In terms of color, excavated natural diamonds come in two groups. The first one is called Colorless: transparent diamonds, which can only have a light hue of yellow. They are the most common and easily recognized by the 4Cs color gradation. The other color group is called Colorful or Fancy diamonds. These are rare minerals with their own color, examination, and pricing. 4Cs don't suit Fancy diamonds much. But how are they created?
To answer this question accurately, let us slightly dive into chemistry. A rough diamond as an item is a group of carbon molecules united under enormous pressure. Usually, diamond is known as a single-element material: 99.95% of it is carbon. As we can see, there is still 0.05% left unmentioned. Nature abhors a vacuum: other chemical elements can sneak inside a diamond while it's been processed. These "intruders" affect the color of a gemstone and create a Fancy diamond.
The stage of affection depends on how many minerals joined the carbon mass and how significant their parts are. For instance, if Boron takes the majority of the empty room, a diamond will have a deep, saturated color of blue. E voila, a Fancy blue diamond is naturally born.
Aside from the classic carat, cut and clarity examination, blue diamonds also have their intense color gradation:
Prices increase as the color saturation does. It concerns all the fancy diamonds: deeper color means higher cost. Unlike with the "white" diamonds, where the cut and clarity are the most important, and here priorities settled on color and carat weight.
There is also a "little brother" of a blue diamond – blue sapphire. It usually has a brighter blue color. There are several ways to recognize it without professional help:
Blue diamonds are rare stones, which are most of the time found below a 1 carat weight. Suddenly, in 2014 blue diamonds made a lot of noise. "The Zoe Diamond," as an example, vivid blue pear-shaped 9.75 carat stone, broke the world record as the most expensive jewel sold at auctions that year. The blue diamond found a new owner for $32,6 million!
A year after the record was broken again by another blue diamond – "The Blue Moon," 12 carat vivid blue diamond. Sotheby's successfully sold the fancy diamond for a tremendous price – $48.4 million.
Another blue diamond of high price was found this October 2019! Cullinan mine "gave birth" to 20.08 carat blue rough diamond. Experts evaluate its approximate unprocessed cost under $15 million. Depending on what form jewelers will decide to cut this blue diamond into, its real price can rise twice, at least. It seems "Zoe" and "The Blue Moon" will face some exceptional blue competition.
As part of Fancy diamonds, blue diamonds are rare indeed. The question will be, "are blue diamonds considered rare among colored minerals?".
Among pink and red diamonds, blue stones are in the top-3 of the least present diamonds on the market. Limited supply accumulates great demand for blue stones. The majority of blue diamonds come from only two mines on the planet: Argyle in Australia, and Cullinan in SAR. The first one is going to close in 2020, reducing the excavation potential of blue diamonds twice. It is fair to expect blue diamonds prices will rise dramatically. Blue diamonds nowadays might appear as an attractive investment.
