs an elongated Royal Black briar body with a solid platinum ring set exclusively with brilliant diamonds. Its 170 mm straight silhouette gives the classic Billiard form a distinctive architectural presence. Created as an ultra-exclusive jewellery pipe and singular collectible object, it combines functional design with the precision of high jewellery artistry. The model is available for 9 mm filter or filter-free smoking.
 
THE ARTISTRY OF MATERIALS
Briar (Erica arborea) forms the smooth Royal Black bowl and provides the material foundation for the elongated straight Billiard silhouette.
Platinum forms the solid Cube Ring integrated between the bowl and mouthpiece. Its geometric surfaces define the central architectural element of the pipe.
Diamonds cover the jewellery ring and create a precise luminous contrast against the dark briar and mouthpiece.
 
EXCLUSIVITY & HERITAGE
The Cube Ring Billiard XL reflects the G.P.GRANT approach to transforming established pipe proportions through proprietary jewellery architecture. The classic form remains legible, but its identity is decisively altered by the extended scale and geometric platinum structure.
Each piece is individually handmade in Italy, bringing together specialist pipe craftsmanship and diamond setting. The jewellery element is developed as part of the construction itself, ensuring that precious metal engineering and smoking function belong to the same design language.
Produced as a one-of-a-kind creation, this collectible luxury pipe is positioned at the absolute pinnacle of the pipe market envisaged by the collection. Its status is founded on singular production, solid platinum, brilliant diamonds and uncompromising high jewellery craftsmanship.
