Sin is a Toronto-based jewellery designer, goldsmith and gemologist, who specializes in custom fine jewellery. She began her jewellery journey in 2004, learning technical skills in a 3-year Jewellery Arts program. In 2010, Sin's namesake business, Sin Kim Jewellery, was born. We strive to be environmentally and socially conscious in the purchase of our materials and the creation of our products.  Each piece is carefully crafted using only precious, ethically sourced gems, from trusted suppliers. Our metal is often recycled and purchased from local refineries and casters, who share our views on sustainability and push for positive impact.  Jewellery should be worn and loved and created so that it has quality and excellence, along with handmade charm. 

We believe in the history and romance that jewellery has always signified. In a world of fast fashion, we wish to be part of the antidote. Our jewellery is created to be timeless, treasured, future heirlooms. We put a lot of heart into each hand finished piece. They will represent cherished memories to be shared and passed down for generations to come. Custom jewellery made by Sin Kim is locally designed, and produced, specifically for its wearer. Sin works closely with her clients to interpret their stories, memories, messages ,and personal preferences. She incorporates them into her designs, as small thoughtful details. This process ensures that the rings are not just beautiful and well made, but personalised and heart felt.
