Hearts on Fire…

Founded in 1996 by Glenn and Susan Rothman in Boston, Hearts on Fire became the world's first branded diamond, the only diamond in the entire world whose diamond is deemed perfectly cut every single time.

About the Designer:

Ilaria Lanzoni, the Hearts On Fire Director of Design, lived in S.Daniele del Friuli, a very small town in the Northeast of Italy that is about 1.5 hours from Venice for the first 18 years of her life. From there, she moved to Rome to study jewelry design for several years before also spending time in both Florence and Turinhas. Before joining the Hearts On Fire team, Ilaria was the Senior Designer for Garrads Fine Jewelry in London, England where she worked closely with Stephen Webster on a wide variety of design projects. Prior to Garrads, Ilaria designed for Asprey Fine Jewelry in London and helped launch a multitude of their collections.


In 2012, Ilaria quickly established two hit collections in her first year with Hearts on Fire – Copley and Illa – both of which have distinctive inspiration. The Copley Collection was created from Ilaria’s experiences during her first weeks as a new Boston resident, where she was enthralled by the city’s unique architecture and ironwork. The Illa Collection, named after Ilaria herself, was inspired from her love of the nighttime sky in Italy as a young child, and features beautiful constellation and star themed designs.

In 2013, Ilaria added two additional collections - Atlantico and Lorelei - which continue to integrate modern design elements into the brand. Both of these collections extend Hearts on Fire’s desire to marry diamonds with current fashion trends, including bold yellow and rose gold metals, as well as provide women with the aspiration to layer different Hearts on Fire necklaces, bracelets and more across the various collections. 

In 2014, Ilaria added a fifth designer collection to Hearts on Fire - the Aerial Collection. This beautiful collection reflects elements of nature that originate from or live in the air – including snowflakes, butterflies, suns, raindrop and more. This collection also uniquely uses optical illusions – taking only Hearts on Fire round diamonds to create the illusions of other diamond shapes, such as marquise and pear shapes.

Hearts on Fire Method and Manufacturing:

Diamond cutting by hand…starting with a selection of less than one tenth of one percent of the world’s rough diamonds. We then entrust them to less than 400 master craftsmen in the world who use a diamond cutting formula that is unknown to any other diamond brand in the world. And we cut and polish at 100x magnification – 10x the industry standard – to ensure our sparkling perfection each and every time.
