CUBE RING HAUTE JOAILLERIE PIPE | BESPOKE GOLD & PRECIOUS STONES
The Cube Ring Bespoke Jewellery Pipe is offered as a fully customizable architectural creation. Each piece is handcrafted according to your selected shape, briar finish, and gemstone composition, preserving the distinctive Cube design DNA while allowing individual expression.
Choose your preferred proprietary silhouette — Billiard Straight, Billiard Bent, Panel, Poker Straight or Poker Bent — each defined by disciplined geometry and balanced proportions.
At the centre of the construction stands the Cube Ring element, executed in precious metal and meticulously set with your selected gemstone composition: Diamonds & Sapphires, Diamonds & Rubies, Diamonds & Emeralds or Diamonds & Cognac diamonds.
Every configuration is made to order and individually produced. No two pieces are identical.
Product images are for reference only. The final piece may vary slightly due to handcrafted production and bespoke configuration.
The Cube Ring Bespoke Jewellery Pipe represents a fully customizable architectural pipe system developed by G.P.Grant. Conceived as a structured design object rather than a conventional smoking accessory, it allows the collector to define shape, material finish, and gemstone configuration while preserving the controlled geometry and proprietary Cube Ring identity.
Each piece is individually handcrafted and built around a central precious metal Cube Ring element, integrating high jewellery craftsmanship into the structural core of the pipe. The chosen silhouette — Billiard, Panel, or Poker — is executed with disciplined proportion and axial balance, ensuring architectural coherence across every variation.
Produced strictly to order, the Cube Ring Bespoke exists as a singular object. No configuration is repeated. Each pipe reflects the dialogue between personal selection and controlled design language, positioning it within the upper tier of collectible jewellery pipes rather than standard luxury tobacco pipes.
Filter System
Our pipes are designed for 9 mm filters and can be configured for filter-free smoking, depending on personal preference.
