Diamonds! Jewels! and Rings, OH MY!

Sigh... it's been a rough day.  But, do you know what makes bad days better?  Antique Jewelry.  For the past hour, I've been perusing Christie's and feeling infinitely better than I did just a few hours ago.
How could these pieces not make even the worst of things better?

An early 19th century gold and silver-mounted amethyst and diamond cluster ring- Lot 256;

Only $1700! (I say only because I know what is to come)

An Important Coloured Diamond Ring by Van Cleef and Arpels; Lot 2364;

Estimated around $300,000

BRACELET ART DECO DIAMANTS, PAR BOUCHERON- SO, SO Cool; 

For sale at Paris Auction; Estimated at up to $150,000.

Everyone, let's have a collective "le sigh"
