Question 1

What is opal?

Accepted Answer

Opal is a natural gemstone formed over millions of years as silica-rich water slowly deposits layers of material in cracks and cavities in rock. What makes opal special is its ability to display flashes of colour when light hits the stone. As the stone moves, the colours shift and change, creating the beautiful effect opals are known for.

Question 2

Are your opals natural?

Accepted Answer

Yes. All opals used in jewellery by Jack the Jeweller are natural gemstones. If a stone has received any industry-standard treatment, or if a composite stone such as a doublet or triplet is used, this will always be clearly explained.

Question 3

What types of opal do you work with?

Accepted Answer

Most jewellery features Australian opal, including black opal from Lightning Ridge, crystal opal, white opal, and boulder opal. These stones are known for their stability and vibrant colour. Other gemstones such as sapphire, ruby, emerald, and diamonds may also be used depending on the design.

Question 4

Why are opals so unique?

Accepted Answer

Every opal forms under slightly different conditions in nature. Because of this, no two stones ever display the same play-of-colour and brightness. The patterns, colours, and intensity of the light inside the stone are completely individual, which means every opal jewellery piece is truly one of a kind.

Question 5

Can I choose my own stone?

Accepted Answer

Yes. Many clients choose the exact stone that will go into their jewellery. Because every opal is unique, selecting your own stone allows you to find the colour pattern and brightness that you personally connect with.

Question 6

Can opals get wet?

Accepted Answer

Yes. Australian sedimentary opals are very stable gemstones. They have a stable chemical structure and are non-porous, meaning water or other liquids cannot enter the stone or change its structure. Because of this, Australian opals can safely be washed with water and mild soap.

Question 7

How should opal jewellery be stored?

Accepted Answer

It’s best to store opal jewellery separately from harder gemstones such as diamonds or sapphires that could scratch the surface. A soft pouch or lined jewellery box works well.

Question 8

How do I know the opal is genuine?

Accepted Answer

All gemstones used by Jack the Jeweller are carefully sourced and inspected before being used in jewellery. Where possible, stones are purchased directly from reputable Australian suppliers and miners.
If a stone is a composite such as a doublet or triplet, this will always be clearly disclosed.

Question 9

Why do some opals cost more than others?

Accepted Answer

The value of an opal depends on several factors including:
• brightness of the play-of-colour

• colour intensity and rarity

• pattern

• body tone

• size and shape

• overall quality of the stone

Question 10

Is Australian opal better than Ethiopian opal?

Accepted Answer

Australian sedimentary opals are generally considered the most stable and durable opals for jewellery. They have a stable chemical structure and are non-porous, which means liquids cannot enter the stone.
Ethiopian opal is often hydrophane, meaning it can absorb water or oils. When this happens the appearance of the stone can temporarily change.
Because of this difference, Australian opal is usually preferred for long-term jewellery.

Question 11

Is opal a good choice for engagement rings?

Accepted Answer

Yes. Many people choose opal for engagement rings because of its unique colour and individuality.
Like any gemstone other than diamond or sapphire, it should be set in a protective design and worn with reasonable care. With a well-designed setting and normal care, opal can make a beautiful and meaningful engagement ring.

Question 12

Is each opal truly one of a kind?

Accepted Answer

Yes. No two opals ever display the same play-of-colour and brightness. This means every opal jewellery piece is completely unique.
When you own an opal, you are wearing something that nature created only once.
