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.
