How to choose the perfect engagement ring

There are many different factors to consider when choosing an engagement ring - especially if you’re planning a surprise proposal for your partner. Here are some tips to think about when making a decision.

1. Calculate the budget

Working out how much to spend on an engagement ring can be tricky. Traditionally it has been said that you should spend 2-3 months salary on a ring. Nowadays, however, this figure is much more flexible.

Rather than trying to save a full 3 months worth of salaries before you’re able to propose, make use of our engagement ring calculator to work out how much you can reasonably afford to spend. Diamonds Factory also offers finance options for when you find the perfect ring.

2. Choose the ideal style

Choosing “the ring” should be a truly personal experience, where style is carefully considered to create the design of your partner’s dreams. Take their style and hobbies into consideration when choosing a ring. Are they very active or play a lot of sports? This may affect the size of the stone or ring that you end up choosing.

It is also a good idea to take notice of what jewellery your partner already wears if any at all. For those who like to swap and change accessories based on trends, opt for a more traditional engagement ring such as the classic solitaire setting or princess cut stone. These will work with every look they pull together. For those who like to stick to staple pieces every day or prefer to keep a carefully curated capsule wardrobe, a more creative, stand out design may fit with the styles they are already used to wearing.

3. Get the ring size right

We know that not everyone knows their ring size - and that’s ok! Here are some ways you can find the perfect ring size for you or your partner.

5. Choose the diamond shape

The next detail to consider is the shape of the stone. The shape of a stone takes into account how well the diamond has been cut. Proportional, well-cut diamonds deliver the highest amount of sparkle.

Diamond shapes are categorised into two groups: round diamonds and fancy shape diamonds. Round diamonds are the most traditional diamond shape while fancy shape diamonds refer to any diamond that is not round. Diamonds Factory offers princess, cushion, emerald, oval, pear, marquise, heart, Asscher, and radiant fancy shaped stones so it's worth browsing through them all to find something your partner will love.



An oval-shaped diamond is a really elegant stone. Cut into an elongated circle, this cut features shimmering facets that make the light dance and can create the illusion of longer fingers. Bold and sophisticated, the oval diamond is a unique shape for a wearer who likes to express their individuality.

Emerald-cut stones are sought after for their understated glamour and eye-catching depth. The octagonal step cut features parallel, rectangular facets, and the large, open table (top face) highlights the stone’s colour and clarity. The emerald cut is a great choice for those seeking an Art Deco-inspired ring style.

Loved for decades for its contemporary style and gorgeous sparkle, the princess cut is one of the most popular fancy shapes. Princess-cut diamonds are square-cut stones with pointed corners so are perfect for those who love a contemporary style.

The pear shape features a round shape that is tapered into a teardrop and offers an extraordinary display of light. Like oval and marquise diamonds, the flattering pear shape helps to elongate the finger—especially when worn with the point facing towards the nail.

6. Choose a precious metal

Aside from the gem itself, the metal of the ring band is another important detail to take into consideration.

If you’re buying for someone else, it's best to ask them what they like or what suits them as different metals suit different skin undertones or pay attention to the colour of metal they wear on a regular basis.

If you’re buying for yourself, stay true to your tastes and pick something that speaks to you - it’ll be with you for a long time after all.

7. Choose a precious stone

Arguably the most important part of the ring, you next need to choose the gemstone. Diamonds are considered the most traditional stones for an engagement ring but if your beloved leans towards less-than-traditional tastes, there’s a plethora of alternative stones for your to choose from.


Engagement rings traditionally feature beautiful, sparkling diamonds. They are the top choice for proposals as they are hardy, durable, and as long-lasting as your love for your partner. They offer gorgeous sparkle and depth and you can even find them in different colours so can be suitable for anyone’s individual tastes.

Emerald jewellry can trace its roots back centuries and is a highly sought-after stone. These deep green gems make for a really unique engagement ring and they have exquisite depth to them and have long been considered the stone of love and truth.

Giving your loved one a sapphire engagement ring is a great choice for those who love to show off their individuality. Sapphires are almost as hard as diamonds, are considered to be rarer, and are utterly unique, so are just as precious and durable and the perfect alternative to diamonds.

If you’re looking for the non-traditional in every aspect for your wedding and marriage, rubies pave the way for a beautiful and unique ring. Although not as durable as rubies or sapphires, rubies are still one of the most hard-wearing gemstones, enabling your loved one to wear it for years to come.

8. How to buy

So you’ve got the right size, you’ve chosen the setting and shape, and found the perfect stone for your ring - how do you go about purchasing it? You have a number of options to consider.

Custom made


Ready-to-buy rings are like buying clothing from a shop - they’re easy to find and you know exactly what you’re getting. They don’t offer any kind of customisation or personalisation but they boast the quickest delivery times as they’re already made and ready to be shipped out to you.

Engagement ring FAQs

Here’s a selection of carefully curated FAQ’s to get you through picking an engagement ring for your partner:

Traditionally, it is said that you should spend up to three months’ salary on an engagement ring for your partner. However, the amount you spend on an engagement ring should be down to you and how much you feel comfortable with spending.
Engagement rings are a big investment and purchasing one can be a major financial decision. Some people prefer to pay by taking out engagement ring finance, even if they have the cash, as it means that they do not need to spend their savings in full and the payments can be spread across a certain amount of time.

There are a number of finance options available depending on the repayment period that suits you. If you wish to take out engagement ring finance, apply by selecting the finance method of payment during checkout or speak to a member of our sales team who will be able to help.

According to our research, the average amount of money spent on an engagement ring is around £1865 in the UK. However, this varies region by region and also depends on the age of the individuals getting married.

Tradition aside, the amount you choose to spend should be based on personal preference and budget, as there are numerous ring styles and stones available at a range of prices.
There are many theories proposing how much money should be spent on an engagement ring, with anywhere between one to three months' worth of salary being the most commonly known. However, rather than following a particular rule, the amount you spend on an engagement ring should be what you are able to set aside for it, and no more.

A good understanding of the specifications that affect an engagement ring's value, such as diamond carat and cut, will help you find the perfect ring. Check out our engagement ring buying guide for more information on how to choose the best diamond for your budget.

The cost of the engagement ring you buy should be based on your annual salary, monthly expenditure, current savings, and the amount of time you have before you want to pop the question. Our engagement ring budget calculator can help you determine how much money you will be able to save for your ring based on your proposal timeline. Whatever your budget, there is a ring out there for you!
