1.28 CTS Unheated Natural Mozambique Pigeon’s Blood Ruby | Heart Cut

Pigeon Blood red, with no indication of heat — a 1.28-carat ruby where colour and treatment history carry equal weight.

Gemstone $15,900.00

See this exact gemstone in compatible SARATTI settings.

This 1.28 CTS Natural Mozambique Ruby is distinguished first by a combination of independently documented vivid red colour and the absence of detected heat treatment. GRS identifies the stone as a Natural Ruby of Mozambique origin, records the colour as vivid red, and states “No indication of thermal treatment.” Its appendix further notes that the colour saturation is reminiscent of its GRS-type pigeon blood ruby reference, while specifically noting that the stone does not show strong fluorescence. That qualified laboratory comment is important: it supports the significance of the colour without converting the appendix wording into an unqualified Pigeon Blood designation.

The heart outline gives the Ruby a recognisable, emotionally expressive silhouette while retaining the authority expected of a serious centre stone. GRS records a brilliant/step (4) cut, and the supplied imagery shows the two approaches working together: bright angular reflections define the lobes and perimeter, while deeper red areas through the centre add visual concentration. The cleft is clearly articulated, the point remains defined, and the mixed facet structure allows the vivid red colour to stay dominant rather than being overwhelmed by surface reflection. The face-up appearance also shows enough transparency for the internal facet pattern to remain clearly legible.

At 6.22 × 6.73 × 3.44 mm, the Ruby presents a compact but substantial face-up scale for its 1.28 CTS weight. Its combination of verified Mozambique origin, vivid red laboratory colour, no indication of thermal treatment and carefully resolved heart form gives it appropriate collector-level and high-jewellery relevance. It may be considered as a loose private acquisition or developed through SARATTI as a bespoke centre stone, particularly in platinum or white gold for crisp contrast, with restrained diamond accents if a more formal composition is desired.

Characteristics
  • Significant No-Heat Finding: The independent GRS report records no indication of thermal treatment, an important distinction for a natural Ruby.
  • Treatment: No indication of thermal treatment.
  • Independent Laboratory: Examined and documented by GRS GemResearch Swisslab.
  • Colour: GRS records the Ruby as vivid red. Its appendix states that the colour saturation is reminiscent of “GRS-type pigeon blood ruby,” while noting that the stone is without strong fluorescence. This qualified comment is not presented as an independent Pigeon Blood grade.
  • Origin: Mozambique, as determined by GRS.
  • Weight & Scale: 1.28 CTS, giving the heart-shaped stone meaningful centre-stone presence above the one-carat threshold.
  • Crystal Presentation: The supplied imagery shows a transparent face-up appearance with the mixed facet structure clearly visible through the red body colour.
  • Cut Architecture: Heart shape with GRS-recorded brilliant/step (4) faceting, combining bright perimeter reflections with more concentrated colour toward the centre.
  • Dimensions: 6.22 × 6.73 × 3.44 mm.
  • Collector & High-Jewellery Direction: Appropriate for private loose-gemstone acquisition or an individually engineered SARATTI bespoke centre-stone commission.

Design Invitation

The vivid red colour and defined heart silhouette would create sharp contrast in platinum or white gold, particularly with restrained diamond side stones that allow the Ruby to remain visually dominant.

Why we chose this stone

Pigeon Blood at 1.28-carat.

Consider this ruby if celebrated colour matters as much as treatment history. Pigeon Blood gives it authority; no indication of heat gives you a second, equally meaningful reason to choose it at 1.28-carat.

  • PIGEON BLOOD

Natural ruby ring with an open pavilion so the chromium red returns light | SARATTI Red ruby gemstone hand-set in fine jewellery, seat cut before the metal is finished | SARATTI

HANDCRAFTED

Some reds are worth
building slowly around.

Chromium makes a fine ruby give light back, but only if the setting lets light in. So the pavilion stays open and the seat is cut before the metal is finished. A ring for every day, a pendant kept close, a piece handed on.

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.
