Hearts On Fire is a diamond company with an impressive reputation. Their stones are considered to be the most perfectly cut diamonds in the world, showcasing exceptional fire and brilliance.

The brand prides itself on excellence in sourcing, cutting, craftsmanship and design, and it’s little wonder that Hearts On Fire is in serious demand. Countless celebrities have been spotted wearing it, including RihannaKate Upton and Julia Roberts.

Today, we want to take a look behind the Hearts On Fire curtain, discovering more about their history, diamonds and some of the highlights from their impressive collections.

Come with us, and step inside Hearts On Fire, below.

Ancient Beginnings

The Hearts On Fire story starts millions of years ago when diamonds began to form deep beneath the earth’s crust. Before the dinosaurs walked the earth, diamonds were growing and forming over millennia. 

Eventually, these special stones were pushed through volcanic pipes to the earth’s surface, where over time, they began to be mined. Only 5% of diamonds pulled from the earth are considered gem quality with the rest being utilised in drilling and machinery.

This small gem-worthy percentage is cut and polished before being distributed among retailers and wholesalers.

Modern Ideas

Glenn and Susan Rothman were diamond wholesalers with a wealth of experience, having begun their wholesale business in 1978. But it was in 1996, during a trip to Belgium, when the Hearts On Fire idea began to take hold.

There, they came across a round brilliant cut diamond displaying a hearts and arrows design due to its complex geometric cut. They were captured by the brilliance of this design and on their return to the US, they began to sell diamonds cut in a similar manner.

The Hearts On Fire name was born from that very first inspirational diamond and their first collection sold out soon after its release. This new wave of modern diamond cutting had captured the attention and the hearts of diamond lovers everywhere.

The Best of The Best 

Hearts On Fire ensures the quality of their stones by choosing only the most exceptional diamonds to become part of their collection. Each and every stone is individually and independently graded by the American Gemological Society, with less than 1% of all gem grade diamonds deemed fine enough to become a Hearts On Fire diamond.

To meet these exacting standards, stones must achieve:

• A grade of 0 or above for proportion of cut.
• A grade of 0 or above for polish.
• A grade of 0 for symmetrical cut.
• A range of D-I for colour (colourless and near colourless).
• A range of flawless to slightly included for clarity.

These high standards are achieved in part, by the extreme magnification (100X) used for inspection, shaping, and cutting of stones. Such an exacting selection and design process means all Hearts On Fire diamonds of 0.20 carat and above are described as ‘sensational’.

A Cut Above 

The exacting cut of a Hearts On Fire diamond is one of the key factors that sets it apart from the sparkling competition.

The cut of a diamond is one of the 4Cs that we use to evaluate and define diamonds (the other Cs are clarity, colour, and carat). The cut of a diamond can have a sizable impact on its final brilliance and fire, as well as its perceived value.

A well-cut diamond will refract the light more effectively, giving it that sought after dazzling sparkle.

What Hearts On Fire does so brilliantly is select the very finest diamonds and then apply a complex cutting process that reveals their true beauty. It’s this combination that makes their diamonds such a precious commodity.

First, they carefully analyse each rough stone, using the latest technology to realise its true potential. Then, highly skilled craftsmen cut the diamonds on vibration-free cutting wheels in the inimitable Hearts On Fire style.

This is an exceptionally skilled job, with less than 400 people in the world able to cut diamonds to this degree of precision. Once cut, the diamond displays a ring of eight hearts around the bottom, and a perfectly formed fire burst on top.

This unique design results in perfect symmetry and an increased surface area for the refraction of light. This creates a dazzling fire and brilliance, with the seven colours of the spectrum, that is unparalleled in other stones. This is a perfection you can see.

The Shape of Your Heart

A round brilliant Hearts on Fire diamond always has 58 facets, as opposed to machine cut diamonds that may have 57 or 58. It also takes four times longer to cut and polish a Hearts On Fire diamond due to the exacting precision required at each stage.

The round brilliant cut remains the most popular choice for Hearts on Fire diamonds, but they also have their own special square cut called the Dream.

The Dream has become a recognised cut in the industry, with 12 extra facets added to give the eye-catching square shape. With a light refraction rate of 93%, it is one of the most brilliant fancy shaped diamonds available anywhere.
