G.P.GRANT Cube Ring Billiard XL Straight Platinum Jewellery Pipe with Sapphires and Diamonds
The G.P.GRANT Cube Ring Billiard XL is an exclusive jewellery pipe that combines a straight Billiard XL silhouette with a smooth Royal Black briar body and a platinum Cube Ring set with sapphires and diamonds. Developed within an exclusive collection of handcrafted pipes, it reflects an authentic proprietary shape shaped by precise geometry, deliberate proportion and the recognisable proprietary DNA of the Cube series.
 
Executed in the classic Billiard archetype, the pipe preserves the familiar relationship between bowl and stem while extending the line into a longer 170 mm XL profile. This change in scale gives the piece a more architectural presence and reinforces its identity as one of the brand’s unique and original shapes rather than a standard catalogue interpretation.
 
At the centre of the composition stands a solid platinum jewellery cube, fully integrated into the structure as a true jewellery component rather than a decorative band. The Cube Ring creates a direct architectural transition between the briar bowl and the mouthpiece, establishing a clear relationship between form, material purity and rarity.
 
Sapphires and diamonds define the gemstone composition of the platinum element. The vivid blue stones introduce concentrated colour within the restrained Royal Black palette, while the diamonds sharpen the geometry of the ring with a precise play of light. In this way, the precious stones are not treated as applied embellishment but as part of the structural language of the luxury pipe.
 
The bowl is crafted from Briar (Erica arborea) and finished in a smooth Royal Black surface that preserves the clarity of the elongated silhouette. The material gives visual weight to the bowl while allowing the platinum and gemstone section to remain sharply articulated at the centre of the design.
 
These exclusive handmade pipes move beyond the category of conventional smoking accessories.
 
The Cube Ring Billiard XL belongs to the world of jewellery pipes, fine pipes and artisan pipes, where sculptural form, precious material construction and high jewellery execution converge. Handmade in Italy as an ultra-exclusive jewellery pipe and singular collectible object, it occupies the highest tier of the global pipe market and belongs to the sphere associated with the world’s most expensive pipes.
 
The Cube Ring Billiard XL is a handmade jewellery pipe with a smooth Royal Black briar body and a solid platinum Cube Ring set with sapphires and diamonds. Its extended straight profile gives the classic Billiard form a stronger architectural character. Created as part of an exclusive collection of handcrafted pipes, it functions both as a refined smoking instrument and as one of the collection’s remarkable works of jewellery art. It can be configured for a 9 mm filter or for filter-free smoking.
 
THE ARTISTRY OF MATERIALS
Briar (Erica arborea) forms the bowl and is presented in a smooth Royal Black finish. Its dense visual presence anchors the elongated Billiard XL silhouette and provides the structural base of the pipe.
Platinum forms the Cube Ring, the central jewellery element integrated into the architecture of the piece. Its cool-toned surface establishes a crisp transition between the dark briar and the mouthpiece.
Sapphires create the blue gemstone composition within the platinum ring, introducing depth of colour and a concentrated visual accent.
Diamonds frame and accompany the sapphires, adding brilliance and definition to the geometric surfaces of the Cube Ring.
 
EXCLUSIVITY & HERITAGE
The Cube Ring Billiard XL expresses the G.P.GRANT approach to pipe design through a controlled dialogue between established archetype and proprietary form development. Its identity does not depend on ornament alone; it is built through structure, proportion and the integration of jewellery craftsmanship into the core of the object.
 
Each pipe is handmade in Italy and conceived as a one-of-a-kind creation. The platinum Cube Ring is not a secondary embellishment but an essential architectural feature that defines the character of the piece and links precious materials directly to the construction.
 
Positioned among exclusive pipes, collectible pipes and one-of-a-kind pipes, this model is intended for collectors who value irreproducibility, rare materials and uncompromising execution. It stands not simply as a smoking accessory, but as a singular collectible object within the field of works of jewellery art.
