Rather than a long introduction, here are the questions people usually ask about a stone like this 1.75 carat Australian opal.

Where is it from, and does it matter?

It is listed as Australian, the country most closely linked with opal. Origin helps you place a stone, but it never replaces looking at the colour play with your own eyes.

How do I ask about it?

Quote AG-000605 on WhatsApp. We can send photos or a short video, and answer anything else you want to know before ordering.

Is it treated?

Whole opal is generally sold natural, but smoked and sugar-darkened stones exist, along with doublets and triplets. We sell solid natural opal and will tell you what we know about this particular stone. Independent lab testing is your choice, and you are welcome to arrange it.

How should I wear it?

It is a natural fire opal with play of colour and a hardness of 5.5 to 6.5 on the Mohs scale. A pendant is the kindest setting. A ring should be worn with care and taken off for heavy work. Keep it away from heat.
