About Us

Hello. My name is Konstantinos I. Leoussis and I am the owner of KIL N.Y.C., a company specializing in antique jewelry from the late Stuart to Edwardian era as well as a jewelry line greatly inspired by antiques, my travels, and world history. As a jewelry collector of many years, I understand that buying online and circumnavigating the antiques community can be daunting for some.

I strive to make buying jewelry online a comfortable experience and I spend time searching for the right pieces to add to my inventory. After years of experience working under the tutelage of jewelry historians and as a former operations assistant of a fashion jewelry firm, I have honed my skills and I aim to create an entirely new type of jewelry business with a youthful and humanistic approach.

I strive to keep my business independent without investors and corporate influence, environmentally sustainable by reducing waste and utilizing recycled metals for my jewelry line. Supporting women and independently owned businesses and vendors is very important to the ethos of my company. We currently offer a range of antique jewelry, small vintage collectables, custom and bespoke jewelry, antique restorations and repairs as well as educational content about antique jewelry. Please note that most of our inventory sells fast through social media and most is not posted on our website so please contact us if there is something that you are looking for. 

All antiques are guaranteed to be accurately stated and we are happy to offer a very flexible layaway plan for most antique and vintage items. Should you require any additional information or simply want to reach out, we would love to assist you in any way possible.
