What is opal?

Opal is an amorphous silica stone, distinguished by its spectacular play-of-color – a shimmering rainbow of hues that no other gemstone can replicate. No other gemstone looks quite like it.

Opal Types and Value

• Black Opal (Lightning Ridge, Australia): Most intense play-of-color, most expensive opal
• White Opal: Light background – most common type, affordable
• Boulder Opal: Opal embedded in ironstone – full of character
• Fire Opal: Luminous orange, from Mexico – no typical play-of-color

Opal Care: Special Considerations

• Opal contains water (3–21%) – dehydration can lead to cracking
• No ultrasound, no steam, no acids
• Wearing it occasionally helps – body moisture preserves the stone
