Choosing an engagement ring is one of the most exciting parts of planning a proposal, but knowing where to start can feel a little overwhelming.

From diamond shapes and settings to metals and budgets, there's plenty to consider. At Class A, we've helped couples find and create their engagement rings for over 50 years, and we're here to make the process as straightforward and personal as possible.

Whether you're planning a surprise proposal or choosing a ring together, we've put together a guide to help you get started.

WHAT ENGAGEMENT RING STYLE SHOULD YOU CHOOSE?

An engagement ring is something your partner will wear every day, so finding a style that feels like them is a great place to start.

Think about the jewellery they already wear. Do they prefer simple, understated pieces or something a little more distinctive? Are they drawn to yellow gold or white gold? Have they ever mentioned a particular diamond shape?

There are plenty of styles to explore, each with its own character.

• Solitaire: A classic design featuring a single centre diamond. Timeless, simple and designed to let the diamond take centre stage.

• Trilogy: Three stones, traditionally representing your past, present and future together.

• Halo: A centre diamond surrounded by smaller diamonds, adding extra sparkle and presence.

• Toi et Moi: Two stones set alongside one another, symbolising two people coming together.

• Bezel: A modern setting where a fine rim of metal surrounds the diamond, offering a sleek finish and added protection.

If you're unsure, our Signature Engagement Ring Collection is a great place to explore different styles and find inspiration.

WHICH DIAMOND OR GEMSTONE IS RIGHT FOR YOU?

The centre stone is often the starting point when designing an engagement ring.

Diamonds remain a popular choice thanks to their brilliance, durability and timeless appeal. When choosing a diamond, there are four key characteristics to understand, known as the 4Cs:

• Cut: How well the diamond has been cut and how it reflects light.

• Colour: How colourless a white diamond appears.

• Clarity: The presence of natural inclusions or internal characteristics.

• Carat: The weight of the diamond, which influences its overall size.

Diamond shape is another important consideration. From classic round brilliant and oval diamonds to pear, emerald, marquise and elongated cushion cuts, each shape offers a different look on the hand.

Natural or lab grown diamonds?

Both are real diamonds, sharing the same physical, chemical and optical properties. The main differences are how they're formed, their rarity and their price.

Natural diamonds are formed deep within the earth over billions of years, while lab grown diamonds are created using advanced technology in a controlled environment.

Lab grown diamonds are generally more affordable, making them a popular choice for couples wanting a larger carat weight within their budget.

What about coloured gemstones?

If you're looking for something a little different, coloured gemstones can bring a personal touch to an engagement ring.

Sapphires are a popular choice, available in a range of colours beyond traditional blue. Other gemstones, such as aquamarine and tourmaline, offer distinctive colours, although they require different levels of care compared with diamonds.

Our team can help you explore gemstone options and find something suited to your design and lifestyle.

WHICH PRECIOUS METAL SHOULD YOU CHOOSE?

The metal you choose plays a big part in the overall look of your engagement ring.

At Class A, we work with a range of precious metals, including:

• Yellow Gold: A timeless choice with a warm, rich colour. Available in 18ct gold.

• White Gold: A bright, silvery finish that complements white diamonds. White gold is typically rhodium plated and may require re-plating over time to maintain its bright white appearance.

• Rose Gold: A soft, warm pink tone that offers a slightly different take on traditional gold.

• Platinum: A naturally white, durable precious metal that doesn't require rhodium plating. Its surface can develop a patina with everyday wear.

When deciding, consider the jewellery your partner already wears and whether they'd prefer their engagement ring to match.

If you're unsure, trying on different metals in person can make the decision much easier.

SHOULD YOU CHOOSE READY TO WEAR, MADE TO ORDER OR BESPOKE?

Every proposal is different, and so is the process of finding the right ring.

At Class A, we offer three ways to find your engagement ring.

Ready to Wear Engagement Rings

Planning to propose soon? Our ready to wear engagement rings are available for immediate purchase, with a selection of our most popular designs and diamond shapes.

Each ready to wear engagement ring also includes complimentary resizing, so you don't need to know the exact finger size before purchasing.

Made to Order Engagement Rings

Our Signature Engagement Ring Collection can be made to order in your preferred precious metal, diamond shape and specifications.

Each ring is crafted in our Adelaide workshop, with a typical manufacturing timeframe of approximately 4–6 weeks.

Bespoke Engagement Rings

If you have a particular design in mind, our bespoke service allows you to create something entirely your own.

From choosing the centre diamond to refining the setting, band proportions and finer details, you'll work with our team to bring your ideas to life.

Whether you're starting with a reference image or an idea you've had for years, we'll guide you through the design process.

WHAT IF YOU DON'T KNOW THEIR RING SIZE?

If you're planning a surprise proposal, finding out your partner's ring size can be one of the trickier parts.

If they already wear rings, you may be able to borrow one to have it measured, provided it's worn on the correct finger. Otherwise, a close friend or family member might be able to help.

And if you're still unsure, don't let it hold up your proposal.

Our ready to wear engagement rings include complimentary resizing within 12 months of purchase, so you can choose the ring first and arrange the perfect fit afterwards.
