Its vivid cushion-cut ruby centre is framed by rich red side rubies, while brilliant-cut natural diamonds add sparkle from every angle. Crafted for those who want their jewellery to be unforgettable, this piece isn’t just beautiful—it’s empowering.

    Whether you’re celebrating love, success, or simply your own style, this ring adds fire and grace to any moment.

    Why This Ruby and Diamond Ring Deserves a Spot in Your Collection

    • Gemstone:

    At the heart of this ring sits a cushion-cut ruby, vibrant and full of character. Four additional rubies encircle the centre, deepening the colour and drama.

    • Accent Stones:

    Each ruby is surrounded by natural diamonds, arranged in sparkling clusters that mimic floral petals. These stones catch the light beautifully, creating a dazzling contrast.

    • Metal:

    Set in 18kt white gold, the cool-toned metal makes the rubies appear richer and the diamonds shine brighter. Plus, it offers strength and luxury in equal measure.

    How to Style This Ring with Other Ernesto Buono Favourites

    Want to create a complete look? Pair this ring with a ruby and diamond pendant to highlight its warmth. Or try a diamond tennis bracelet for extra sparkle. If you prefer colourful contrast, go bold with our oval sapphire rings. These pieces balance modern charm with timeless design.

    What Makes This Ring Unforgettable?

    This ruby and diamond ring is for women who want more than sparkle—they want meaning. Rubies symbolise courage and love, while diamonds stand for forever. Put them together and you’ve got a piece that says, “I’ve arrived.”

    Each gem is chosen for colour and brilliance, and every detail is handcrafted for perfection. Our Sydney clients love it because it speaks their language—elegant, bold, and distinctly modern.

    FAQs About Ruby and Diamond Rings

    How should I care for a ruby and diamond ring?

    Caring for this ring is straightforward but important. Rubies are tough (Mohs hardness of 9), and diamonds are the hardest gemstone of all. But the precious white gold and intricate settings still deserve some TLC. Avoid exposing your ring to household chemicals (think bleach, ammonia, even some detergents). When cleaning, use a mild soap solution and a soft brush. Store it separately in a pouch or box to prevent scratches. And pop into our Sydney boutique once a year for a professional clean and check — it’s the best way to keep it sparkling for generations.

    Can I wear my ruby and diamond ring every day?

    Absolutely! This ruby and diamond ring is designed for everyday luxury. Thanks to the toughness of rubies and diamonds, it stands up well to daily life. Still, remove it before heavy lifting, gardening, or gym workouts to protect the settings. Many of our clients wear theirs daily as a statement of their personal style. It’s jewellery meant to be lived in, not hidden away.

    What makes Ernesto Buono’s ruby and diamond rings different?

    It all comes down to detail. At Ernesto Buono, we obsess over sourcing vivid rubies with exceptional clarity, pairing them with natural diamonds for unmatched brilliance. Each ring is carefully crafted by master jewellers who focus on balance, proportion, and enduring strength. That means when you choose our ruby and diamond ring, you’re not just buying a piece of jewellery — you’re investing in artistry and a small slice of luxury made just for you.

    Is it possible to customise this ruby and diamond design?

    Definitely. Whether you’d like a different ruby size, more or fewer diamond clusters, or even to explore this design in rose or yellow gold, we can create a bespoke ring that matches your personal vision. Our team loves collaborating to design one-of-a-kind pieces. Book a consult through our appointment page to bring your dream ring to life.

    Why is white gold chosen for this design?

    White gold is a brilliant backdrop for rubies and diamonds. Its cool tone makes the red pop and intensifies the diamonds’ sparkle, creating an elegant, sophisticated contrast. 18kt gold offers the perfect blend of purity and strength, meaning your ring stays luxurious while standing up to everyday wear. It’s a choice that balances beauty with practicality.
