Jewelry is a favorite topic for many people, and it's especially exciting to learn just how expensive some pieces can be. Whether you're a jewelry lover or you're just curious, you'll definitely find something interesting in this list of the world's most expensive pieces of jewelry!

The Cullinan Diamond

This one of a kind blue diamond ring stunned countless people when it went to auction in 2009. In fact, it was so well-loved by people at the auction that it managed to sell for an impressive $9.69 million. You might find sea glass necklaces with a similar blue tint, but it's hard to say if they could ever match this diamond ring in price.

The $10 Million Ring

This ring contains a 6.01 carat blue diamond as a centerpiece. Framed by two smaller pink diamonds, this ring is probably one of the most expensive cotton candy-looking things ever sold. And anonymous bidder paid $10 million for it, hence its name.

The Pink Graff

If you combine a love for the color pink with a love of diamonds, you'll get the Pink Graff ring. This famous diamond came from the mines of South Africa and is mounted with two additional white Graff diamonds, adding up to a grand total of $11.8 million.

Wallis Simpson’s Panther Bracelet

This bracelet certainly rivals some of the most delicate sea glass bracelet designs out there. Crafted from black and white diamonds and emeralds, it is said to have been owned by King Edward VIII at one point in time. With so many precious gems, it's no wonder that this piece sold at auction for a whopping $12 million.

Heart of the Ocean Diamond

The original Heart of the Ocean actually still lies at the bottom of the ocean, as it was carried on the Titanic. While it's no sea glass pendant, it very well may wash ashore among the sea glass someday. But a Harry Winston Sapphire replica holds an estimated price tag of almost $20 million.

If you can't afford jewels like this, don't worry. Some of the most beautiful jewelry is crafted from sea glass. Over the last 10 years, collecting and crafting with sea glass has become even more popular. From delicate sea glass bracelet designs to sea glass wedding rings, there are endless possibilities. And they're all well within your budget.
