Opal Earrings Natural Diamonds in 18kt Yellow Gold

These earrings are truly one of a kind. While most gemstone studs offer a simple pop of colour, these opal earrings take it to the next level with their sculpted teardrop shape, vibrant natural opals, and a halo of dazzling natural diamonds. The warm tone of 18kt yellow gold enhances the opal’s green and blue fire, adding a rich contrast that white gold can’t quite deliver. They’re bold but balanced, classic yet distinctive — perfect for the modern woman who loves timeless jewellery with a twist.

Absolutely. All Ernesto Buono diamonds are 100% natural and sourced through ethical, conflict-free suppliers who meet international standards, including the Kimberley Process. These earrings feature 28 round brilliant diamonds, each selected for their F colour and VS clarity, ensuring exceptional sparkle and long-term value. When you choose Ernesto Buono, you’re not just investing in luxury — you’re supporting responsible craftsmanship and sustainability in the jewellery industry.

You can absolutely wear them every day — with care. Opals are slightly softer than diamonds or sapphires, so it’s best to avoid exposure to harsh chemicals or impact. That said, these earrings are set securely in a protective yellow gold bezel with butterfly backs for added stability. They’re lightweight, comfortable, and add just the right amount of colour and sparkle to casual or professional looks. For special occasions, they also shine brilliantly — literally and figuratively.

Opal is more than just a beautiful gemstone — it’s a stone of emotion, inspiration, and creativity. Believed to amplify individuality and inner strength, it’s often given as a symbol of loyalty, intuition, and joy. As the birthstone for October, it makes an especially meaningful birthday gift, but its colour-shifting brilliance makes it a cherished keepsake year-round. When paired with diamonds, opals take on a new dimension — combining soft organic beauty with the clarity and brilliance of the world’s hardest gemstone.

To maintain their brilliance, clean your earrings with warm water, mild soap, and a soft cloth or brush. Avoid soaking them, especially in harsh solutions or ultrasonic cleaners, as opals are sensitive to moisture and temperature changes. After cleaning, pat dry and store in a soft pouch or lined box, away from other hard jewellery. Need professional maintenance or advice?
