Single Mine Origin Gold (SMO Gold)

Single Mine Origin Gold

Single Mine Origin (SMO) Gold is a revolutionary global benchmark for the Gold and Jewellery trade. Single Mine Origin Gold guarantees Responsible, Ethical, and Transparent mining practises as well as full Traceability of Gold to a single mine – currently the Hummingbird-owned Yanfolila mine in Mali, West Africa.  SMO-Certified Gold exclusively remains segregated and trackable from mines to refining to the making of the final piece of jewellery with an auditable chain of custody.  SMO carefully follows a number of strict standards in line with the World Gold Council’s responsible Gold Mining Principles as well as its own social and environmental responsibility initiatives.

The SMO principles and their collective sustainability programmes deliver humble benefits to the local communities around the Gold Mine. Education, Healthcare, Safe drinking water and Agricultural prosperity Initiatives are some to name, which all bring great support to a wide number of people and societies. The SMO mining operation also eliminates all ties to conflict, where miners are being paid the right wage under secure employment.

Essentially every piece of SMO Gold Wedding Rings and  SMO Certified Gold Jewellery offers peace of mind that the gold has been produced with outstanding Industrial, Environmental, and Social Standards to benefit us all. At Autumn and May, we take great pride to craft SMO Gold Wedding Rings and SMO Gold Bespoke Commissions, in which the Gold can be traced back to a single mine.

Where is your gold came from..?

Most of you may not know where the gold in your jewellery comes from. We aim to be more thoughtful of the materials by using Single Mine Origin Gold – SMO states the exact Gold Origin and Gold Mine information. Your Wedding Ring or Engagement Ring created with a Mined Origin Gold will always have an SMO Gold mark along with the traditional British Assay Hallmarks. The SMO mark applied by the British Assay Offices is an assurance that the gold has been produced by the legitimate SMO standard of mining operation.

Each piece of Autumn and May Wedding Rings and Engagement Rings made of SMO gold comes with a traceable QR code supplement card.  Scan the QR Code with your smartphone and get to know the information and origins of the gold used in your jewellery. This allows you to truly explore the gold’s provenance and the impact of each transaction has helped to create local community efforts.
