The Color Diamonds of Bonham’s Fine Jewels Auction

With the fall auction season beginning to heat up, diamond industry eyes are looking toward Bonhams Fine Jewelry auction coming up on September 17.   The feature piece at the auction is the Duke of Windsor’s Diamond Frog which is being sold alongside a diamond brooch with the stones set in the formation of the Prince of Wales’ feathers, the badge of the Prince of Wales (pictured below).



The pieces together are expected to sell for more than $16,000 (CAD) but we focused on out these five color diamond pieces of jewelry.

1.  A Fancy Brown Yellow Marquise-Cut Diamond Ring


The most interesting color diamond piece in the auction, the centrepiece of the ring is a 12.22-carat Fancy Brown Yellow marquise-cut diamond.   The piece, which is expected to sell for between $140,000 and $180,000 also features a 2.40-carat border of tapered baguette-cut diamonds.

2.  An Argyle Purplish-Pink Diamond Ring


The stone may only weigh 0.80 carats, but this Fancy Intense Purplish-Pink Argyle diamond is stunning.   The ring also features pave diamond shoulders and is predicted to sell as high as $150,000.


3.  A Fancy Yellow Diamond Pendant


The focal point of this piece circa 1905 is a Fancy Vivid Yellow pear-shaped diamond weighing in at 2.93-carats.  Suspending the stone is a chain necklace via knifewire connectors with single-cut diamond detail, mounted in yellow gold and platinum.   The pre-auction estimates for the sale of this pendant are between $45,000 and $63,000.

4.  A Fancy Cushion-Cut Diamond Ring



This 7.50-carat Fancy Brownish Greenish Yellow diamond is expected to sell for between $45,000 and $54,000.   The cushion-cut stone is surrounded by scrolling old brilliant and single-cut diamond shoulders


5.  A 1920s Era Brownish-Yellow Diamond Ring


A ring befitting the jazz age of the 1920s, it features a Fancy brownish-yellow diamond weighing in at 4.73 carats.   The piece also features a mount of 0.30 carats of white diamonds.   This might be the steal of the auction with an estimated sale price of $27,000 to $36,000.
