Hearts On Fire Diamond Sourcing

OUR DIAMONDS

  • Sourcing
    Sourcing

    We hand select the most beautiful diamonds on earth, choosing only rough diamond crystals that are internally clear and knot-free. By using only the most exceptional rough diamond crystals, our cut and polished gemstones have a clean, brilliant, and unmistakable sparkle in their finished form.

  • Light Return
    CONSISTENT CUT

    Cut is everything when it comes to a diamond’s sparkle, beauty, and overall value. Our cutting process is a blend of art and science, perfected over many decades by our master diamond cutters. Our cut highlights a diamond’s physical properties—like the way it reflects and refracts light—and emphasizes its inherent beauty with precise angles that show it off to its most magnificent effect.

  • Rough Diamonds
    SIGNATURE PATTERN

    Every single one of our diamonds, even our tiniest accent diamonds, has our signature Hearts & Fireburst pattern. This pattern is a result of our cut, and a testament to its consistency. It is our promise that every diamond in a piece of Hearts On Fire jewelry will sparkle with our signature brilliance.

Our Signature Diamond Cut

  • CRAFTSMANSHIP

    There are two components to a diamond’s cut. One is shape: at Hearts On Fire, we cut diamonds in round and square shapes, as these two forms best amplify a diamond’s beauty.

     

    The second component is the precision of the cut within those two shapes. We spent years developing a precise formula for our diamond cut, one that takes symmetry, proportion, and a diamond's individual shape into account.

     

    Hearts On Fire master diamond cutters apprentice for between 5 and 10 years before they can cut a 1+ carat diamond, and when they do, our process is so rigorous and exacting that it takes 4 times as long to cut a Hearts On Fire diamond than it would take to cut a generic diamond.

  • PROCESS

    Every diamond starts as a rough crystal—that’s its natural form. We take the purest rough crystals and begin the cutting process using a value scan program that allows us to locate any imperfections and inclusions on our rough diamond crystals. This way, we can cut the diamonds to show their best effect and eliminate any imperfections when possible. Using data from this scanner, we divide the diamonds with a diamond saw, so they can then be cut into two individual gems. 

     

    Next, to produce a round shape, we gridle the diamonds by placing two diamonds side-by-side on axles spinning in opposite directions. The friction between the square octahedral diamond crystals and the crystal on the opposing spindle rounds them out perfectly, readying them to be cut and polished.

     

    We then use vibration-free cutting wheels to cut and polish our diamonds for ideal proportions and symmetry. We polish them at 100X magnification, which is 10 times the industry standard.

  • Our Technology

    Our secret to serious sparkle? Aside from choosing the finest raw crystals and employing the best craftspeople, we also use state-of-the-art technology and tools.

     

    We have upgraded from the traditional loupes that were the mainstays of diamond cutters for centuries, and now use them in tandem with high-definition cameras, high-resolution, large-format monitors with on-screen cutting templates, and laser measuring devices. These tools are what let us cut and inspect our diamonds at 100x power magnification.

     

    We also use completely vibration-free cutting wheels, aviation-quality bearings, and leveled motors. By placing controls on these components of our cutting process, there’s less room for error and more possibility for perfection and sparkle. We also disassemble and re-calibrate our cutting tools each month, ensuring that our equipment can deliver the best performance and highest degree of consistency in the hands of our highly skilled craftspeople.

     

    We are at the forefront of technological advancement when it comes to diamond cutting, and we are pioneering new techniques all the time.

The Elements Of Diamond Sparkle

  • Brilliance

    The first measure of a diamond’s sparkle is brilliance, or how well it reflects white light. When you see a diamond sparkling in a dimly lit or candlelit room, what you’re seeing is its brilliance. If a diamond isn’t cut correctly, it will appear dim and dull, even in perfect lighting.

  • Fire

    The second measure of a diamond’s sparkle is fire, or how well it displays colored light. When you see a diamond with a rainbow-like appearance, it's a result of the correct balance of proportions from the top and bottom of the diamond. Diamonds with too deep or too shallow a cut won't refract colored light properly, resulting in a flat appearance.

  • Scintillation & POLISH

    The last measure of a diamond’s sparkle is scintillation, or how well the diamond reflects light when it's moving, when the light source is moving, or when the person wearing the diamond is moving. When a diamond has high scintillation, it has very few spots where no sparkle occurs. In a well-cut diamond, most of the surface area of the diamond emits some visible sparkle. 

     

    Finally, polish affects the ability of a diamond to absorb, refract, and reflect light. The more polished and transparent the diamond, the more sparkle it will have. We polish our diamonds at 100X magnification, 10 times the industry standard, so they’re as beautiful and bright as possible.
