Diamonds may have the ‘girl’s best friend’ tag, but a glimmering opal engagement ring is a gorgeous eye-catching alternative. You might choose to combine it with classic diamonds in a traditional engagement ring setting or showcase the stone alone in all of its prismatic glory – no matter what ring you choose, opal is a mesmerising gem choice that’ll never look dull. 

Whether you’re in the market for a precious white opal, a coloured opal, or a rare black opal, there’s a style to suit every modern nearly-wed. Like any gemstone, each opal is completely unique but many opals offer even more variety. The most popular form of opal has a semi-transparent white base with a milky appearance and hues of blue, green, or pink running through it, depending on the stone. Coloured opals can range in shade from pastel pink to deep red and orange (known as fire opals), while black opals are the rarest of all, with a black base colour and often vibrant flecks of colour. 

All in all, opal makes for an engagement ring so special that it glows, plus it’ll appear different depending on the light and time of day. For a forever piece of jewellery, it’s a gemstone that’s as versatile as it is valuable. Browse our edit of the best opal engagement rings below to find ‘the one’.
