NATURAL FANCY BLUE COLORED DIAMONDS
Colored diamonds — also known as “fancy diamonds” — are an extraordinary and rare category of natural diamonds found in a stunning array of hues. In the world of diamonds, rarity heavily influences value, and fancy colored diamonds are much less common than traditional white diamonds.
Only about one in every 10,000 diamonds naturally forms with a fancy color, making them some of the most coveted and valuable gemstones available. These diamonds occur in shades ranging from popular pinks and yellows to ultra-rare blues, greens, oranges, and reds.
Unlike colorless diamonds — which are graded based on their absence of color using the GIA’s D-to-Z scale — fancy colored diamonds become more valuable as the richness and saturation of their color increases. These diamonds fall outside the Z scale, and the most vivid examples are exceptionally rare.
There are 12 primary color categories, more than 90 secondary hues, nine intensity levels, and over 230 possible color combinations. Blue diamonds often feature modifiers like gray or green, but those with pure, vivid coloring are the most highly prized.
Natural fancy blue diamonds are among the rarest of all fancy colors. Their exceptional beauty and scarcity are due to the presence of boron — a trace element that causes the blue hue. The world-famous “Hope Diamond,” a deep blue 45.52-carat gem, is a prime example of this fascinating category.
BLUE DIAMONDS
Fancy blue diamonds are among the most captivating gemstones in the world. Their alluring blue tones come from trace amounts of boron in the crystal structure, which absorbs yellow light and gives the stone its signature blue color.
Blue diamonds can range in shade from soft baby blue to vibrant teal to deep, rich navy. While most stones contain slight gray or green undertones, pure blue diamonds with even saturation and minimal inclusions are exceptionally rare and valuable.
Their breathtaking appearance, paired with their limited availability, has made fancy blue diamonds a symbol of sophistication and prestige. Whether featured in an heirloom pendant or a unique engagement ring, they stand out as luxurious and meaningful centerpieces.
GRADING NATURAL FANCY COLORED DIAMONDS
Grading fancy colored diamonds requires expertise, as color characteristics vary widely. The Gemological Institute of America (GIA) leads the industry in color diamond grading, using side-by-side comparisons and reference stones to assess hue, tone, and saturation.
Unlike white diamonds — graded for lack of color — fancy diamonds are graded for the presence and intensity of color. The GIA’s scale includes levels from Faint and Very Light to Fancy Intense and Fancy Vivid, with the deepest saturations being the most valuable.
At Rêve Diamonds, we sell only 100% natural blue diamonds that have not been color treated. Every stone is independently graded and comes with a GIA certificate confirming its natural origin and authentic color characteristics.
