Opal Birthstone Jewellery At A Glance

October Birthstone Jewellery Styles

Opal birthstone jewellery comes in four main styles. Here's how each one wears, so you can choose the right piece.

Opal Rings: A personal, meaningful gift, but you'll need her ring size. Rings take more knocks than other jewellery, so bezel settings can be preferred as they are more protective.

Opal Pendants: An opal birthstone necklace or pendant is the easiest opal gift to get right, with no sizing to guess. A pendant sits away from everyday knocks, so it's ideal for wearing often. Our pendants come with a complimentary display chain. For everyday wear, choose a sterling silver or gold chain to match your pendant, or wear it on one of your own.

Opal Earrings: Worn close to the face, where the colour is easy to see. Studs suit everyday wear, while drop earrings move with you and show more changing colour.

Opal Bracelets: A lovely choice for special occasions. Because bracelets can knock against tables and desks, make sure you wear with care and take the bracelet off for the gym, gardening and housework.

Browse by style: Opal rings, Opal pendants, Opal earrings and Opal bracelets.

Types Of Opal In Our Birthstone Jewellery

• Black opal: Has a dark body tone that makes the colours look bold and vivid. Mined mainly at Lightning Ridge, it's the rarest type.
• Crystal opal: Is transparent to translucent, with bright colour that seems to radiate from within.
• White opal: Has a milky body tone with soft, gentle colour, and is a lovely, affordable choice.
• Boulder opal: Forms naturally on ironstone in Queensland, often in organic, freeform shapes.
• Doublet: A slice of genuine opal backed with a dark layer to bring out the colour. It gives more colour for the price.
• Triplet: A layer of genuine opal with a dark backing and a clear protective cap. It's the most affordable way to enjoy bright opal colour.

How To Buy Opal Birthstone Jewellery

When buying jewelry set with opal, it’s important to look for:

• Colour: Look for bright flashes that move as you tilt the stone. Red is the rarest colour, with blue and green the most common.
• Setting: Bezel settings protect the edges of the opal stone, which is ideal for rings worn every day.
• Metal: Sterling silver suits everyday wear and smaller budgets, gold plated silver gives a gold look at a lower price, and gold is made to last for years.

October Birthstone Jewellery FAQs

What is the birthstone for October?

Opal is an October birthstone, alongside tourmaline. Opal is the traditional choice, and most of the world's gem-quality opal comes from Australia.

Is opal a good birthday gift?

Yes. No two opals are the same, so every piece is one of a kind. It's a gift that feels personal, especially for someone born in October.

Why is Australian opal considered the best?

Australian opal is widely regarded as the finest quality opal in the world due to its intense colour play and natural formation. Australia produces the majority of the world’s precious opal.

Can opal be worn every day?

Yes, with a little care. Opal is softer than sapphire or diamond, so protective settings help, and it's best to take it off for the gym, gardening or cleaning. Solid opals can get wet, but doublets and triplets should be kept out of water. Read more about opal care in our guide.

5. What type of opal is best for birthstone jewellery?

The most desirable opals for birthstone jewellery are black opal from Lightning Ridge, crystal and white opal from Coober Pedy, and boulder opal from Queensland. Each type offers different colour intensity, body tone and appearance.

What is the best opal jewellery to gift for birthdays?

All types of opal jewellery are suitable to gift those born in October, especially pendants and earrings which don't typically require special sizes. Opal rings are also a popular choice due to their symbolism, and bracelets make impressive presents too.

Is opal a lucky birthstone?

Opal has long been seen as a stone of luck, love and inspiration. In many cultures it was believed to bring good fortune, creativity and emotional balance to the wearer. Because opal reflects many colours, it was thought to carry the powers of multiple gemstones in one stone. Read more about opal's bad luck myth.

Are doublets and triplets real opal?

Doublets and triplets are composite stones. Each contains a layer of genuine Australian opal joined to a backing to bring out the colour. Triplets also have a clear quartz cap for extra protection. They're a great choice if you'd like bright colour at a lower price.

Will my gift come with a certificate?
