Blue Diamonds To Lead Hong Kong Magnificent Jewels & Jadeite Auction Next Month

On October 3, Sotheby’s will launch its fall/winter auction in Hong Kong. It is showcasing several important fancy color diamonds, in a range of colors, from pink to blue to some important vivid yellow diamonds. This review will discuss some of the attention getters in my opinion and that are of great importance. This time around I am reviewing them from their order of offering rather than valuation.

 

A 1.62 carat Fancy Purple-Pink diamond is a rare colour combination, with a VS2 clarity. It is valued between $230k to $319k total or $142k to $197k per carat. The valuation falls under the the range of current market prices for such a size.

A rare 1.53 carat, Fancy Vivid Green Diamond with a VS2 clarity will be offered. It is not very often that we see such rarity in an auction. The last fancy vivid green diamond that was offered at auction was the 1.64 carat with an SI2 clarity. It was offered by Sotheby’s in New York on April 26, 2017. It was sold for $739k per carat. This 1.53 diamond is being valued between $1.53 million to $1.92 million or $1 million to $1.25 million per carat. The large difference can be attributed to the fact that the current offering is a VS2 clarity, and that the vivid green has a strong depth of color. on the other hand, the difficulties that this diamond will face would be the fact that it is very difficult to evaluate such a rare color. Green diamonds are usually acquired by collectors rather than investors, and after the auction we will know what appetite collectors had for it.

Another extremely rare color for collectors is this 1.38 carat, Fancy Vivid Bluish Green, with an SI2 clarity. It is valued between $715k to $920k in total or $518k to 667k per carat. As we see, compared to the 1.53 carat vivid green above, a secondary, yet a rare bluish color, brings down the valuation by half.

A wonderful 1.42 carat, Fancy Intense Blue diamond with an Internally Flawless clarity is being offered. Both size and clarity are becoming rarer as less  new blue diamonds are coming out on the market from the ground. In this case, this diamond is coming back on the market after being away for over 16 years. The certificate is from 2002. It is valued at between $510k to $765k in total or $359k to $539k per carat. Back in 2002, there was a 2.18 carat Fancy Intense blue diamond that was sold at auction for only $180k per carat. A 2.05 carat Fancy Intense blue diamond with Internally flawless clarity was sold for $1.3 million per carat at the end of 2017. What a difference in valuation over 16 years!

A 4.31 carat Fancy intense Purplish Pink Diamond is being offered. It seems that the clarity is of low grade, most likely an I clarity. The valuation is also quite low, suggesting that the color may not be strong at low, and may even be closer to a strong Fancy Purplish Pink. It is valued at $1.11 million to $1.28 million total or $257k to $300k per carat, which would be the range of value for a nice Fancy Pink diamond.

The second session of the auction will offer even more exciting fancy color diamonds.

 

A small 0.87 carat Fancy Blue with an SI1 clarity is being offered for $51k to $83k in total or $58k to $95k per carat.

A perfect 11.87 carat, Fancy Vivid Yellow Diamond is offered to the public. What makes this diamond unique is the fact that it is Internally Flawless, and has excellent Polish and Symmetry, which is rare for fancy color diamonds in general. It is valued between $1.53 million to $1.92 million or $129k to $162k per carat. These are strong valuations as there are also vivid yellow diamonds offered at much less on the market. This is a unique diamond indeed.

A wonderful 3.47 carat, Fancy Intense Blue Diamond with a VS1 clarity is offered. It is valued at between $2.625 million to $3.5 million in total or $756k to $1 million per carat. It is rare to see a fancy intense blue over 3 carats these days so I expect to see a strong result here. As they become rarer o the market we will see higher prices paid by investors.

Not often do we see a rare fancy color diamond as a round brilliant shape due to lose of color in this shape. Even more so with an Internally Flawless clarity. This 3.64 carat, Fancy Pink diamond is valued at $1.41 million to $1.79 million or $387k to $492k per carat. It is a strong price per carat, yet it is rare. Let’s see how it actually performs at the auction.

A spectacular pair of earrings with 8 rare, round shape, Fancy vivid Yellow diamonds ranging from 4.53 carat to 8.43 carats (totalling 51.17 carats) with clarities ranging from VS2 to Internally Flawless are offered. These earrings are evaluated at between $4.85 million to $6.12 million or $95k to $120k per carat. This price range is usually reserved for fancy vivid yellow diamonds of excellent color and size (normally over 10 carats), but in this case due to the rarity of the whole 8 diamonds, we might end up with a surprise at the auction.

The last lot of the evening and perhaps the most important piece is this 5.00 carat, Fancy Vivid Blue Diamond with a VS2 clarity. It is valued at $12.49 million to $15.29 million or $2.5 million to $3.06 million per carat. In the 5-10 carat category, there has only been a single diamond that reached over $3 million per carat, which is the 9.75 carat, pear shape,  that was sold for $3.3 million per carat back in 2014, and is responsible for vivid blue diamonds to be considered so rare.

There are two important things to consider which can negatively affect the value of this diamond. the fact that it is a 5.00 and it’s VS2 clarity. If at any time, this diamonds get a chip by accident and falls under 5.00 carat, it will have a huge price depreciation per carat. If it was 5.03 for example, then it could be fixed ands till remain over 5.00 carat. Also, the clarity of VS2, although rare, is still less favourable by investors who usually look for a VS1+ clarity. Let’s see how the auction takes it.

As the fall/winter auction season takes off, we should get a better feel of how the rest of the year will be for fancy color diamonds. I know that for exotic cars, works of art as well as for rare spirits, investors have been very optimistic and have been opening their wallets a lot easier. Feel free to comment or ask any questions.
