What is Opal?

Opal is an amorphous gemstone that produces a rainbow of colours that span the entire colour spectrum, unlike most gemstones. There are many types of opals, including black opal, fire opal, and white opal, each with unique properties.

Colourful History of Opal

Their name derives from the ancient Greek and Latin words ‘opallios’ and ‘opalus’, meaning ‘to perceive a colour change.’ Opal gemstones have been cherished as symbols of hope, creativity and emotional depth since ancient times.

Opal Folklore And Myths

Opals have inspired wonder and storytelling for centuries, earning a place in the myths and legends of numerous cultures worldwide. The ancient Romans prized opals above all other gemstones, believing they held the power of every other gem due to their shifting colours.

In Arabian folklore, opals were said to fall from the sky in bolts of lightning. This belief helped shape the mystical reputation of the opal, linking it to the heavens and elements of divine energy. Similarly, ancient Greeks thought opals gave their owners the gift of prophecy and protected them from disease. In India, opals were considered sacred and linked to the goddess of the rainbow, who transformed herself into the gem to escape the advances of the gods.

Factors to Consider When Buying Opal Jewellery

With their ever-changing hues and dreamy glow, opals are unlike any other gemstone. The obvious question is- how to buy opal jewellery?

1. ​Determine the type of opal

Is it a black opal, white opal, crystal opal, etc.?

• Black Opal – Features a dark body tone with vibrant flashes of colour.
• White Opal – Has a light or milky body tone
• Fire Opal – Known for its warm orange, yellow, or red body colour
• Crystal Opal – Transparent to semi-transparent with bright, vivid colour flashes

2. Determine the Opal’s Transparency

An opal’s transparency plays a major role in its appearance, beauty, and value. To identify an opal correctly, observe how much light passes through the stone when held under natural or bright light.

• Transparent – Light passes clearly through the opal
• Semi-Transparent – Allows some light to pass through
• Opaque – Does not allow light to pass through. Black opals and many white opals are commonly opaque.

3. Determining Through Touch

Real opals tend to be cool to the touch due to their water content and natural formation process. In contrast, many synthetic or lab-made opals can feel warmer or even plasticky.

4. Price

Price is another sign of authenticity. Genuine opals, especially black and fire opals, are not cheap

Popular Opal Jewellery Types

From ethereal rings to luminous pendants, opal jewellery comes in styles as unique as the gems themselves.

1. Opal Rings

Known for their spellbinding play of colour, opal rings make for stunning and meaningful gifts. Opal engagement rings make for a more romantic and distinctive choice than traditional diamond rings.

2. Opal Necklaces

Opal necklaces and pendants beautifully highlight the gemstone’s vibrant flashes of colour. 

3. Opal Bracelets

Opal bracelets offer a soft, iridescent shimmer that’s both enchanting and elegant.

4. Opal Earrings

Opal earrings are incredibly versatile and catch the light with every movement of the head.

How to Style Opal Jewellery

• Daytime Looks

For an effortless daytime style, pair a dainty opal pendant or simple opal stud earrings with neutral outfits.

• Evening Looks

For a bold and glamorous evening look, choose statement black opal or fire opal earrings paired with sleek dresses or darker tones.

• Layering Opal Jewellery

Layer delicate opal necklaces with gold or silver chains of varying lengths for a modern, trendy look.

How to Clean Opal Jewellery Without Damaging It

Because opals contain water and are relatively soft compared to other gemstones, they require a little extra care to maintain their beauty. Proper storage and gentle cleaning will help preserve their colour, clarity, and unique play-of-colour for years to come.

• Avoid Harsh Environments: Never expose opals to extreme heat, drastic temperature changes, or harsh chemicals.
• Cleaning: Use only a soft cloth and mild, soapy water. Never use ultrasonic cleaners, steam, or boiling water.
• Storage: Store separately in a soft pouch to avoid scratching from harder gemstones like diamond.

Frequently Asked Questions About Opal Stones

• What is an opal stone made of?

Opal is composed of hydrated silica, a natural mineral formed from a mixture of silicon dioxide and water. Its unique internal structure reflects and diffracts light, creating the “play-of-colour” effect that makes opals so distinctive.

• Is opal a precious gemstone?

Opal is generally classified as a semi-precious gemstone. However, rare varieties such as black opals can be highly valuable due to their intense colour play, rarity, and demand in the jewellery market.

• How do you style opal gemstone jewellery?

Opal jewellery looks best when styled as the focal point of your outfit. Pair delicate opal pendants, rings, or earrings with neutral tones and minimal accessories to let the gemstone’s vibrant colours stand out beautifully.

• Is opal jewellery suitable for daily wear?

Opals are softer than many gemstones, with a Mohs hardness of around 5.5 to 6.5. While opal jewellery can be worn regularly, it requires gentle handling and proper care to avoid scratches, impact damage, or prolonged exposure to water and chemicals.

• Do opals bring good luck?

Throughout history, opals have been associated with love, hope, creativity, and good fortune. Many cultures believed opals carried protective and mystical energies, making them symbols of inspiration and positivity.
