About Bert Sieraden

We are Bertie & Renée, two sisters behind the brand and webshop Bert Jewelry. Bert Jewelry was founded by Bertie, who has had a passion for designing and making jewelry since she was 16, and in 2021 Renée joined to support. Bert Jewelry is especially known for the one and only "heart bracelets" for both adults and kids. What makes our jewelry extra special is the use of gemstones. We love that each stone is unique in color and shape. We also find the energy that these stones emit very special.Read their story
