OUR DIAMONDS

We hand select only high-quality, transparent, and knot-free natural diamond crystals. Diamonds that meet these rigorous standards are rare. So rare that only 1/10 of 1% of the world’s rough diamond crystals can become a Hearts On Fire diamond.

OUR CUT

A blend of art and science, the Hearts On Fire cut was designed to let in as much light as possible for an exceptional sparkle that’s impossible to miss. Our proprietary cutting formula 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.

OUR PROMISE

Our diamonds are guaranteed conflict-free, from point of origin to final piece. We travel to the ends of the earth to find the most beautiful diamonds on the market, and we source them responsibly and ethically from South Africa, Botswana, Namibia, Angola, Russia, and Canada. Our diamonds are 100% in compliance with the Kimberley Process.

The Elements Of Diamond Sparkle

When you buy a Hearts On Fire diamond, you’re buying the best. Learn more about what makes our sparkle so special.
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.
