Round brilliant diamonds are the most popular center stone for engagement rings, but some celebrities stand out from the rest with fancy styles like the emerald cut diamond.

Emerald cut diamonds have been seen gracing the ring finger of celebrities like Jennifer Lopez, Amal Clooney, and Beyoncé. Featuring sleek lines and a step cut that produce a hall-of-mirrors shine, the emerald cut diamond makes a gorgeous engagement ring that exudes a distinct yet sophisticated vintage feel.

Let's take a look at each of these stunning celebrity engagement rings a little closer:

Jennifer Lopez

Before Jennifer Lopez married Ben Affleck, she was engaged to pro baseball player Alex Rodriguez (A-Rod). Rodriguez proposed to her with a 15 carat emerald cut diamond ring in a platinum band. Lopez's engagement ring is said to have cost around $1 million, and is quite rare because of the sheer size and excellent quality.

Amal Clooney

George Clooney chose an engagement ring for Amal that perfectly reflects her sophisticated style. Clooney's ring is in the three-stone style and features a 7 carat emerald cut diamond flanked by a baguette on either side. It is set in either a platinum or white gold setting and has a value estimated to be around $700,000.

Beyoncé

When Beyoncé became engaged to Jay-Z, the BeyHive was certainly buzzing about her ring. Her gorgeous ring is a jaw-dropping, 18 carat emerald cut diamond in a white gold or platinum split-shank setting. Jay-Z reportedly paid about $5 million for it.

While there are many celebrities who own diamond engagement rings in behemoth sizes, none compare to the ring owned by Jackie Kennedy-Onassis.

Jackie Kennedy-Onassis

The celebrity with the biggest diamond engagement ring is without a doubt Jackie Kennedy-Onassis. She received a 40 carat, marquise-cut diamond ring with VS2 clarity from Greek shipping magnate Aristotle Onassis.

It was a far cry from the Toi et Moi-style ring given to her by President John F. Kennedy. Kennedy's ring featured a 2.84 carat emerald and 2.88 carat emerald cut diamond.

Kennedy-Onassis is reported to have only worn her ring from Onassis twice before locking it away in a vault for safekeeping.

A modern day celebrity with the most expensive engagement ring is likely Mariah Carey. Carey's ex fiancee James Packer gave her a 35 carat engagement ring featuring a massive emerald cut diamond. Packer paid $10 million for it, but Carey eventually sold the emerald ring to an L.A. jeweler for $2.1 million.

There doesn't seem to be an average carat size for celebrity engagement rings. Fans expect most of them to be large, but that's not always the case.

When it comes to carat size, celebrity rings run the full gamut: from Amy Adams' 1 carat halo setting to Cardi B's 8 carat pear shaped diamond and Mariah Carey's larger than life 35 carat emerald cut ring.

Celebrities often spend anywhere from a few hundred thousand to millions of dollars on a single engagement ring. However, not all celebrities feel the need to have a stunning engagement ring with the biggest diamonds possible. In fact, some of the best celebrity engagement rings are under 5 carats.

Celebrities like Keira Knightley, Sophie Turner, and Miranda Kerr all have diamond engagement rings that come in under 5 carats. This is despite having large net worths.

Keira Knightley

Knightley's simple ring is a 2 carat diamond solitaire with a platinum band. Her husband, James Righton, paid $40,000 for it.

Sophie Turner

Turner's ring from Joe Jonas showcases a beautiful pear shaped diamond atop a double pavé band. The center stone size falls somewhere between 2.5 to 3 carats.

Miranda Kerr

Kerr's 2.5 carat diamond ring includes a round cut diamond center stone with tapered diamond baguettes on either side of it.

Her ring likely cost about $75,000 to $100,000, a seemingly modest price considering her husband is Snapchat CEO and billionaire Evan Spiegel. Prior to Spiegel, Kerr was married to Orlando Bloom.

Rose gold is a stunning metal color and stands out in a sea of platinum, white gold, and yellow gold bands. You can find celebrities like Alison Brie, Blake Lively, Lauren Conrad, and Mandy Moore sporting rose gold engagement rings on their fingers.

Alison Brie

Brie's ring from Dave Franco features a round cut diamond in a double, diamond halo setting with a thicker rose gold band.

Blake Lively

Coming in at 12 carats with a cost of around $2 million, Lively's ring features a rare oval shaped diamond in pink. The ring's delicate rose gold band is covered in pavé diamonds and complements the color of her light pink oval diamond beautifully.

Lauren Conrad

Simple elegance best describes Lauren Conrad's solitaire setting engagement ring. Conrad's ring features a 2 carat round cut diamond secured with four prongs atop a thick rose gold band.

Mandy Moore

For Mandy Moore, the simpler the ring, the better. Her engagement ring features a round cut diamond in a rose gold setting with a pavé diamond band.

Princess Diana

Probably the most famous sapphire engagement ring in recent history was the ring Prince Charles (soon to be King Charles III) gave to Princess Diana.

Although Prince Charles presented the ring to Diana when he proposed, Diana actually chose the ring herself. Known as the Marguerite, the ring boasts a 12 carat oval Ceylon sapphire surrounded by 14 solitaire diamonds. The ring features a white gold setting.

Today, one way in which Diana's legacy lives on is through this beautiful ring. When Prince William proposed to Kate Middleton her presented her with his mother's sapphire ring.

Victoria Beckham

Although just one of many (she has 15 engagement rings), Victoria Beckham's oval shaped sapphire engagement ring is a stunner. The sapphire center stone is 15 carats and sits in a 4 prong, white gold setting with a band adorned with pavé diamonds.

Mary Kate Olsen

While Mary Kate Olsen's vintage engagement ring doesn't feature a sapphire center stone, it does include 16 calibre cut sapphires surrounding a 4 carat round center diamond. This interesting flower shaped ring design also features a basket setting. It's a fascinating ring that reflects Olsen's eclectic taste.

Lady Gaga

Lady Gaga received a 6 carat heart shaped solitaire from ex fiancee Taylor Kinney. Unfortunately, they broke off their engagement a year later.

Gwen Stefani

When Gavin Rossdale proposed to Gwen Stefani he gave her a thick, gold engagement ring with diamonds around it. Stefani eventually switched it up in favor of a heart diamond ring.

Avril Levigne

In March 2022, Avril Lavigne became engaged to Mod Sun. He gave her a solitaire heart shaped diamond ring with a pavé band. The 5 carat stunner includes a band with two meaningful engravings: "Hi Icon" (the first words he spoke to her) and "Mod + Avril."

The current status of their relationship is unclear.
