The auction house says the jewel, nicknamed "blue perfection", is the biggest diamond of its kind ever to appear at auction.
The world's largest flawless fancy vivid blue diamond is expected to fetch up to £15m when it goes on sale at Christie's next month.
Christie's New York has proudly displayed 'The Blue', the magnificent 13.22 carat diamond which will headline the upcoming sale in Geneva.
Experts predict it will fetch an eyebrow-raising sale price of between $21m (£12.5m) and $25m (£15m).
Rahul Kadakia, Head of Jewellery for Christie’s Americas & Switzerland, said: "To have a stone that weighs 13 carats is near impossible.
"The stone is internally and externally bereft of any imperfections... in simple terms, it's the best blue diamond in the world."
Blue diamonds are extremely rare and make up less than two per cent of the world's diamond production.
Like most blue diamonds, 'The Blue' is thought to have been mined in South Africa.
Christie's would not reveal the owner of the jewel, but said it had been in the owner's possession for a long time.
The auction house said the owner approached them after seeing several coloured diamonds fetch record prices in recent sales.In November Sotheby's auction house sold a plum-sized diamond, known as the Pink Star, for a record £51.7m.
A month earlier Sotheby's sold a "flawless" white diamond for a record £19m.
'The Blue' will be auctioned at the Geneva Magnificent Jewels Sale on May 14 alongside the 'The Ocean Dream' diamond.
According to Christie's 'The Ocean Dream' is the largest fancy vivid blue-green diamond in the world. At 5.5 carat, it is expected to fetch between £4.5m and £6m.
Also on sale is the exotic 'The Rajah' diamond, which is thought to have purchased from India by Tiffany & Co in the 19th Century. It is estimated to sell for between £1.8m and £3m.
Christie's has said it hopes the sale will raise in excess of £60m.
Step into the mesmerizing world of natural Pink diamonds, synonymous of elegance and sophistication. These exquisite gems have stolen the spotlight in the realm of fine jewelry, captivating the hearts of fashion enthusiasts around the globe.
In this article, we’ll explore the enchanting features of Fancy Pink diamonds, uncovering their origins, possible tones, and the growing fascination around them. As we delve into their unique characteristics, you’ll learn how they compare to other popular pink gemstones, revealing the distinct advantages that set them apart.
The Origin Of Their Mesmerising Hues
Fancy Pink diamonds are the result of a remarkable geological process that lasted millions of years. During their formation process, atomic traces of minerals such as hydrogen, nitrogen, or boron were introduced into their crystalline structure, resulting in impressive hues.
However, another scientific theory states that the pink hue comes from a deformation in the crystal lattice of the stone, a phenomenon caused by extreme pressure.
Whichever the cause, thanks to our Earth’s natural transformations, today we get to enjoy the exceptional shades of Pink diamonds.
From delicate pastel tones reminiscent of blooming cherry blossoms to intense, vivid shades that command attention, natural Pink diamonds offer a diverse palette of hues that ignite the imagination.
Rarity And A Growing Fascination
The allure of these unique stones lies not only in their enchanting beauty but also in their rarity.
As luxury enthusiasts and jewelry connoisseurs seek to come in possession of the most exclusive and coveted pieces, the interest surrounding fancy pink diamonds continues to grow. With the recent closure of the renowned Argyle mine in Australia, a significant source of Pink diamonds, their scarcity has skyrocketed.
Pink Diamond’s Unparalleled Properties
The refractive index of a diamond is approximately 2.42. This high refractive index is one of the factors that contribute to the exceptional brilliance and sparkle that diamonds are renowned for. The high refractive index allows diamonds to bend and reflect light in a way that creates maximum dispersion and brilliance, resulting in their captivating play of light and fire. It is this unique optical property that sets diamonds apart from other gemstones and contributes to their timeless allure and desirability.
Diamonds are renowned for their exceptional hardness, ranking 10 on the Mohs scale, which is the highest possible rating. This remarkable property makes diamonds highly resistant to scratching and abrasion, ensuring their longevity and durability even with daily wear.
The hardness of a diamond contributes significantly to its value. Diamonds are prized for their ability to withstand the rigors of everyday use without losing their beauty or succumbing to damage. This durability ensures that diamond jewelry, such as engagement rings and heavily worn pieces, can be cherished forever and passed down through generations.
What About Other Pink Gemstones?
This pink gemstone is often used in jewelry for its vibrant color. Pink tourmaline can be found in various parts of the world, including Brazil, Afghanistan, Mozambique, and the United States. Each location may produce unique variations in color and quality, making it more complicated for the regular customer to understand how to measure and compare characteristics.
Tourmaline ranks 7 to 7.5 on the Mohs' scale of hardness, making it moderately durable, but relatively softer compared to Pink diamonds. With a refractive index between 1.624 and 1.644, pink tourmaline exhibits a good amount of brilliance and light dispersion.
This mineral showcases a soft, delicate pink hue that does not typically offer much sparkle. There are multiple levels of transparency available, from very translucent to milky opaque or smoky with yellow or brown undertones.
Scoring a 7 on the Mohs scale, pink quartz is relatively durable and suitable for some types of jewelry. However, it is still important to protect it from impact, and best suitable for earrings and low-wear pieces.
The intensity of its color depends on the place of origin and the combination of trace elements present within its crystal structure.
With a hardness of 9 on the Mohs scale, pink sapphires are very durable and resistant, making them suitable for all kinds of jewelry pieces. However, they are more prone to scratches than diamonds.
Kunzite is quite affordable because it’s relatively unknown although it can be found in many places like Afghanistan, Brazil, Madagascar, and the USA.
Like most color stones, kunzite can be undergo irradiation or heat treatments to enhance its color. Exposure to heat and bright light can cause color in both natural and treated kunzite to fade over time.
Most morganite deposits are found in Brazil, but the highest quality specimens come from Madagascar. Typically, morganite enjoys a high transparency with minimal inclusions resulting in clear, polished stones.
Scoring a 7.5 to 8 on the Mohs scale, Morganite is safe and durable enough for jewelry.
Your Best Choice: Pink Diamonds
There are multiple options to choose from to create a jewel with pink gemstones. However, they all fall short when compared to the durability and brilliance of natural Pink diamonds. With sources becoming more scarce while demand continues grows, Pink diamonds keep appreciating in value making them a better financial choice when compared to other gemstones which tend to loose value in the resale marker. Pink diamonds present multiple advantages for their investment potential and as a valuable asset to be passed on for generations.
When purchasing color gemstones, it’s important the buyer requests a professional laboratory report that discloses any enhancements to make an informed decision. Unfortunately for most consumers, it’s hard to find full-detailed information on a finished jewelry piece and it requires additional effort and inquiries to confirm the quality of a gemstone.
