Hong Kong luxury jeweler Chow Tai Fook unveiled an incredible necklace designed from the twinkling progeny of the 507.55-carat Cullinan Heritage rough diamond.

The massive diamond, which was purchased by the jeweler in 2010 for $35.3 million, yielded 24 D-flawless gems, including the necklace’s focal point, a perfect 104-carat round brilliant. The museum-quality piece is dubbed “A Heritage in Bloom.”

Chow Tai Fook enlisted the talents of jewelry artist Wallace Chan to assemble the family of “Heritage” diamonds, and a supporting cast of 11,500 addition precious gemstones, into a work of art that is estimated to be worth at least $200 million.

The diamond total weight of the piece is 383.4 carats.

Violet Diamonds

Pure violet diamonds without modifying colors are impossibly rare, perhaps even rarer than purple diamonds. The presence of the trace element hydrogen in the atomic lattice is responsible for violet diamonds while purple diamonds are caused by plastic deformation. Violet diamonds and purple diamonds are two separate colors. Some use the words “violet” and “purple” interchangeably. Violet diamonds are a distinct color group. Violet diamonds will appear more blue-grey to the eye while purple diamonds appear red or pinkish.
Fancy violet diamonds are assessed according to intensity of color, or a combination of saturation and tone. The more intense a diamond’s color saturation, the more it will be worth.

They are graded as follows: Fancy Violet, Fancy Intense Violet, Fancy Deep Violet and Fancy Dark Violet.
Violet diamonds of any kind are typically small and very rarely exceed one carat.
Natural fancy violet diamonds are extremely valuable. More valuable still are those that are a pure violet color without any secondary modifying color. Modifying colors tend to devalue violet diamonds, but they are still exceptionally rare and will always be highly valued.

The Argyle Violet
The Argyle Violet, a 2.83 oval shaped violet diamond, was the dazzling centerpiece of the 2016 Argyle Pink Diamonds Tender. It is the largest violet diamond ever recovered from the Argyle mine.

Just 12 carats of polished violet diamonds have come from the Argyle mine over 32 years of mining.

The rough gem originally weighed 9.17 carats.

Gemstones of Pailin, Cambodia

The southeastern corner of central Thailand along the Cambodian border has been an important source of fine ruby and sapphire for centuries. Pailin is at the edge of the Cardamom Mountains in the west of Cambodia, 25km from the border of Thailand. Pailin was a prosperous town due to its gem deposits. Those resources attracted the attention of the Khmer Rouge.
Sapphire mining near Pailin using high-pressure water to turn the gem rich gravels into mud. The mud is then processed.
The Khmer Rouge were Cambodian Communists who mounted an insurgency against the national government in 1967 and succeeded in taking power in 1975 under their notorious leader Pol Pot.

They ruled for 4 years until they were ousted by the Vietnamese army in 1979.

The Khmer Rouge regime was distinguished by the genocide of an estimated 1.5 million people.
The rare blue sapphire of the Pailin area are very highly regarded. They range in colour from light to deep blue, but with a distinctive purity and intensity of color. The Khmer Rouge used proceeds from mining Pailin sapphire to fund their offensive and later their government once they gained national power.

Pailin sapphire was one of the first "blood gemstones."
The first stones ever to be treated with heat to improve their colours allegedly originated from the Pailin mines in Cambodia. Cambodia is famous for commercializing gem treatment.
The precious stone industry in Pailin today is dwindling with deposits largely depleted. Cambodia's gem supplies are declining sharply.

Sapphire mining was not the only type of digging that was carried on in Pailin. It is considered one of the most heavily landmined areas in the world.
