Emma Stone is the latest celebrity to get engaged, with her fiancé Dave McCary announcing the news on Instagram.

The two have been dating for two years, and the photo shows Stone showing off her new sparkler. Although the snap is a little blurry, what we can see of the ring is both classic and quirky – just like Stone. It looks to be a central diamond surrounded by smaller ones forming a star-like shape, with even more diamonds on the thin band.

This is likely to be one of the last big celeb engagement announcements of the year, capping off a bumper 2019 for famous faces in love. Here are some of the brightest engagement rings of the year…

1. Princess Beatrice and Edoardo Mapelli Mozzi

Princess Beatrice announced her engagement to property tycoon Edoardo Mapelli Mozzi in a sweet series of photos taken by her sister Eugenie. The last snap features a close-up of the ring; a round diamond with tapered baguettes on either side.

The ring was designed by British jewellery house Shaun Leane in collaboration with Mozzi. Jewellery designer Arabel Lebrusan of Lebrusan Studio said at the time: "Following on from the revival of quintessential art deco style, this ring is a wonderful example of how to capture that era and include a personal and modern twist."

2. Sarah Hyland and Wells Adams

Modern Family actor Sarah Hyland got engaged to reality TV star Wells Adams back in July, and she posted close up videos of the ring on Instagram with the jokey caption: ‘Blinded by the [sun] or the [ring]? #wouldyoulikesomeapple.’

She’s not wrong – the Lorraine Schwartz sparkler certainly is huge, in an oval shape on a simple thin band.

3. Jennifer Lopez and Alex Rodriguez

However, the prize for largest rock of the year definitely goes to Jennifer Lopez – a woman who isn’t known for doing things by halves. Ex-baseball player Alex Rodriguez popped the question in March when the couple were on holiday in the Bahamas, and he certainly didn’t disappoint with a massive emerald cut sparkler.

The ring nearly takes up half of JLo’s finger and although no official details have been released, jewellers speculated the diamond is between 15 and 18 carats, according to CNBC.

4. Katy Perry and Orlando Bloom

Katy Perry’s ring is one of the most unusual of the year. Orlando Bloom seemingly proposed on Valentine’s Day, and Perry posted a picture of the two on Instagram with the caption: ‘Full bloom.’ Not only is this a nod her fiancé’s name, but also a reference to the shape of the ring.

The centrepiece of the engagement ring is an oval-shaped pink stone, surrounded by eight white diamonds to make it look like a flower. Perry is known for her eclectic style, so it’s no surprise Bloom went for a quirky ring.

5. Katherine Schwarzenegger and Chris Pratt

Chris Pratt proposed to Katherine Schwarzenegger in January with a simple but impactful sparkler. The large diamond is in a classic cushion cut style – square or rectangular with rounded edges – in a solitaire setting.

This suits both Pratt and Schwarzenegger’s style; elegant and timeless. They wasted no time walking down the aisle and got married in the summer – her in a classic white wedding dress and him in a sleek suit, both by Giorgio Armani.

6. Alizee Thevenet and James Middleton

James Middleton proposed to girlfriend Alizee Thevenet in October. Her ring features a large dark stone surrounded by smaller diamonds on a thin, simple band – and people couldn’t help but draw comparisons to Middleton’s sister’s ring. The Duchess of Cambridge’s rock – which is an heirloom from the late Princess Diana – is basically the same, but cut with a more oval shape.

7. Cressida Bonas and Harry Wentworth-Stanley

Harry Wentworth-Stanley proposed to Cressida Bonas with a ring that matches her style perfectly – vintage and with a quirky edge. The rock looks to be a large central diamond surrounded by a double halo; the first being red rubies, followed by another layer of smaller diamonds. It comes as part of a trend for modern brides gradually turning away from the classic diamond engagement ring style, searching for something a bit more unique.
