The Stories Behind the Biggest Jewelry Sales of 2015

 

top stories 2015

Now is the time to own (and sell) colored gemstones. Blue sapphires, striking red rubies, and pink diamonds made up 9 of the top 10 jewels sold at auction in 2015. Pink diamonds, in fact, accounted for a solid half of those sales. The only clear diamond to make it on the list? A 100-carat, emerald-cut stone that’s so large it looks unreal, the gemological equivalent of clown shoes. (Very, very expensive clown shoes.)

Of course, it’s one thing to be a massive colored stone; it’s another to have an equally sparkling provenance. Check out the backstories of this year’s top 10 jewelry sales, which combined for a grand total of $214 million, below.


JA applauds permanent extension of 15-Year Depreciation on Store Improvements

JAThe legislation is critical to jewelers

(NEW YORK) - Jewelers of America (JA), the national trade association for businesses serving the fine jewelry marketplace, welcomes the permanent extension of the 15-year depreciation on store improvements, which was passed by Congress on December 18 and is expected to be signed into law by President Barack Obama.

The important depreciation measure was part of a tax “extenders” package attached to sweeping tax extenders legislation. It marks a major victory for Jewelers of America, as the association has been fighting for more than a decade to make the depreciation provision permanent.

Workers threw away $5M in diamonds from Midtown jewelry

The mystery of how nearly $5 million in diamonds went missing from a Midtown jewelry store has been solved.

As it turns out, some dimwitted workers at J. Birnbach Inc. were helping their boss move to another floor and tossed three weathered wooden boxes filled with diamonds in a heap of trash without bothering to look inside, law enforcement sources said.

But a building security guard patrolling the third floor allegedly did take a peek — and discovered the mother lode: a cluster of expensive stones, including one worth $3.2 million.

Researchers Find New Phase of Carbon, Make Diamond at Room Temperature

Narayan

Researchers from North Carolina State University have discovered a new phase of solid carbon, called Q-carbon, which is distinct from the known phases of graphite and diamond. They have also developed a technique for using Q-carbon to make diamond-related structures at room temperature and at ambient atmospheric pressure in air.

Phases are distinct forms of the same material. Graphite is one of the solid phases of carbon; diamond is another.

“We’ve now created a third solid phase of carbon,” says Jay Narayan, the John C. Fan Distinguished Chair Professor of Materials Science and Engineering at NC State and lead author of three papers describing the work. “The only place it may be found in the natural world would be possibly in the core of some planets.”

Gold beads may boost cancer treatment

Scientists are investigating whether microscopic gold beads could make chemotherapy more effective, and reduce side effects for patients.

The above image, which is from laboratory research conducted by Dr Andrew Thorley, from the National Heart and Lung Institute at Imperial College London, shows gold nanoparticles (in red) being absorbed into human cancer cells (the centre – or nucleus – of each cell is in blue, and the endosome - part of the cell’s internal transport system - is green).

Researchers coat the gold nanoparticles in chemotherapy drugs, and target them to the tumour, explains Dr Thorley, whose team presented their latest work at a recent meeting of the British Thoracic Society...

Colombia possibly discovers world's largest sunken treasure

sunken treasure

CARTAGENA, Colombia – President Juan Manual Santos on Saturday hailed the discovery of a Spanish galleon that went down off the South American nation's coast more than 300 years ago with what may be the world's largest sunken treasure.

At a news conference in this colonial port city, Santos said the exact location of the galleon San Jose, and how it was discovered with the help of an international team of experts, was a state secret that he'd personally safeguard. The ship sank somewhere in the wide area off Colombia's Baru peninsula, south of Cartagena...

Rapaport reports polished diamond prices rise in November

Scarcities, holidays and Chinese demand supporting prices with 0.30ct. RAPI +3%

(NEW YORK) - Polished diamond prices firmed in November supported by shortages of select categories and seasonal holiday demand. Trading improved with dealers focused on filling U.S. holiday orders, but old challenges remain: Manufacturing is unprofitable at current rough price levels and the diamond distribution chain is overstocked, despite some scarcities. The RapNet Diamond Index (RAPI™) for 1-carat, GIA-graded diamonds rose 0.7 percent in November, its first increase in six months. RAPI for 0.30-carat diamonds advanced 3.3 percent and RAPI for 0.50-carat diamonds grew 1.1 percent. RAPI for 3-carat diamonds fell 0.6 percent. RAPI for 1-carat diamonds remains down 7.1 percent since the beginning of the year.
