Play-of-colour across 3.94-carat — an opal that changes with movement rather than giving everything away at first glance.

See this exact gemstone in compatible SARATTI settings.

This natural Ethiopian Black Opal displays a dark blackish-red bodycolour with strong visible play-of-colour across its pear-shaped form. Red and orange dominate the surface, while smaller areas of green and subtle blue appear through the darker ground, creating vivid contrast and depth.

Fashioned as a pear cabochon, the gemstone presents a smooth domed surface, a rounded lower end and a tapering point that gives the outline a graceful vertical profile. Its polished finish allows the shifting colour to move across the face of the stone, while the darker body tone supports the visibility of the brighter flashes.

Weighing 3.94 carats and measuring 14.2 × 10.1 mm, this Black Opal is suited to a protective pendant, drop-style jewel or carefully supported bespoke ring. The dark bodycolour has been produced or enhanced through smoke treatment, disclosed in the gemstone details.

Characteristics
  • A natural Black Opal distinguished by its dark blackish-red bodycolour and visible play-of-colour.
  • Red and orange flashes appear most prominently, with green and subtle blue visible in smaller areas.
  • The gemstone has a pear outline that creates an elegant elongated silhouette.

  • Measuring 14.2 × 10.1 mm, its proportions suit a pendant or other vertically oriented jewellery format.
  • The stated origin of the Black Opal is Ethiopia.
  • Visible play-of-colour includes red, orange, green and subtle blue across different areas of the gemstone.
  • The Black Opal has been smoked, disclosed transparently in the gemstone details.

  • Accompanied by a SARATTI Gemstone Identification Report.

The case for this opal is specific: play-of-colour paired with black. Together, those qualities give you a clearer reason to choose this stone than carat weight or shape alone.

HANDCRAFTED

Never twice the same,
and never quite still.

Several percent water and no internal structure, so it is set cold and shielded at the girdle. Its color has a best direction, found by turning it. A pendant that shifts as you walk, earrings that flash, a ring for kind hands.

Before you decide

Questions worth asking.

Is this the exact gemstone I will receive — and can I see more of it?

Yes. The gemstone shown on this page is the individual stone you are considering — not a representative image from a parcel.

We photograph and film the actual stone and do everything possible to show its color, proportions and character faithfully. Even so, gemstones can respond differently to daylight, warm interior light and different screens.

If you are uncertain, we can provide additional photographs or video and, where useful, reshoot the stone under different lighting or from another angle before you decide.

Can I confirm the gemstone is still available before I proceed?

Of course.

Send us the product link or reference and our concierge can confirm availability before you proceed.

For an important purchase, we would rather confirm first than have you make a decision around a stone that has already been spoken for.

How do I know which setting will suit this gemstone?

The builder presents settings intended to work with the gemstone you have selected.

Before production begins, the pairing is reviewed for proportion, security and suitability.

If we believe another setting, proportion or approach would serve the stone better, we will tell you before anything is made. The setting should serve the gemstone — not simply accommodate it.

What happens after I choose my gemstone and setting?

We confirm the important details with you before production begins.

That includes your gemstone, setting, metal, side stones where relevant, size, engraving and any personal details.

Nothing enters production until the final specification has been reviewed and approved.

Will I see the finished piece before it is sent?

Yes.

Once your piece is complete, it is photographed and filmed with your gemstone set into it.

Those images are sent to you before dispatch, so you can see the finished jewel before it leaves SARATTI.

How long will my piece take?

Made-to-order pieces generally require around three to four weeks from final approval to completion.

A loose gemstone purchased on its own can usually be prepared for dispatch much sooner.

If you are working towards a proposal, anniversary, birthday or travel date, tell us before ordering. We will let you know what is realistically possible rather than promise a date we cannot honour.

How will my order be delivered?

Your order is sent by insured courier with tracking and appropriate delivery security.

The route and carrier depend on destination and value.

Where duties or local taxes may apply, our concierge can explain the available delivery options before dispatch.

Can I return a loose gemstone?

A loose gemstone may be returned within fourteen days of delivery provided it remains unworn, unset and unaltered, with its packaging and documentation intact.

Please contact us before sending anything back so the return can be arranged securely.

What happens once the gemstone has been set?

A jewel created around your selected gemstone is made specifically for you.

Once the final specification has been approved and production has begun, the gemstone and materials are committed to your piece.

That is why we take time to confirm the details with you before making begins.

What if I am still unsure?

Then do not rush the decision.

We can help you compare this gemstone with another, look again at color or proportion, send additional imagery, discuss a setting or simply talk through what matters most to you.

The right stone should feel considered — not hurried.

What happens after I receive my piece?

Our relationship does not end at delivery.

SARATTI provides ongoing care for the jewelry we create, including inspection, cleaning and appropriate maintenance support as the piece is worn over time.

If anything ever concerns you, speak with us before attempting repair or alteration elsewhere.
