Diamond And Ruby Trinkets Of The 'Queen's' Jewel Case

2. The Perfect Pink

Another large pink diamond ring, the Perfect Pink sold for $23 million in 2010. This 14.23-carat beauty was purchased by an anonymous buyer at a Christie’s Hong Kong auction. Again, the high price of pink diamonds stems from their scarcity; Christie’s says that only 18 pink diamonds of more than 10-carats have appeared at their auction house in its 244-year history.

Another reason for the sky-high price: pink diamonds usually display some sort of color modifier, such as purple, grey or orange, but the Perfect Pink shows absolutely no trace of any other hue sullying its pinkness—hence its name.

3. L’Incomparable Diamond Necklace

The Bronze-medal position on our list of most expensive jewelry holds a couple of records. Created by the famed Mouawad firm, the L’Incomparable Diamond Necklace is the most valuable necklace in the world and features the world’s largest internally flawless diamond, the 407.48-carat Incomparable diamond. Complementing the massive yellow diamond are 230 carats worth of smaller diamonds.

What’s more amazing about this piece is that it came to be thanks to a little girl who discovered a rough 890 carat diamond in a rubble pile in Democratic Republic of the Congo in the 1980s. After being sold among numerous dealers and traders, the diamond underwent four years of studying and cutting to reach the point it is at today.
