Agatha Christie Diamonds = Big Pay Day!

Agatha Christie

Did you hear about the Agatha Christie story about the mysterious trunk purchased for less than $200 (CAD) that turned into about $80,000 worth of diamond jewelry?

This story doesn’t take place in an old mansion or on the Orient Express, it happened for real for a fan of the late author,  Jennifer Grant.

In 2006, Grant purchased a trunk at a sale in the author’s estate in Devon, England.   Inside the trunk was a strongbox that she decided to pry open with a crowbar 4 years later.  Located inside was a diamond brooch and a three-diamond ring.   These pieces became part of Bonhams’ Jewelry auction on October 8, 2014.

Leading up to the auction, industry experts assumed the ring would sell for for between $5,000 and $9,000 while the brooch would sell for between $10,000 and $14,000 while .   The sale of these two items blew away those predictions as the ring sold for a whopping $39,277 and the brooch sold for an even more impressive $49,377!

As per National Jeweler, the pieces were purchased as a gift for his wife by the husband of Sophie Kinsella, famed author of the Shopaholic series of novels.

“The Eye of Time” brooch features rows of diamonds surrounding the “eye” with a blue enamel watch face set as the “eyeball”.   It was sold for $1.2 million (CAD) at auction in May 2014 by Sotheby’s as part of their Impressionist and Modern Art Day Sale.


A pair of yellow gold ear clips, stylized to look like telephone receivers featuring brilliant-cut diamonds on both ends along with rubies and emeralds.   These pieces were sold at auction in November 2010 for $53,832.


The “Tree of Life” necklace features leaves made of gold along with 20 brilliant-cut diamonds spread throughout the piece.   The necklace was part of the Sotheby’s London Fine Jewels auction in December 2011 and sold for $52,004.
