#9 Irina Shayk
Synthetic emeralds are created in a lab and cost a lot less than the ones that form naturally.
When it comes to celebrity engagements and the rate they end you might hope that famous couples would opt for the less expensive type before they fully commit to a wedding.
That said, Irina Shayk's ring, given to her by Bradley Cooper is sure to contain a natural (and every expensive) emerald.
Unfortunately the couple are no longer together and Shayk is said to have returned the ring.
#8 Halle Berry
Halle Berry's ex-husband Olivier Martinez designed this stunning emerald engagement ring.
But it came to a sorrowful end, firstly when Berry lost the ring at a film festival in Mexico, and finally when their marriage ended 3 years later.
#7 Olivia Wilde
Wilde loves her unique vintage emerald engagement ring given to her by Jason Sudeikis. The antique emerald is presumed to have been first worn in Paris around 1921 but the original owner is unknown.
Olivia told Brides. "I love imagining the story of this ring. Who had it? It's a bit of an aqua emerald, not a deep dark green."
Containing a glittering diamond surrounded by emeralds this is a very special ring and matches Wilde's sparkly green eyes.
#6 Pandora May Droplet Ring
Not an engagement ring, and tbh not actually an emerald, this Pandora May Droplet ring is all about the May birthstone.
Fun and affordable, this is a cute gemstone ring you can wear until you can save up for the real thing. Or get engaged of course.
#5 Natural Emerald Ring
This chunky band from Michael Hill has 1ct of round diamond cut diamonds situated within four round natural emeralds.
Set within a 14ct yellow gold band, it's a great choice for someone who prefers a more practical ring that won't snag your stockings in winter.
#4 Cartier 1895 Solitaire Ring
With POA, you'll have to assume you can afford this one before he pops the question.
Cartier Solitaire rings range from $2500 upwards. But this ring is set with an emerald cut emerald stone, available between 1ct and 1.99ct and paved with a ring of brilliant-cut diamonds.
So, how much? Probably less than the $400 million Bahia Emerald which is said to weigh 381kg and be the world's most expensive emerald ever, but at least $20,000 at a guess.
