The Story
The Passionate Heart is the name GIA gave this 1.01-carat natural red diamond. A dedicated Monograph bearing its name records the colour, cut and gemmological characteristics in detail.
Natural Fancy Red is already exceptionally rare. A weight exceeding one carat makes this diamond all the more remarkable. Its individual name and dedicated record give it a story to preserve and pass on.

Over one carat
Argyle Natural Red Diamond
A natural Fancy Red diamond from Australia’s Argyle mine. Red diamonds are rare even in very small sizes; this example weighs 1.01 carats, making it particularly noteworthy.
A heart-shaped cut calls for carefully judged contours and proportions. Curves, a central cleft and balanced sides are precisely fashioned to reveal the natural red across the facets.

A broader face-up appearance
The face-up measurements are 6.43 × 6.58 mm. According to the FCRF report, its face-up area is approximately 21.1% larger than the average heart-shaped diamond of the same weight.
That corresponds to the face-up dimensions of a heart-shaped diamond of approximately 1.21–1.23 carats, giving this 1.01-carat natural red diamond an especially generous outline.
