What Makes an Engagement Ring Special?
An engagement ring is more than jewellery, it symbolises commitment, love, and a shared future. The right ring should reflect both personal style and the meaning behind the moment.
At Ernesto Buono Fine Jewellery, we create:
Custom Engagement Rings- Natural Diamond Engagement Rings
- Lab Grown Diamond Engagement Rings
- Coloured Gemstone Engagement Rings
Custom Engagement RingsEvery design is created with a focus on beauty, longevity, and wearability
Solitaire Engagement Rings
Solitaire engagement rings are timeless and elegant, designed to showcase the centre stone with minimal distraction. This classic setting remains one of the most popular engagement ring styles in Australia.
Hidden Halo Engagement Rings
A hidden halo adds extra brilliance beneath the centre diamond while maintaining a clean and sophisticated appearance from above.
Three Stone Engagement Rings
Three stone engagement rings symbolise the past, present, and future. They offer additional sparkle and a balanced, luxurious design.
Vintage Inspired Engagement Rings
Vintage-inspired designs feature intricate detailing, milgrain edges, and romantic craftsmanship influenced by antique jewellery styles.
Custom Engagement Rings
We also specialise in custom engagement rings, allowing you to create a one-of-a-kind piece by choosing your preferred diamond shape, setting style, metal, and diamond size. Book an appointment to discuss your engagement ring ideas or create a custom design tailored to you.
Engagement Ring Prices
Our engagement rings start from $3,890, with most clients spending between [$5,000 and $10,000]. Price depends on four things: the diamond’s carat, cut, colour and clarity; natural versus lab grown; the metal; and the setting’s detail.
Lab grown diamonds typically cost far less than natural diamonds of the same size and grade, so many couples choose a larger lab grown stone for the same budget. Tell us your budget at your consultation and we’ll show you the best options within it, without pressure.
Choosing Your Metal
We make engagement rings in 18ct yellow gold, 18ct white gold, 18ct rose gold and platinum.
We pair your engagement ring with a matching wedding band, made to sit flush or curved around your setting.
Understanding the 4Cs
Cut
How well the diamond reflects light. It matters most for sparkle.
Colour
Graded D (colourless) to Z. [G–H] looks white to most eyes in a yellow gold setting.
Clarity
Natural inclusions. Eye-clean [VS2–SI1] stones give the best value.
Carat
Weight, not size. Ovals and pears look larger per carat than rounds.

Natural vs Lab Grown Diamonds
What Is the Difference?
Natural diamonds are formed within the earth over billions of years, while lab grown diamonds are created using advanced technology in controlled laboratory environments.
Both options are:
- Real diamonds
- Chemically identical
- Equally brilliant in appearance
The difference comes down to:
- Origin
- Budget
- Personal preference
- Sustainability considerations
Budget 
Natural vs Lab Grown
Both natural and lab grown diamonds can be graded by independent labs such as GIA and IGI, so you know exactly what you’re buying. Natural diamonds hold their rarity and traditional appeal. Lab grown diamonds give you more size and quality for your budget. Our diamond specialist can show you both side by side in our Sydney showroom.
Coloured Gemstone Engagement Rings
For couples drawn to something more distinctive, coloured gemstone engagement rings offer a more personal expression of style. From the depth of blue sapphires and London blue topaz to the soft tones of morganite and aquamarine, each gemstone brings its own character. Rich emeralds, opals, rubies, champagne diamonds, yellow diamonds, and amethyst designs create engagement rings that feel both timeless and individual.
