Four best star engagement rings in 2012

There were a number of A-list engagements and weddings in 2012, but a couple engagement rings stood out the most. According to Us Weekly, the prettiest baubles of the year include that of Jennifer Aniston, Angelina Jolie, Miley Cyrus and Kelly Clarkson.

Aniston's beautiful ring given to her by her longtime beau Justin Theroux is a radiant cut center diamond that amounts to 8 or 9 carats and is expected to be worth $500,000. Jolie's ring from Aniston's ex-husband, Brad Pitt, is valued at the same price, but the emerald cut diamonds and those flanking it are expected to be around 16 carats, the publication reports.

Cyrus's sparkler, given to her by Liam Hemsworth, is a vintage 3.5 carat ring, and even though she is just 20 years old, she is thrilled to be engaged. Clarkson is the latest of the group to say "yes," and her yellow canary diamond with smaller diamonds surrounding it has attracted a great deal of attention.

Even though the vast majority cannot afford these baubles, it is still possible to get similar looks by purchasing costume jewelry such as the 4.54 Carat Cushion Cut Canary Colored Cubic Zirconia 18k Yellow Gold Over Sterling Silver Ring for much less.
