Pink Diamond Nets $20M at Sotheby’s

A pink diamond ring was the top lot at Sotheby’s Hong Kong auction this week, garnering HKD 155.8 million ($19.9 million), or $1.9 million per carat.

The cut-cornered rectangular mixed-cut, 10.64-carat, fancy-vivid-purplish-pink, internally flawless stone, set between two white trapeze diamonds, had a presale estimate of HKD 150 million to HKD 200 million ($19.1 million to 25.5 million). Total proceeds at the Magnificent Jewels and Jadeite auction came to HKD 300.8 million ($38.3 million).

A 100.02-carat, fancy-intense-yellow diamond necklace by Anna Hu, fashioned in the shape of a pipa — a Chinese musical instrument similar to a four-stringed lute — sold for HKD 45.3 million ($5.8 million) against a presale estimate of HKD 40 million to HKD 50 million ($5.1 million to $6.4 million). The necklace was one of five pieces in Hu’s Silk Road Music Collection, all of which found buyers, Sotheby’s told Rapaport News.

Meanwhile, a necklace featuring a pear-shaped, 15.08-carat diamond suspended from a row of alternating step-cut and brilliant-cut diamonds brought in HKD 9.2 million ($1.2 million). It was estimated at HKD 7.6 million to HKD 10 million ($968,860 to $1.3 million).

Three of the auction’s top lots failed to find a buyer, including an emerald-cut, 80.88-carat, D-flawless, type IIa diamond with a presale estimate of $10 million to $12.8 million, Sotheby’s added. An 11.88-carat, pigeon’s blood Burmese ruby and diamond ring by designer Raymond Yard, valued at $5.6 million to $8.2 million, and a jadeite bead necklace with a diamond clasp, estimated at $3.2 million to $4.1 million, also went unsold.

Alrosa finds Matryoshka-style stone, the first in diamond mining history

An unusual diamond with another diamond found inside was mined in Yakutia at the Nyurba mining and processing division of Alrosa, the Russian miner announced Friday.

Due to its peculiarity, the stone resembles a traditional Russian Matryoshka doll. According to the experts who have studied the find, this is the first such diamond in the history of global diamond mining, Alrosa said.

According to scientists, the diamond may be over 800 million years old. Despite its complex structure, it weighs only 0.62 carats.

Specialists of the Yakutsk Diamond Trade Enterprise discovered this unusual diamond during a sorting process and handed it over to the Research and Development Geological Enterprise of Alrosa.

There, it was studied using several methods, including Raman and infrared spectroscopies, as well as X-ray microtomography. Based on the results of the study, the scientists have a theory about how the crystal was formed; that there was an internal diamond at first, and the external one was formed during the subsequent stages of growth.

“The most interesting thing for us was to find out how the air space between the inner and outer diamonds was formed. We have two main hypotheses,” said Oleg Kovalchuk, deputy director, innovations at ALROSA’s Research and Development Geological Enterprise.

“According to the first version, a mantle mineral captured a diamond during its growth, and later it was dissolved in the Earth’s surface. According to the second version, a layer of porous polycrystalline diamond substance was formed inside the diamond because of ultra-fast growth, and more aggressive mantle processes subsequently dissolved it.

Due to the presence of the dissolved zone, one diamond began to move freely inside another on the principle of matryoshka nesting doll,” said Kovalchuk.

“As far as we know, there were no such diamonds in the history of global diamond mining yet.”

Petra to Hold Special Tender for 20.08-Carat Blue Diamond

Petra Diamonds will hold a special tender of the 20.08-carat blue diamond. The stone, a gem-quality Type llb diamond, was recovered from the Cullinan mine in South Africa last month.

Viewings will take place at Petra’s diamond marketing offices in Johannesburg from November 1-7 and at the Diamond and Exchange and Export Center from November 8-15.

South Africa’s Petra Diamonds could make up to $15 million for a 20.08 carat blue rough diamond it recovered in September at its iconic Cullinan mine, when it goes for sale at a planned tender in Johannesburg next month.

Investment bank Berenberg valued the “exceptional” blue gem quality diamond at between $10 and $15 million, based on prices Petra has achieved for similar roughs from Cullinan in previous years. In 2015, the miner sold “The Blue Moon of Josephine”, a 29.6 carat blue stone, for $48.5 million, marking a world record price per carat at auction for any diamond at the time.

Hong Kong Retail Falls to Record Low

Sales of jewelry and other luxury items in Hong Kong sank in August, marking the sharpest monthly decline on record as protests in the municipality hit tourism and consumption.

Revenue from jewelry, watches, clocks and other valuable gifts dropped 47% year on year to HKD 3.93 billion ($501.3 million) during the month, the municipality’s Census and Statistics Department reported Wednesday. That marks the lowest monthly decline for jewelry since the department began publishing results in 2005, according to a public data archive. Sales across all retail categories slipped 23% to HKD 29.36 billion ($3.74 billion).

Demonstrations against an extradition bill have been escalating since June, forcing luxury stores, train stations and the city’s airport to shut down. Although the bill has been scrapped, unrest has continued, with police reportedly shooting an 18-year-old protester Tuesday, and more than 100 people, including 30 police officers, being hospitalized amid the increased violence.

The situation has led to a sharp decline in travelers from China and abroad, as well as weakened local purchasing. The number of tourists visiting Hong Kong was down 39% to 3.6 million in August, the Hong Kong Tourism Board reported. Of those, 2.8 million came from mainland China, a decline of 42% over the same period last year.

The overall retail decline was “even worse than that recorded in September 1998 during the Asian financial crisis,” a government spokesperson noted. “Apart from the weak consumer sentiment amid subdued economic conditions, the plunge in August mainly reflected the severe disruptions to inbound tourism and consumption-related activities caused by the local social incidents.”

The government expects weakness in the market to continue as conditions persist, it explained.

“Retail sales will likely remain in the doldrums in the near term, as the worsened economic outlook and local protests involving violence continue to weigh on consumer sentiment and inbound tourism,” the spokesperson added.

Swiss bank UBS also expects a continued decline in the market, noting a more challenging outlook for hard luxury, which includes jewelry and watches, versus soft luxury, comprising bags, leather and clothing.

“This is particularly prevalent in the Chinese market, with hard luxury more exposed to recent [yuan] depreciation and protests in Hong Kong,” the bank explained. “Because of their long-term availability and high price tag, these are less likely to benefit from repatriation of demand in case of short-term disruptions in Hong Kong. Note that 50% of Chinese diamond jewelry was purchased in Hong Kong in 2018, [so] the near-term disruptions to sales [are] likely to be significant.”

In the first eight months of the year, retail sales of jewelry, watches, clocks and other valuable gifts decreased 14% to HKD 50.06 billion ($6.38 billion). Sales in all retail categories for the January-to-July period fell 6% to HKD 305.05 billion ($38.9 billion).
