Jewelry connoisseurs have gone crazy for colored diamonds. And their appetites were practically insatiable in 2013.

In October 2013, an 8.77 carat cut-cornered rectangular modified brilliant-cut, GIA-graded Fancy Intense pink diamond sold for $6.3 million at Christie’s New York, coming in at $721,200 per carat. The same auction saw a 3.80 carat round-cornered rectangular modified brilliant-cut GIA-graded Fancy Vivid blue diamond (above) sell for nearly $4 million –a little more than $1 million per carat.

As it turns out, the October auction was a warm-up for the main events in November. A 14.82 carat pear modified brilliant-cut Fancy Vivid orange diamond (The Orange) sold for $35.5 million at Christie’s Geneva. This beauty was also graded by GIA, and at $2.4 million per carat, it earned the highest-ever per-carat price for a gemstone at auction.

Also in November, Sotheby’s Geneva saw the sale of the 59.60 carat the Pink Star – a GIA-graded oval mixed cut Fancy Vivid pink that sold for $83.2 million.  Renamed the Pink Dream  by its current owner, it was expected to fetch $60 million, until a bidding war started. As Russell Shor, senior industry analyst at GIA noted, the price of the Pink Dream was comparable to prices paid for artwork by some of the master painters.

So what’s driving the colored diamond craze?

Hollywood A-listers like Jennifer Lopez, Penelope Cruz, and Oprah Winfrey are wearing them, and it’s no secret that celebrities are often trendsetters. The exceptional rarity of these stones is also behind the frenzy: Fancy-colored diamonds are far rarer than diamonds in the normal color range. Some experts estimate that only 2% of total rough diamond production is fancy colored. The percentage is even lower for fashioned diamonds: Only one out of 10,000 carats of fashioned diamonds displays fancy color, and a diamond’s chances of displaying intense color are even lower – one in 25,000. Heightening the craze is the expectation that the Argyle mine, the main source of natural pink diamonds, will be exhausted by 2020. Add all these together, and you have the ingredients for a serious trend.

Not surprisingly, jewelry shoppers have also caught colored diamond fever. Some retailers and online vendors are selling synthetic colored diamonds or treated-color natural diamonds to satisfy the demand. These beauties available in a rainbow of color choices are becoming more affordable than ever before.

If you’re in the market for a colored diamond, consider looking for a GIA Colored Diamond Report. GIA created the GIA Colored Diamond Grading System in 1994, and has graded important colored diamonds, including the Hope, the Pink Dream, and many others. A GIA report is virtually a requirement by all the big auction houses and other key players. Why not make it a requirement for your next purchase too?

Which do you prefer: colorless or colored diamonds? Do you think colored diamonds are a fad or are they here to stay?

Coral is one of the oldest substances in nature to be used in jewelry. For thousands of years, decorative art objects have displayed this  treasure from the sea. The resurgence of vintage coral items at auctions around the world last fall hints that this favored material has enduring style, blooming in shades from pale pink to deep red. Buyers had more choices of period coral collectibles than in past seasons, and many of the pieces sold quite well.

Many pieces offered at recent auctions date back to a time when the grand jewelry houses began to create more modern designs with new materials, like this carved coral rosebud brooch by Cartier, circa 1955.  The pin also features 18-karat gold leaves accented by round and single-cut diamonds. It sold at Sotheby’s New York in December for $27,500.

Also in December, Sotheby’s London auctioned this exquisite coral choker created in 1948 by Cartier for Wallis Simpson, the Duchess of Windsor. Twenty-three strands of coral beads are joined by a tubular clasp set with carved emeralds and single-cut and brilliant-cut diamonds. Royal historian and biographer Hugo Vickers described this piece of history as a “mixture of the very formal and very special, and also the very informal and very modern.” The necklace – known as a torsade –  sold for more than $180,000.

These vintage David Webb coral and diamond earrings went to one lucky bidder at Christie’s New York in December for $50,000. The surmount (the post part of the earring) sports a coral sugarloaf cabochon surrounded by diamonds, and each detachable pendant suspends a pear-shaped cabochon coral drop, centered in a platinum and circular-cut diamond surround.

A coral, diamond and enamel bracelet from Christie’s New York almost appears like a sea creature itself. Its sculptural design connects hourglass-shaped coral links, each having bezel set diamonds with black enamel accents inlaid into the coral. The bracelet sold at the auction house in October for $15,000.

Demand for quality coral exceeds supply, and the natural material is considered endangered. Today, many coral lovers opt for vintage jewelry, or turn to dyed resin, or man-made simulants as a way to celebrate this ocean treasure.

Fall brings the turning of leaves, the golden glow of pumpkins, and the warmth of fires in the fireplace. While yellow is often associated with the sunny skies of summer, its warm tone is a natural autumn hue, and this fall’s auctions have a number of spectacular yellow diamonds that are fitting for the season.

At Sotheby’s September 24 auction in New York is a 7.02 carat Fancy Intense yellow diamond ring, with an estimated sale price of $140,000 to $160,000. The cut-cornered rectangular modified brilliant-cut diamond has a GIA report verifying that it is a Natural Color Fancy Intense yellow. (Update: final sale price was $173,000)

The geological conditions that create colored diamonds is very rare, which makes naturally occurring shades, like this yellow stone, scarce and highly prized. Read more about how GIA grades natural colored diamonds here (link).

A 5.13 carat square-cut Fancy Vivid yellow diamond is one of a trio of colored diamonds that will be highly anticipated at Christie’s Magnificent Jewels auction in New York on October 15. Alongside a 8.77 carat Fancy Intense Pink and 3.81 carat Fancy Vivid Blue, this Fancy Vivid Yellow is expected to fetch $200,000 to $300,000 at auction. With the rising popularity of colored diamond celebrity engagement rings—Kelly Clarkson was engaged in last December with a fancy yellow diamond like this one—perhaps we’ll see this unmounted stone make another appearance on the finger of a famous celebrity!

As mentioned earlier, a naturally occurring yellow diamond is quite rare, and of course, large sizes are even more rare. Also at Christie’s Magnificent Jewels auction is a commanding 20.04 carat pear-shaped Fancy yellow diamond, mounted in gold and platinum and suspended from a 16-inch fine link chain. This stunning necklace has an anticipated sale price of $500,000 to $600,000.

Earlier this month, Pantone—the worldwide authority on color–determined its color of Spring 2014, called “dazzling blue.” As fashion and home décor designs roll out over the coming months, you will surely see lots of this rich cobalt color, and the fall auctions already have a number of “dazzling blue” pieces up for sale.

Perhaps the most dazzling of all is a 7.59 carat Fancy Vivid blue diamond, part of Sotheby’s October 7 Hong Kong auction, Celebrating 40 Years in Asia. As mentioned in an earlier blog, this special auction is also expected to sell an 118.28 carat colorless diamond for a record-setting amount.

With an expected sale price of $19 million, this blue diamond is also expected to break another record for per-carat price for any diamond. Called “The Premier Blue,” the internally flawless blue diamond is larger in size than most shirt buttons, and its size, vivid blue color, and round cut make it exceptionally rare. The round brilliant cut is rarely used in colored diamonds because it is designed to maximize brilliance and lessen the effect of color.  This stone is the largest round brilliant Fancy Vivid blue diamond ever graded by GIA. (Update: the Premier Blue diamond didn’t find a buyer)

While not a blue diamond, this sapphire and diamond ring is an example of why the Kashmir sapphire with its velvety blue appearance is considered by many to be the most desired of all  gems. The 11.81 carat cushion-shaped sapphire in this white gold ring originated the Kashmir mountains, an intersection of three prominent mountain ranges between Pakistan, India and China. The gem’s exceptional appearance suggests that it came from a gem deposit that was exhausted more than 100 years ago.  The gem shows no indications of heat treatment, a common treatment to enhance color or clarity in sapphires. A natural sapphire from Kashmir of this size and quality is exceptionally rare, which is why it is expected to fetch somewhere between $1.2 and $2.0 million at Christie’s first Shanghai auction on September 26. (Update: final sale price was $1,688,389)

Another important blue diamond is included in Christie’s October 15 Magnificent Jewels auction. As one of three spectacular colored diamonds featured in this sale (read more about the fancy yellow diamond) , this 3.81 carat cushion-cut Fancy Vivid blue diamond is set into a ring and expected to sell for $2.5 to $3.5 million.

While not exclusively blue, the number of sapphires in this colored stone Tiffany & Co. bracelet certainly qualifies it as “dazzling.” This unique flexible strap bracelet is decorated with a rose branch designed from emeralds and yellow sapphires set against a background of round white diamonds. It’s topped off with an “evening sky” composed of emerald-cut sapphires around a crown rose-cut diamond “moon.” The intricate design and detail work makes it a special piece, and is expected to sell between $150,000 and $200,000 at Sotheby’s September 24 auction in New York. (Update: final sale price was $173,000)

As seen on the runways, head-to-toe Winter White is one of the hottest trends for this fall. The jewelry appearing at auction houses this fall seems to follow this trend, as a number of spectacular colorless pieces are coming up for auction.

One of the many important coloress diamond rings being shown at Sotheby’s New York is a 19.51- carat Harry Winston diamond ring. This ring, chosen to lead Sotheby’s Important Jewels auction on September 24, features an E color, VVS2 clarity, 19.51-carat emerald-cut diamond flanked by two triangle-shaped diamonds weighing 2.92 carats. It is expected to sell for between $1.2 and $1.8 million. (Update: final sale price was $2,105,000)

Sotheby’s Hong Kong is celebrating its 40th anniversary in Asia with a special auction on October 7. One of the premier offerings is what it calls “the greatest white diamond ever to appear at auction,” a 118.28-carat, D-Flawless oval diamond.

The diamond, described as an egg in both size and shape, is the largest D color Flawless diamond ever to appear at auction. It was discovered in Southern Africa in 2011, and the winning bidder will receive naming rights. This magnificent diamond is estimated to sell for $28 to $35 million, which would be the highest price paid for a white diamond at auction. The current record is held by the 101.73 carat D-Flawless Winston Legacy, which sold for $26.7 million in May. (Update: final sale price was $30,600,000. A new record.)

While the oval diamond is likely to break the sale price record, a diamond necklace by Van Cleef & Arpels is also making history as one of the noteworthy offerings in Christie’s first Shanghai auction. The auction is being described as a “celebration of the great artistic traditions of both East and West,” and includes jewelry, watches, wine, and fine art.

Created in 1950, this platinum bib-style necklace was designed to complement the silk, lace, and brocade evening gowns of post-war couture fashion. Featuring a line of baguette-cut diamonds suspending a graduated fringe with baguette, brilliant, and marquise-cut diamonds, Van Cleef & Arpels considered the necklace so unique that they patented the design.  The estimated sale price for the rare piece is between $750,000 and $1 million. (Update: final sale price was $836,768)

The piece fetched $118,750, more than its estimated value of $75,000 to $100,000.

The exquisite  bracelet dates to 1930 and features an openwork band set with both carved and cabochon rubies,  emeralds, and sapphires with 7.00 carats of baguette, old European, and single-cut diamonds.

Spring flowers were in full effect this auction season with two outstanding multi-color gemstone necklaces.

On April 17, Sotheby’s New York auctioned a beautiful necklace featuring diamonds and colored stones stylized as thirteen anemone flower heads of various hues. The necklace is a combination of 46.86 carats of round near colorless diamonds, 7.45 carats of black, pink and yellow diamonds, in addition to pink sapphires, amethysts, garnets, iolites, pink tourmalines and spinels. This Michele della Valle design sold for $149,000, in line with its estimated value of $125,000 to $175,000.

On May 15th, Christie’s in Geneva auctioned a 1961 Bulgari platinum, sapphire and diamond flower necklace at their upcoming “Magnificent Jewels” sale. This necklace, much like the Michele della Valle “anemone” necklace, is designed as a series of graduated flower heads. The stunning floral design is created with circular-cut sapphire petals and pistals as well as oval-shaped diamond pistils and pear-shaped diamond petals . This outstanding piece was estimated to sell between $310,000 to $400,000, and sold for $535,061.

The post Spring Auctions Showcase Part 6: A Shower of Flowers appeared first on GIA 4Cs Blog.

As the saying goes, “April showers bring May flowers,” and May’s birthstone – emerald – perfectly symbolizes this renewal of life. It comes as no surprise, then, that emeralds have been such a focal point of auctions this spring.

Christie’s auctioned a stunning emerald and diamond ring on May 15 in Geneva. The platinum ring is set with an exceptionally large cushion-shaped Columbian emerald weighing approximately 23.28 carats, and diamond line shoulders. The estimated value of the piece was $1,300,000 to $1,800,000; however, since a natural emerald from Columbia of this size  is so rare, it could sell for significantly more.

Christie’s New York auctioned a fancy color diamond, emerald and white diamond ring on April 16, ultimately selling for over three times its estimated value. This special ring features a 9.72 carat cushion-cut Fancy Intense yellow diamond surrounded by  pear-shaped emeralds and diamonds, mounted in gold and platinum. The piece, which had an estimated value of $180,000 to $220,000, sold for $699,750.
