As 2019 comes to an end, we're ringing in 2020 by looking back at some of the best celebrity engagement rings of the last decade.

Like every other decade, there have been lots of celebrity engagements — some ending in happily ever after, others ending in divorce, and some not even making it down the aisle. But regardless of the outcome, the rings were honestly worth the journey (at least for us).

Here are the 10 best celebrity engagement rings of the decade:

2. Jenifer Lopez

J. Lo's 16-carat emerald diamond engagement ring to Alex Rodriguez estimates $1.8 million. The two have been dating for about 2 years and I can't wait to see the wedding photos from this over-the-top wedding.

3. Hailey Bieber

According to Harper's Bazaar, Justin Bieber gave Hailey Baldwin an engagement ring that cost an estimated $500,000.

4. Kate Middleton

We started the decade with a royal wedding between Duchess Kate & Prince William. William gave Kate a £300,000, 18-carat oval sapphire surrounded by 14 diamonds that his mother wore when she was engaged to Prince Charles. The two married in April 2011 and have three lovely children together.

5. Lady Gaga

Mother Monster's 6-carat heart-shaped diamond from jeweler Lorraine Schwartz cost around $500,000, but we never got to see a monster wedding since she and ex, Taylor Kinney, broke up in 2016.

6. Kim Kardashian West

The entertainment world's royal engagement. Kim Kardashian got engaged to Kanye West on October 22, 2013 with a 15-carat D, flawless cushion-cut diamond from jeweler Lorraine Schwartz that goes for $2 million, and married in 2014. The two already had their oldest daughter, North, when they were engaged, so they were able to celebrate their lavish wedding in Italy with their entire family. They just celebrated their five-year anniversary and has since grown their family with Saint, Chicago, and Psalm - oh, and Sushi, their puppy.

7. Princess Beatrice of York

Princess Beatrice became engaged to Edoardo Mapelli Mozzi in Italy around September 2019 and they'll get married in 2020 - what a way to start the decade with a royal wedding! Princess B's ring was designed by Edo in collaboration with the British jewellery designer Shaun Leane.

8. Amal Clooney

When Amal snatched up George, it felt like my world had fallen to pieces, but the emerald-cut 7-carat diamond with two tapered baguettes $750,000 ring that he gave her made me realize that I, too, can find my George Clooney.

9. Gabrielle Union

Gabrielle and basketball star Dwayne Wade got engaged in 2013 and married a year later. The 8.5-carat cushion-cut diamond from Jason of Beverly Hill goes for about $1 million.

10. Emma Stone

What a way to end the decade than with a proposal! Emma Stone & Dave McCary got engaged around the beginning of December (or at least that's when they announced the engagement) and the ring was not what most people expected. It's a bit nontraditional, but lovely because its center is a pearl instead of the average diamond you see stars wear. Dave chose Tokyo-based designer Kataoka to design the gorgeous ring and it only cost $5000!
