Colored Gemstone Prices Soar at Bonhams


colored gemstone prices soar at bonhams


Colored gemstones reigned supreme at Bonhams Fine Jewelry sale last week. That is the essence of news reports capsulizing the results of last week;s auction of important jewelry pieces at Bonhams London Auction House.

I like to pass along these reports that relate to colored gemstones for several reasons:

    Readers of the AZGem Gems newsletter are interested in colored gems.
    Rising price trends of important colored gemstone jewelry translates into higher value of quality colored gemstone jewelry owned by our readers.
    I can share many colorful photos of gems and jewelry.

Bonhams reports on the success of this important auction with typical British reserve...

Colored gemstone prices soar at Bonhams London first Fine Jewelry sale of 2015

Period jewelry by Chanel hotly contested with buyers bidding around the world


Rubies, sapphires and emeralds are this year's must-have gems according to Bonhams and its first London sale of 2015 demonstrated the huge appetite for colored stones with fierce bidding taking place in the saleroom, on the telephone and online from buyers across the globe.

Bonhams sells more jewelry lots each year than any other international house and has more dedicated jewelry auctions annually. It has tracked a significant increase in the price per carat achieved for colored gemstones in its auctions over the last decade and has proclaimed 2015 as the year of the colored gemstone.

The Fine Jewelry sale achieved £4.34 million, with 83% sold by value and 128 lots going to new owners.

Highlights of the sale included:

A 21.27 carats sugarloaf cabochon Kashmir sapphire and diamond ring with a pre-sale estimate of £50,000 to £80,000 sold for £290,500, more than three times its estimate.
A 17.97 carats Burmese sapphire and diamond ring also sold for three times its pre-sale estimate of £40,000 to £60,000, achieving a final selling price of £182,500.
A diamond pear-shaped single-stone ring by Harry Winston. Weighing 9.05 carats, the diamond is D color, VS1 clarity, and after a strong bidding war in Bonhams New Bond Street sales room and on the telephones, it sold for £350,5000 to a US bidder.
A 7.10 carats fancy-coloured pear-shaped diamond single-stone ring was the subject of a bidding war between two telephone bidders. The Fancy Light Pinkish Brown, natural color ring sold for more than five times its pre-sale estimate of £15,000-£20,000 and achieved a final price of £117,700.
A 4.54 carats Burmese ruby single-stone ring with a pre-sale estimate of £25,000-£35,000 sold for £134,500. Another Ruby three-stone ring achieved more than seven times its pre-sale estimate of £8,000 to £12,000 with a final hammer price of £76,900.
An emerald and diamond dress ring, circa 1950, sold to an online bidder for £68,500 against a pre-sale estimate of £15,000-£18,000. The emerald is of Colombian origin and weighs 3.25 carats.
A pair of sapphire and diamond earpendants, circa 1950, sold for £92,500 against a pre-sale estimate of £30,000-£40,000. Each earpendant is set with a cushion-shaped sapphire, weighing 10.50 and 9.50 carats. The sapphires are of Sri Lankan origin, with no indication of heating.

Another star performer at the auction was an exceptionally rare retro citrine-set twist necklace by Chanel (circa 1954-71). The signed piece was hotly contested with buyers from the UK, Europe and the US fighting it out in the sale room, online and on the telephone. The highly desirable collectors' piece outstripped its pre-sale estimate by more than ten times selling for £68,500 to Hancocks, London, the well-established jeweler that specializes in rare and collectible jewels.

Jewellery from the 1970s by Andrew Grima continues to be very much in demand by collectors and private buyers. Two pieces by Andrew Grima featured in the auction. A gold and diamond-set 'super shell' necklace sold for £15,000 and an 18 carat gold, wood opal and diamond pendant and ring (circa 1972/73) sold for £8,750.

Jean Ghika, Bonhams Head of Jewelry for UK and Europe, says: "We achieved outstanding results across the board which underlines the buoyancy of the market.

"The sale performed exceptionally well and generated strong interest from buyers in the UK, Europe, the US and Asia. I was particularly delighted to see many of our colored gemstones sell so well, some by up to 10 times their pre-sale estimate, which is an excellent indication of how strong the market is.

"The sale also reinforced the enduring appeal and strong demand for good quality, signed pieces of jewelry such as the Chanel necklace which sold for more than ten times its pre-sale estimate."

Bonhams is now expecting the strong market to be reflected during its next two Fine Jewelry sales in Hong Kong on 3 June and New York on 22 June.


Colored gemstone prices soar at Bonhams - the very wealthy seem enthusiastic about quality jewelry pieces in general, and colored gems in particular. This trend will help your quality jewelry and estate pieces increase in value.

Gem Industry News


Christieís: Elizabeth Taylorís trust owes us $8.8M


liz taylor vs christie's


The New York reports in their Page Six column on the ongoing multi-million dollar controversy between Christie's Auction House and the Elizabeth Taylor Trust...

Auction house Christieís is battling over money with Elizabeth Taylorís trust.

The trouble began when a buyer backed out of an $8.8 million deal to purchase Taylorís Taj Mahal necklace (gifted to her by Richard Burton) at a 2011 auction. But the auction house pre-paid the trust ahead of receiving money from the buyer, who canceled the sale.

Now Christieís wants its money back.
