So, you’ve made the exciting decision to propose to your partner, now what? Engagement ring shopping can be both exciting and stressful. The ring you choose to give to your partner is a special representation of the love you have for them. 

But how do you know which ring to choose for your partner? With so many options to pick from, what is the “best” diamond size for your partner?


How Do You Determine Diamond Size?

Diamond size is determined by carat. A diamond’s carat is the measurement of the diamond’s weight. There can actually be a surprising visual difference between carat sizes. For example, a 1.5 carat diamond is noticeably bigger than a 1-carat diamond. 


Deciding on a Diamond Size

There are a few factors to consider when deciding on a diamond size for your partner’s engagement ring. You have to factor in both your budget and your partner’s wants. Knowing these two things will make choosing a diamond size a much simpler decision.


Figure Out Your Budget

On average, Australians spend about $5000 on an engagement ring. This may sound like a scary number but knowing what you and your partner are looking for in a ring can make budgeting easier. Choosing a diamond size that’s within your budget and matches your partner’s preference is key to choosing the perfect ring.


Know Your Partner’s Style

Whether the proposal is going to be a surprise or not, it’s a good idea to have a discussion about engagement rings with your partner at least once before choosing a ring. This will help you get a better idea of what your partner wants. Finding out what cut and colour your partner prefers for the diamond will make it easier to choose a size.

If you don’t want to ruin the surprise, a simple way to determine your partner’s taste in rings is to look at what other jewellery they own. Does your partner wear extravagant, eye-catching jewellery? This could indicate that a bigger diamond, like a 1.5 carat size, could be a good choice. If your partner tends to wear understated, simple jewellery, a smaller sized diamond, say a .5 carat diamond, might be more suitable.

At the end of the day, your partner’s preference is the most important factor in choosing a diamond. She will wear this ring for the rest of her life -- you want her to love it.


How Can You Get the Diamond Size You Want While Staying in Budget?

What happens when your partner’s engagement ring preference doesn’t fit into your budget? The good news is that diamond size isn’t the only factor that affects ring price. 

There are four elements to every diamond:

  • Cut 
  • Colour
  • Clarity 
  • Carat

Knowing this, is it possible to sacrifice either cut, colour or clarity so that you can get the carat you want? The short answer is yes.


Round brilliant cut rings are the most popular, also making them the most expensive. Round rings can cost up to 25% more than other cuts such as heart or princess. Round cut diamonds tend to get the more expensive at 1 carat, so if your partner has her heart set on the classic round cut, choosing a size under 1 carat might help keep the price down. 

Additionally, oval and pear cut rings are the next two most popular and expensive rings. Opting for a radiant, princess or emerald cut ring could be the answer to getting your partner the carat size she wants while still staying within budget.


The colour of the diamond has a big impact on how the diamond will look on your partner’s hand. But if size is more important to your partner, then colour can definitely be an area of the diamond where you can cut cost.


Clarity is a “…measurement that notes the number and severity of a diamond’s imperfections, ranging from flawless (FL) to severely included (I3).” Choosing a diamond with a few more imperfections is another way you can cut costs.


It’s All About Personal Preference

The truth is, there is no “best” diamond size. It’s all about your partner’s taste and preference. She’s going to wear that ring for the rest of her life, so it should be a size she’s comfortable having on her hand every day. If you know your partner’s preference and you know your budget, it’s time to go engagement ring shopping.

Now that you’re ready to pick out your partner’s engagement ring, don’t forget to get it insured. Your partner’s special engagement ring deserves the best protection. Contact us for an instant quote and find out why thousands of Australians trust Q Report to insure their engagement rings.
