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.


Historic Victory Diamond Highlights Sotheby’s Auction


Sotheby’s Geneva auction of Magnificent Jewels and Nobel Jewels next month has a number of stones that are sure to sell in the millions.   For history buffs, the first on that list is the stunning Victory Diamond.

The Victory Diamond was the largest of 30 diamonds cut out of the rough the 770-carat Woyie River diamond.   Found in Sierra Leone in 1945, the lozenge-shaped Woyie River diamond was the the third largest diamond ever found in Africa.

Named in honour of the Allied victory during World War II, the Victory Diamond is a potentially flawless, type IIa, step-cut 31.35 carat stone that should sell at the auction for between $5 and $8 million.

Also expecting to make headlines at the same auction is a couple of diamonds from the London-based jeweller Graff Diamonds. The first is the Graff Vivid Yellow diamond.   Weighing in at 100.09 carats, it is considered the largest fancy vivid yellow diamonds ever recovered.   The diamond, described as “daffodil yellow” in colour has a hefty auction pre-sale estimate at between $15 and $25 million.   However, with the value of colour diamonds continuing to increase, some of our in-house experts believe that estimate could be a little conservative.

The other major diamond to go under the hammer from Graff is a 103.46 carat, brilliant-cut, round stone.   Many experts consider the gem to be one of the largest known round diamonds. The stone is expected to sell at auction for between $3.5 to 5 million.


Diamond Records

The Orangethe pink star

The colour diamond industry was rocked by record-shattering auction results out of Geneva this week.

At Tuesday’s Magnificent Jewel auction by Christie’s International,  the docket was highlighted by the sale of an almond-shaped fancy vivid orange diamond simply called “The Orange”.

Industry analysts had assumed the stone would sell for around $21 million, a record price for an orange diamond.   Instead, it sold for $35 million, setting two records simultaneously.    At $2.4 million per carat, it was the highest per carat price ever paid for a colour diamond at auction.   It was also the highest total ever paid for an orange diamond in history

The diamond was purchased by a private collector who was present at the time of the auction.   At this time, this person has requested to remain anonymous.

Not to be outdone, Sotheby’s auctioned off “The Pink Star” on Wednesday.   The round 59.60 carat pink stone was graded at Type IIa, a rarity for that colour of diamond.  Industry analysts considered the internally flawless vivid fancy pink stone to be the most rare diamond ever put up on the block.

Once again, the early estimates proved to be conservative as it was assumed The Pink Star would sell at around $60 million.  The diamond ended up selling at $83.2 million, the highest total ever paid for any gem (colour diamond or otherwise) in history.   Details on the buyer have yet to be released.


Sotheby’s has said that the buyer of “The Pink Star” was New York diamond cutter Isaac Wolf, He plans on renaming the stone “The Pink Dream”.
