Concrete Ring and Cufflinks by Konzuk; timeless designs, like the materials they’re made from. Stainless steel and concrete is not the first thing that comes to mind when you think of jewelry, but they are materials designer Karen Konzuk has mastered. Her concrete line is stunning, it utilizes a clean, minimal approach that is true to the materials, like modern urban architecture. After 5 years of use, these pieces look as good as new. The concrete will darken with time, and you’re bound to get scratches on the steel, but this only adds to the character of the piece. Konzuk also has a killer selection of women’s jewelry, so you may wanna consider your girlfriend or wife with your next purchase. Hand-made and designed in Canada. Check out the full concrete line.
