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 that all-important decision.

1. Calculate the budget

The first thing to take into consideration is your budget and work out how much to spend on an engagement ring. Traditionally it has been said that you should spend 2-3 months' salary on a ring, however, nowadays it’s much more flexible with people spending anything from a few hundred Euros to a few thousand depending on their budget.

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.

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 their ring. For example, 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. Likewise if they work in a hospital setting, they may not be able to wear their ring underneath gloves if the stone is large so you maybe want to consider an alternative.

It is also a good idea to take note of what jewellery your partner already wears (if any). 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

Making sure the ring fits is a very important step but 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

4. Choose the ring setting

There are many different types of engagement ring settings. The term “setting” refers to how the gemstones are mounted into the metal band that goes around the finger. The ring setting is dependant on personal preference but certain types will help to highlight the beauty of the diamond or gemstone you’ve chosen.

5. Choose the diamond shape

The next detail to think about is the shape of the stone you want on the ring. The shape of the stone takes into account how well the diamond has been cut. Well-cut, properly proportioned diamonds have the best 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 isn't 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. This cut features lots of shimmering facets that make the light dance and can create the illusion of longer, slender fingers. Bold and sophisticated, the oval diamond is a unique shape for anyone who likes to express their individuality.

Emerald-cut stones are sought after for their vintage-style 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.

The princess shape is one of the most popular diamonds shapes, loved for decades for its contemporary look and gorgeous sparkle. Princess-cut diamonds are square-cut stones with pointed corners so are perfect for those who love a more modern style of ring.

A pear shape stone features a round shape that is tapered into a teardrop. Just like oval and marquise diamonds, the flattering pear shape helps to elongate the finger – especially when worn with the point facing towards the nail – and offers unrivalled sparkle..

7. Choose a precious stone

Arguably the most important part of the ring, next, you’ll need to decide on the gemstone that will take centre stange on the engagement ring. Diamonds are thought to be the most traditional stones for an engagement ring but if your beloved leans towards less-than-traditional tastes, there’s a plethora of alternatives for you to choose from.


For many years, engagement rings have featured beautiful, sparkling diamonds. They are the top choice for proposals as they are hardy, durable, and as long-lasting as your love for eachother. They offer beautiful sparkle and depth and you can even find them in a rainbow of different colours so can suitanyone’s individual tastes and style.

8. How to buy

So you’ve worked out how you want the ring to look, you’ve found out the correct size (either by asking or by being sneaky,) and you’ve decided on the right stone, setting, and metal. How do you purchase this perfect ring? There are a number of different options for you to choose from.

Custom made


Ready-to-buy rings are like buying clothes from a shop – they’re easy to find and you know exactly what you’re getting. However, they don’t offer any kind of customisation or personalisation so if you have a specific combination of features you’re looking for, you might not be able to find exactly what you’re looking for. But ready-to-buy rings boast the quickest delivery times as they’re already made and ready to be shipped out to you.
