We polish our diamonds at 100X magnification for a precise and consistent cut that allows them to sparkle to their fullest potential with maximum light return.

Hearts On Fire selects optically pure rough crystal which ensures that the maximum amount of light captured, scintillated, and reflected is always at its most brilliant.  Less than 1% of the world’s rough diamond crystals meet our baseline standards for transparency, clarity, and color.

Each Hearts On Fire diamond is responsibly sourced from point of origin to gem cut and in compliance with the Kimberley Process.

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.

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.

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.
