Opal, at a glance.

The effect

Play-of-color.

Precious opal can show shifting flashes of spectral color. Not every opal displays this effect.

The material

Hydrated silica.

Opal’s structure and water content distinguish it from many familiar crystalline gems.

Scratch hardness

About 5 to 6.5.

Opal needs gentle wear and protection from scratches, impact and excessive heat.

The birthstone

An October favorite.

Opal is one of October’s birthstones, alongside tourmaline.

Choose with the whole piece in mind.

See it move.

Ask for video in ordinary light. Look at the color from several angles, not only its brightest photograph.

Know the construction.

Ask whether it is a solid opal, a doublet or triplet, an inlay, or a manufactured material.

Ask about condition.

Check for chips, cracks or crazing and any known treatment. The setting and backing also matter.

Match the piece to your routine.

A pendant may receive fewer knocks than a ring. Choose a design you can wear with appropriate care.

Identity, treatment and documentation.

Opal listings may describe natural solid stones, assembled doublets or triplets, treated material, or manufactured alternatives. Ask which applies, whether any backing or adhesive is present, and what is known about treatments and condition. These details affect both care and comparison.

Ask what is known, what remains unconfirmed, and whether the information is supported by documentation. An independent gemological report can help address identification and detectable treatments. It is different from an appraisal and does not promise a resale value.

Bring these questions to the conversation.

  1. What is known about the material, its origin as natural or laboratory-grown where applicable, and any treatments?
  2. What are the exact dimensions, and does any stated weight describe one stone or the total?
  3. What is the metal, and what is known about the age and condition of the piece?
  4. Can I see additional photos or a video in ordinary lighting?
  5. What fit, fastening, stringing or resizing details should I consider?
  6. What documentation is available for this exact item, and which purchase policies apply?

Include the item number when you contact us. Details from one piece should not be assumed to apply to another.

Care for the entire piece.

Use gentle surface cleaning with lukewarm water and mild soap only when suitable for the exact piece. Avoid ultrasonic and steam cleaners, heat and sudden temperature changes. Do not soak assembled doublets, triplets or glued pieces; ask about their construction before cleaning.

The most delicate material, treatment or construction detail may determine the right method. A gemstone’s scratch hardness does not mean the setting is safe from damage. Check clasps, stringing and prongs regularly, and stop wearing a piece if a stone is loose or a fastening is unreliable.

Make it part of your own style.

Give the light some room.

A pendant against a plain neckline lets shifting color be the detail you notice.

Choose one expressive accent.

An opal ring brings character to a simple outfit. Take it off for work that risks hard knocks.

Pair softly.

Cream, muted blue and warm gold can complement opal without competing with its changing appearance.

October’s birthstone. A color story to give.

For an October birthday or someone who enjoys an unexpected flash of color, opal can be a thoughtful choice. Its appeal begins with the individual piece and the care it deserves.
