About Kozi collections
Our Service Pledge
We respond to all orders within 24 hours, we guarantee the authenticity of all our items.About Us
Kozi is a third generation diamond dealers & estate buyers.Our passion starts from buying unique vintage to new age jewelry. Every piece has its own history or story behind it. Aside from buying estate jewelry we love designing our own pieces, mostly with natural gems and diamonds. We sell all estate and vintage as is, just the way we buy it, to keep its original vintage look and sometimes to keep its value, but we are more then happy to polish any purchased item if requested at no extra charge. Upon request we can send a live video of any item in stock. Please feel free to ask any questions you may have.
Thank you for visiting our shop.
