How do I choose an engagement ring?

Start by getting familiar with the 4Cs: cut, colour, clarity and carat weight, along with the different diamond shapes and styles available. Then look at the jewellery your partner already wears. Their preferred metal, whether they favour classic or contemporary pieces, and how bold or minimal their style is can all help narrow down the right ring.

How much should I spend on an engagement ring?

There is no “right” amount to spend on an engagement ring, and the old salary rule is outdated. Your budget should reflect your own circumstances and what feels comfortable. At GS Diamonds, engagement rings range from a few thousand dollars to much higher-value designs, with consultants available to help you balance the metal, setting, diamond size and overall style.

Can you buy an engagement ring on a payment plan?

At GS Diamonds, you can buy an engagement ring on a flexible payment plan, making it easier to manage your budget while still choosing the perfect ring. Learn more about our available payment options.

Is it safe to buy diamond rings online?

Yes, provided you buy from a trusted jeweller and can verify the stone and purchase conditions. At GS Diamonds, natural diamonds come with GIA certification and lab grown diamonds with IGI certification. Secure payment options and insured delivery also provide additional reassurance when purchasing diamond rings online.

How many carats should an engagement ring be?

There is no ideal carat weight for every engagement ring. The right size depends on your budget, preferred diamond shape, finger size and the setting. Carat measures weight rather than visible dimensions, so an oval or marquise diamond may appear larger than a round diamond of the same carat weight.

What are the different styles of engagement rings?

Popular engagement ring styles include solitaire, halo, three-stone, side-stone and pavé designs. The setting changes how the centre stone looks and how much sparkle the ring has. Solitaire styles feel clean and classic, while halos and side stones add more detail. Custom designs can combine different elements to create something more individual.

Does an engagement ring have to be a diamond?

No. Diamonds are the traditional choice because of their durability and brilliance, but gemstone engagement rings are also a beautiful option. Sapphire, ruby, emerald and aquamarine can bring colour and personality to the design. The most important consideration is choosing a stone that suits the wearer’s style and lifestyle.

Can men wear engagement rings?

Yes. Men can absolutely wear engagement rings, and more couples are choosing rings for both partners. Men’s designs can range from simple diamond-set bands to more distinctive custom styles, depending on personal taste. There is no rule about who should wear an engagement ring or what that ring needs to look like.

Measure your ring size

Planning a proposal or buying a ring for yourself? Here are five reliable ways to measure ring size.

How to measure your ring size

Find your size

Measure a Ring That Already Fits

Place the ring on a flat surface or ruler.
Measure straight across the centre of the inside circle
Measure in millimetres
Compare the diameter with a ring size chart.
Make sure the ring is worn on the same finger the new ring is for.

Use a Plastic Ring Sizer Tool

Slide the sizer onto your finger.
Tighten it until it feels snug but comfortable.
Make sure it slides over the knuckle with slight resistance.
Check it sits securely at the base without spinning.
Read the indicated size on the tool.

String or Paper Strip Method

Wrap a string or paper strip around the base of your finger.
Mark where the ends meet.
Lay it flat and measure the length in millimetres.
Compare the measurement with a ring size chart.
Avoid pulling too tight — this method is a rough estimate only.

Printable Ring Size Chart

Print the ring size chart at 100% scale.
Place your ring over the printed circles.
Find the circle that fits perfectly inside the band.
Ensure there are no gaps or overlaps.
Use a ring worn on the correct finger for accuracy.

Most asked questions

Find an Engagement Ring Made for Your Story

Choosing an engagement ring starts with finding the right balance of diamond, design and personal style. At GS Diamonds, natural diamonds come with a GIA grading report, while lab grown diamonds are IGI certified, giving you independent information about the quality and origin of the stone before you buy.

If you are comparing engagement ring styles, start with the overall look you love. For example, a solitaire engagement ring keeps the focus on the centre stone, while a halo design adds extra sparkle and presence.

You can also explore lab grown diamond engagement rings or men's engagement rings for more dedicated options.

At GS Diamonds we have helped couples choose diamond engagement rings through our boutiques in Sydney, Brisbane, Melbourne and Perth, as well as through our Australia-wide online service. Our 5-star reviews reflect the care and guidance we provide at every step, and we offer free shipping Australia-wide on all orders along with a 30-day money-back guarantee. If you are comparing stones, our guide to the 4Cs and certified vs non-certified diamonds can help you understand what you are buying.

For something entirely personal, you can design your own engagement ring with the help of our team. The custom process typically takes around 4-8 weeks, including design, production and final quality checks, with detailed 3D renders helping you visualise the finished piece before it is made.
