For a ‘forever’ piece of jewellery, and one that’s been gracing prospective brides’ left hands since ancient Roman times, you might assume that engagement rings were immune to the impact of shifting trends. Thankfully the iron rings of old have been replaced by decorative and meaningful designs that embrace creativity and innovation while also nodding to the past and conveying the unique style of the wearer.

From sought-after designs popularised by Royal engagements to demands for sustainability and a move towards unconventional cuts, gems and bands, here are the 2020 engagement ring trends to bookmark.

Halo Engagement Rings (with a Twist)

Popular engagement ring trends 2020 1

Halo engagement rings aren’t dropping off the radar anytime soon, but the classic lineup of small diamonds encircling a round or cushion cut central gem has evolved for 2020 according to jewellery designer and certified GIA gemologist Emma Clarkson Webb:

“Over the past few months I have been seeing a huge demand for halo rings, in contrast to the trend for three stone rings which I saw at the beginning of the year. Hexagonal and octagonal shaped styles are particularly popular.”

With the Duchess of Sussex’s three stone engagement ring still inspiring ring designs at the beginning of the year, why the sudden passion for halo settings during the latter half of 2020? Emma underlines the appeal:

“I think that the halo setting is having a real moment because it’s a wonderful design that offers up an opportunity to buy or create a very impactful style that also isn’t prohibitively expensive.”

Halo ring designs are quite literally more cutting edge than ever – from ‘hidden halos’ featuring small diamonds set below the centre gem to halos floating on thin, delicate bands and alternative shapes, see below for serious halo engagement ring inspo.

Green and Blue Engagement Rings

Popular engagement ring trends 2020 9

Emeralds and sapphires are making a real splash according to Emma:

“Coloured gems continue to be ‘king’ as far as 2020 engagement rings go. Blue and green stones such as sapphire, tsavorite and emerald are especially popular.”

If you’re feeling green fingered, Emma has a nugget of advice to consider before you rock up at the jewellers:

“Emeralds are softer than diamonds and many other precious stones and can be more susceptible to damage. For this reason I often recommend tsavorites and tourmalines to clients who love the vibrancy of an emerald but want a more durable gem.”

If you are set on an emerald ring, by no means panic – just treat it with some TLC (read our guide to looking after your engagement ring at home for peace of mine).

Mixed Metal Engagement Rings

Popular engagement ring trends 2020 21

Emma emphasises that sticking to one consistent metal shade is no longer de rigeur. 2020 trends indicate that we’re increasingly mixing our metals:

“Mixed metal mounts that combine rose, yellow and white gold are really picking up interest. 

“There used to be very set rules about not mixing golds but I think that both men and women are becoming much more adventurous when it comes to choosing or designing engagement rings. They’re seeking a piece of jewellery that is unique to them, rather than the cookie-cutter diamond ring that was once very much in vogue.”

It seems that couples really are mixing up engagement ring tradition for 2020, as Emma confirms:

“I am seeing a real demand for mixing different cuts of diamonds within designs; combining baguettes with rounds, for example. It’s a great way of referencing art-deco jewellery but in a very modern, unique way.”

Bespoke engagement rings have long been a popular option but never more so than now, according to Emma:
