A young girl in the Democratic Republic of Congo found the egg-sized yellow diamond in a pile of mining rubble.
For someone with $55 million to spare on an egg-sized diamond, the world's most expensive necklace is on sale this month at a jewelery show in Singapore, reflecting Asia's growing appetite for precious gems and expensive baubles.
Known as L'Incomparable, the necklace created by luxury jeweler Mouawad features a yellow, internally flawless diamond of more than 407 carats suspended from a rose gold setting that is studded with 90 white diamonds weighing nearly 230 carats.
"Serious interest" has been expressed by a couple of potential buyers from Asia, said Jean Nasr, managing director of Mouawad in Singapore, declining to identify their nationalities.
"People who will get something like this are looking at it from a different perspective because this is definitely an investment piece," he told Reuters.
The necklace’s 637-carat centerpiece stone is world's largest internally flawless diamond.
The necklace, whose centrepiece diamond was found by chance in a pile of mining rubble by a young girl in the Democratic Republic of Congo about 30 years ago, will be the flashiest item on offer at the Singapore JewelFest on October 11-20.
But there will be plenty of other glitz from American, European and Asian designers worth another $200 million or so.
Singapore, a tiny Southeast Asian nation with the world's highest concentration of millionaires, has positioned itself as a destination for the ultra-rich with a busy wealth management industry, luxury properties, top hotels, gourmet restaurants, high-end boutiques and two casinos.
The stunning necklace, which is on sale at a jewelry show in Singapore, reflects Asia's growing appetite for precious gems and expensive baubles.
While the city-state boasts a very low crime rate, security will be extremely tight with so much jewelery on display at a pavilion outside an upscale mall.
It seems unlikely there would be a robbery in Singapore like the daylight heist of about $136 million worth of jewelery on show at a hotel in the French Riviera resort of Cannes in July.
But Filippo Melchionni, in charge of guarding L'Incomparable and the rest of the jewellery on show, is taking no chances.
Managing Director of Mouawad Boutique, Jean Nasr, holds the 637-carat necklace at a media event in Singapore.
Security includes armed guards, plainclothes supervisors, cameras, motion detectors and bullet-proof display cases but the most critical time is when the pieces are shown to customers.
"This is the moment that the stones are under risk because they can be passed hand-by-hand, they can be exchanged," said Melchionni, chief operating officer for Asia-Pacific at the Ferrari Group, an Italian logistics company for luxury goods.
"Every night it is going back to our vault. We have an armored truck to move the stones."
L'Incomparable, completed in 2012 and certified as the priciest necklace in existence by Guinness World Records earlier this year, is an extravagant novelty.
But Asia, especially China, has become an important and resilient growth area for sellers of pricey jewellery, cars, boats, wine, artwork and other lavish items.
Australian miner Rio Tinto Ltd, which showed off its finest coloured diamonds in Hong Kong last month, believes the United States will remain its key market for diamonds but sees China growing fast.
Demand for diamonds in China, now the world's second-largest market after the United States, helped boost global sales at Tiffany & Co in the latest quarter, leading the U.S. jeweller to raise its annual profit forecast.
The show in Singapore, now in its 11th year, expects some Chinese buyers but many locals and visitors from Indonesia, Malaysia, Thailand, Vietnam, Cambodia and Russia will also be there, said Kean Ng, chairman of the Singapore JewelFest.
"You have the high-end customers but of course you have the browsers coming in and they usually end up buying something that's within their budget," he said.

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

Brilliance
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.

Hardness
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?
Tourmaline
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.
Pink quartz
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.
Pink Sapphire
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
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.
Morganite
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.
