Round 1: I'm not the winner

So I had this great idea - encouraged by an article on my jewelry supplier's site - to dye some pearls. Not any dye job either, mind you, but a lovely ombre blue. Imagine - a pearl necklace that naturally shades from light to dark blue - how lovely would that be!

I understand the concept of ombre, and since I've seen pearls in every shade imaginable, figured I could make this work. I'm an engineer after all!

I purchase a packet of the darkest blue I could find (since I want some REALLY blue), and patiently dipped my pearls in blue water over the stove. (No, I'm not sharing all the details, in case it does finally work) After 30 minutes, I rinse...and instead of blue ombre, I have all one shade of blueish-grayish-purple.

Admittedly, it's a pretty shade - it's just not what I want! (That white one is the original color, just for contrast)

Got to figure out what happened, and how to make the next batch successful.
