The Perfect Palette of spring colors is comprised of three stunning diamonds: a Fancy Vivid Blue diamond of 2.13 carats, a Fancy Vivid Purplish Pink diamond of 2.17 carats and a Fancy Vivid Orange diamond of 2.34 carats. Each of these gemstones’ vibrant and richly saturated color is a wonder of nature. Only one in ten-thousand diamonds graded by the Gemological Institute of America is awarded the status of a fancy color, the highly regarded “vivid” saturation in color sets these diamonds in an entirely different class. These three stones, all formed by entirely different forces of nature, constitute a diamond collector’s dream.
Natural blue diamonds are among the rarest of colored diamonds and their color comes from the presence of minute amounts of the element boron incorporated within the lattice structure of the stone during its crystallization process. The necessary amount of boron is so minuscule, less than one boron atom per one-million of carbon atoms can give a diamond a blue color. The absorption of boron occurs approximately one-hundred-million years prior to the rough material being mined.
Pink diamonds, caused by an anomaly in the crystal lattice of the stone, have always been considered extremely rare. Historically found in India in the famous Golconda mines, pink diamonds typically display a faint pink pale hue with a chemically low nitrogen content. The 17th century gemstone trader, Jean Baptiste Tavernier, referred to pink diamonds as ‘rose’ colored. In the 1980s, a pink diamond source was discovered in Australia. Called the Argyle Mine, for a nearby lake, pink diamonds of small sizes were regularly mined for the first time in history. Since late 2020, the world’s preeminent source of pink diamonds is now closed.
Pure orange diamonds, not modified by any other color, are also referred to as 'fire diamonds' by famous gemologist Edwin Streeter in his book The Great Diamonds of the World. So few purely orange diamonds have been graded that the origin of their color still bears a mystery. According to the GIA, it is unusual for orange diamonds to reach such high levels of saturation to be deemed ‘Fancy Vivid’.
Colored diamonds of all hues are very difficult to cut from their rough form. If not calculated correctly, the color could be lost or disappear completely. The stone must be cut to maximize the color, yield the largest size and retain the stunning brilliance diamonds are famous for. The Perfect Palette displays both the wonders of nature and the skill of highly talented diamond cutters.
