the brand story:

RBCCA KSTR was founded in 2015 by Rebecca Koster after humble beginnings in her share house living room. Rebecca's passion for producing sustainable jewellery drove her to launch her Australian label.  Her focus has been on guilt free minimalist jewellery and she's dedicated to giving her customers lust worthy designs with minimal impact on the environment; finding eco friendly replacements for the toxic chemicals traditionally used in silversmithing. All RBCCA KSTR pieces are made from recycled materials.
