Halo engagement rings are quite fascinating and one of the most popular options. The halo setting offers an array of customisation options. In this setting, a centre gemstone (or diamond) is encircled by small diamonds. A high-carat centre piece looks stunning in a halo setting.

Cushion cut diamond rings combines square cut and rounded corners and features large facets to create a soft, romantic appeal whilst delivering maximum brilliance. This classic cut creates a distinctive look that will set you apart even in a crowd.

Rose gold rings are a huge trend in Melbourne. Rose gold has become very popular over the past few years. Rose gold has an understated, subtle appeal and has an immensely romantic feel to it that will steal your partner’s heart in style.

Sapphires are graceful, elegant and dazzling, all at the same time. Available in a range of shades from light pink to deep blue, a sapphire engagement ring is a vibrant, distinctive choice. We have sapphire rings in a variety of designs from antique to modern.

Pear shaped rings are sophisticated yet feminine. Combining the elegance of the round brilliant and the classy style of the marquise, the pear cut diamond ring is the epitome of grace and style. We offer pear shaped engagement rings in an eclectic range of designs and styles.

Round engagement rings are the most popular design option. In fact, 75% of all diamond rings sold are round in shape. That goes to show how alluring this cut is. The Diamond Guys bring to you an exciting range of round engagement rings to suit your taste and budget.
An engagement ring should feel personal to the person wearing it. Some customers prefer the simplicity of a solitaire ring, while others want the added sparkle of a halo or diamond-set band.
Popular engagement ring options include:
Your chosen setting can be created in yellow gold, white gold, rose gold or platinum, depending on the design and your preferences.
Customers looking for engagement rings near Melbourne CBD can explore both natural and lab-grown diamond options.
Natural diamonds are formed within the earth over a very long period and remain a traditional choice for engagement jewellery. Lab-grown diamonds are created in controlled environments and have the same basic physical and optical characteristics as natural diamonds.
Each option has different benefits, price considerations and personal appeal. Our team can explain diamond certification, cut, colour, clarity and carat weight so you can compare suitable stones with confidence.
Rather than focusing on size alone, we help you understand how the different diamond characteristics work together to influence beauty, brilliance and value.
A custom engagement ring allows you to create something that is designed specifically for your partner. You may want to adjust an existing ring, combine details from several designs, repurpose an heirloom or begin with a completely new idea.
Our custom design process generally includes:
We discuss your ideas, preferred style, diamond shape, precious metal and budget. Images, sketches or existing jewellery can be used as inspiration.
Once the concept is agreed upon, a computer-aided design is prepared so you can review the ring’s proportions, setting and finer details before production begins.
The ring is cast in the chosen metal, prepared for stone setting, polished and inspected before completion. The standard custom design process generally takes approximately 15–20 business days, although timeframes may vary depending on the design.
You remain involved throughout the process, helping ensure the final ring closely reflects the design you approved.
Buying an engagement ring is a significant decision, and professional advice can make the experience easier. The Diamond Guys provides personalised support from initial diamond selection through to the completed ring.
