A Possible Record-Breaking Diamond Headlines Upcoming Auction

Christie’s Geneva Magnificent Jewels auction is set for Tuesday, November 10 and the headliner is a stamp-sized pink diamond that could set a new record.   Here’s a look at that and four other stunners set to go under the hammer on that day.

1.  An Important Coloured Diamond Ring


We wrote extensively about this stone in September.   It is a 16.08-carat Fancy Vivid pink diamond, the largest Fancy Vivid Pink ever sold at auction.  The pre-auction estimate for the diamond has been set for between $23 and $28 million (USD).   If it ends up selling for more than $33,768,000, it will break the record for the highest per-carat price for a pink diamond in history.

2.  An Important Coloured Diamond Pendant


A massive 91.81-carat Fancy Vivid yellow cushion-shaped diamond features a pavé-set diamond loop at the top and is mounted in gold.   The pendant is expected to sell for between $3.9 and $4.9 million, an estimate that might be a little low considering the size of the stone.

3.  An Important Coloured Diamond Ring


The centerpiece of this ring is a 21.52-carat Fancy brown-pink pear brilliant-cut diamond and includes baguette-cut diamond shoulders.   The estimates for this ring have been set at between $1.5 and $1.9 million.

4.  A Rare Coloured Diamond Ring


The only blue diamond on our list, this is a Fancy dark bluish gray cushion-shaped diamond weighing in at 25.00 carats.   Driven by the rarity of the stone’s colour, the pre-auction estimate has been set for between $1.2 and $1.5 million.

5.  A Coloured Diamond and Diamond Ring


The final item on our list, a 9.28 carat Fancy Vivid yellow oval brilliant-cut diamond flanked by triangular-cut white diamond shoulders.

4.  A Colored Diamond and Diamond Ring


This amazing ring features a main stone that is a pear-shaped modified brilliant-cut Fancy Intense yellowish green diamond.   The diamond, which weighs in at 7.11 carats also features a circular-cut pink diamond surround.   The estimate for the ring is between $250,000 and $350,000.

A 75-Carat Yellow Diamond Set To Shine This Month


A massive, stunning yellow diamond ring will be headlining Christie’s Important Jewels auction coming up on October 20.

The cushion modified brilliant-cut Fancy Vivid yellow diamond, weighs in at 75.56 carats and is expected to sell for between $3 and $4 million.   That amount breaks down to between $40,000 and $53,000 per carat.

The current record for yellow diamonds is held by the 100.09-carat Graff Vivid Yellow which sold last year for $16.3 million or $162,853 per carat.

Other diamonds set to go under the hammer at the October 20 sale include a 34.12-carat cushion-cut Fancy Yellow diamond mounted on platinum and a diamond pendant featuring a 36.23-carat Fancy Brownish Yellow diamond.

A “Stamp Sized” Pink Diamond Could Set A Record


The largest diamond of its kind is set to go to auction later this year and the sales price could be as high as $28 million.

The 16.08-carat diamond will be the highlight of Christie’s Magnificent Jewels auction in Geneva coming up on November 10.

The Fancy Vivid Pink diamond is described as “stamp-sized” and is the largest Fancy Vivid Pink diamond ever sold at auction.

“The fancy vivid pink grading means the hue is of the purest and strongest saturation,” said Rahul Kadakia, Christie’s head of jewelry.

“The color is even and shows no trace of a secondary color that may include purple, orange brown or grey in pink diamonds of a lower grade.”

The pre-auction estimate for the diamond has been set for between $23 and $28 million (USD).   The current per-carat record price for a pink diamond is $2.1 million.   To break that record, this diamond would need to sell for at least $33,768,000.   Considering that amount is only $5 million above the high-end estimate, it is possible that this record could fall.

A Possible Record-Breaking Diamond


A 12.03-carat Internally Flawless Fancy Vivid Blue diamond could become a record-breaking stone come this November as it goes to auction by Sotheby’s.

The “Blue Moon Diamond”, named for its once-in-a-blue-moon kind of rarity is expected to sell for between $35 and $55 million at their Magnificent Jewels and Noble Jewels auction in Geneva.

The original stone was recovered by Petra Diamonds at the Cullinan mine in South Africa in January 2014.

In it’s original state, it weighed in at 29.62-carats and was quickly sold for $25.6 million to Cora International.   The New York-based firm then spent the next 6 months cutting and polishing the fabulous blue stone to its current form.

If the Blue Moon Diamond does end up selling for more than $32.6 million, it will break the record currently held by the 9.75-carat Zoe Diamond as the most expensive blue diamond ever sold.  If it sells for more than $46.2 million, it will set the record for the most expensive diamond of any kind sold at auction.
