Deep, Oceanic Hue And Unparalleled Rarity Of Blue Diamonds
Coloured Diamonds
Boron is the primary element responsible for the blue colouration in diamonds. This element, similar in size to carbon, can easily be incorporated into the diamond lattice. Even trace amounts of boron can absorb red light, causing the diamond to exhibit a blue colour.
Interestingly, blue diamonds typically have very low levels of nitrogen. In addition to boron, a high concentration of hydrogen or the presence of nickel can also impart a blue colour to diamonds, indicating that not all blue diamonds are exclusively influenced by boron.
Natural blue diamonds, formed with their colour during the crystallization process, are exceedingly valuable. Modern techniques developed since the 1950s allow for the enhancement of diamonds, including the addition of colour. However, naturally occurring blue diamonds remain unparalleled in value, often fetching prices exceeding $100,000 per carat.
Blue diamonds are incredibly rare, making their discovery a significant event in the mining industry. The majority of natural blue diamonds are found in a few select locations around the world. Here are some of the legendary mines:
-
Argyle Mine, Australia:
This mine, owned by Rio Tinto, is famous for producing some of the world's most exquisite blue diamonds. -
Cullinan Mine, South Africa:
Managed by Petra Diamonds, this mine near Pretoria has yielded numerous notable blue diamonds. -
Golconda Mine, India:
Although less prolific, this historic mine has been a source of rare blue diamonds.
Blue diamonds are among the rarest of all diamonds, constituting only about 0.02% of the total diamonds mined. Their scarcity is a major factor contributing to their high value and desirability. When ranked on the rarity scale of coloured diamonds, blue diamonds are just behind red, violet, and purple diamonds, making them the second-rarest type.
This rarity ensures that blue diamonds command record-breaking prices at auctions and are considered highly praiseworthy among collectors and investors alike.
In the competitive world of diamond collecting, overtone plays a crucial role in determining the value of blue diamonds. Overtone refers to the secondary hues that are present alongside the primary colour of the diamond. These hues result from various impurities in the diamond.
A blue diamond with a higher saturation of its primary blue colour is highly valued, often selling for millions of dollars per carat. However, the presence of certain overtones can influence the price. Here are some of the examples:
- Gray Hue: This is more common and can decrease the value of a blue diamond.
- Violet Hue: Rare and desirable, increasing the diamond’s value significantly.
The interplay between the primary hue and the secondary overtones dictates the final price of the diamond, with rarer combinations fetching higher prices.
The Gemmological Institute of America (GIA) grades blue diamonds based on their colour intensity, which significantly affects their value. The intensity levels are Faint, Very Light, Fancy Light, Fancy, Fancy Intense, Fancy Vivid, Fancy Deep, and Fancy Dark. Due to the rarity of blue diamonds, those with intense and vivid colors are especially prized.
The presence of boron in the diamond’s structure is the primary factor influencing the depth of the blue colour. The deeper and more vivid the color, the rarer and more valuable the diamond becomes. Despite the wide tone range, the intensity of blue diamonds is generally lower compared to other fancy-coloured diamonds.
Blue diamonds stand out as some of the most exquisite and rare gemstones in the world. Their unique colour, caused by the presence of boron and other elements, coupled with their rarity, makes them highly sought after by collectors and enthusiasts.
From their limited geographical sources to their famous examples, blue diamonds symbolize unparalleled beauty and exclusivity in the world of gemstones. Whether admired for their stunning hues or their significant value, blue diamonds remain an enchanting affair.
