The Nature of Diamonds - The Incomparable

Even though the Mammoths and Mastodons: Titans of the Ice exhibit was very interesting, The Nature of Diamonds exhibit is the reason I went to Chicago yesterday.  This exhibit will close at the Field Museum on Sunday.  It was fabulous!  The first part was a meticulous and extensive scientific examination of how diamonds are formed, their physical properties such as light dispersion (of which, surprisingly enough, are exceeded by CZs~!) and thermal conductivity, why they are concentrated in certain areas of the world, etc - quite thorough and informative but not really the part I wanted to see.

The second part was an awesome display of jewelry and unmounted stones.  It was SO worth my long, long day!

The exhibit included The Incomparable, graded by the GIA in 1988 as a 407.48 carat internally flawless diamond categorized as having a fancy brownish-yellow color.

The Incomparable, initially named The Golden Giant,
was exhibited with some of its 14 "satellite" stones - all gorgeous.

Here's a picture of it with its special stand:
