Jan-Maree Oliveira is the creator and designer at JMO Jewellery. After discovering her love for jewellery and precious stones at a young age, she became a qualified trade jeweller with over fifteen years of experience in the industry. 


Inspired by the forms, textures, and colours of her surroundings, Jan-Maree expertly crafts every piece with thoughtful consideration and a focus on wearability.


Using traditional techniques, she allows her designs to be guided by the way the elements harmoniously find each other on her work bench. The result is a one-of-a-kind collection that is always eye-catching, expressive, and meaningful.
