Bellevue became the world’s first gold mine to achieve net-zero onsite Scope 1 and 2 emissions, ahead of its 2026 target.
Each 12 creation can be traced back to the exact mine from which its gold originates through a documented chain of custodial practices.

An independent dataset tracks environmental and ethical performance directly at the mine level.
In 2025, sales of SMO gold reached over £1.4 billion, with mines generating twelve tonnes of responsibly sourced gold globally.
Each 12 creation is accompanied by precise documentation, verifying the origin and transit route of the gold to your hands.
