FAQs About Blue Diamonds
Is a blue diamond a real diamond?
Absolutely. Natural blue diamonds are 100% real diamonds that have formed over millions of years under the Earth’s surface, getting their blue color from trace amounts of boron within their crystal lattice. Because blue diamonds are so rare, some may be treated or synthetic, so make sure to shop with a reputable jeweler and get a certification from a gemological laboratory such as the Gemological Institute of America (GIA), to ensure their quality and authenticity.
Are blue diamonds more expensive?
The value of blue diamonds, like all diamonds, is determined by a variety of factors including color intensity and carat weight. Compared to traditional, colorless diamonds, as well as many other colored diamonds of similar quality, fancy blue diamonds will generally be more expensive thanks to their rarity.
How are blue diamonds graded?
Blue diamonds are graded based on the 4Cs: cut, color, clarity, and carat weight, with the most important value being color. They are categorized from faint blue all the way to fancy vivid blue, by the GIA (Gemological Institue of America), the more intense the diamond’s blue hue, the higher the grade and thus, the higher the diamond’s value.
How rare are blue diamonds?
Blue diamonds are among the rarest of all colored diamonds, accounting for only about 0.1% of all diamonds. Their distinctive blue hue is primarily due to trace amounts of boron within the diamond’s crystal lattice.
