1.01 CTS Unheated Natural Mozambique Pigeon's Blood Ruby | Heart Cut

A compact unheated heart ruby with concentrated red color.

Gemstone $11,100.00

Your gemstone is set into the design you choose. Every pairing is reviewed by a SARATTI specialist before production begins.

The distinction of this 1.01 CTS Natural Mozambique Ruby lies in the relationship between its concentrated red color, heart-shaped outline, and independently documented absence of thermal treatment. GRS identifies its color as vivid to deep red, a description reflected in the gemstone's rich central tone and brighter red reflections around its perimeter. Its accompanying laboratory appendix notes that the color saturation is reminiscent of GRS-type pigeon blood ruby, without strong fluorescence. This carefully qualified observation adds important context to the gemstone's color character, while the confirmed no-heat finding gives it particular significance among natural rubies of comparable size.

The heart-shaped outline presents rounded upper lobes, a defined central cleft, and a tapered lower point, giving the gemstone a recognizable silhouette despite its relatively compact dimensions. Its brilliant/step (5) faceting creates an interplay between the deeper red central area and smaller, brighter reflections along the surrounding facets. In the supplied photographs, the central portion appears noticeably darker than the illuminated edges, producing a contrast that emphasizes the depth of its color rather than an entirely uniform face-up brightness. This combination of concentrated saturation and angular reflections gives the ruby a distinctive visual character.

Weighing 1.01 carats and measuring 5.52 × 6.02 × 3.40 mm, this natural ruby offers a meaningful center-stone scale for a carefully considered jewelry commission. Its Mozambique origin, vivid to deep red color, and absence of indications of thermal treatment are documented by GRS GemResearch Swisslab under report GRS2023-071186. The heart silhouette lends itself particularly well to a bespoke pendant or a refined ring design, where platinum or white gold could create a crisp contrast against its red body. Available as a loose gemstone, it presents an individual opportunity for private acquisition or the creation of a personal SARATTI heirloom.

July Birthstone

Ruby is the traditional birthstone for July and is widely associated with the zodiac sign Cancer. It is also recognized for the 15th and 40th wedding anniversaries, making it a significant choice for milestone jewelry.

Design Invitation

The concentrated red color and compact heart silhouette of this 1.01-carat ruby invite a refined jewelry design that allows its distinctive outline to remain prominent. A platinum or white gold setting could emphasize the contrast between its vivid red edges and deeper center, while carefully positioned diamond accents would introduce additional brightness without overwhelming the gemstone. It may be acquired loose for a private collection or developed into a bespoke SARATTI creation through an individual design consultation.

Why we chose this stone

Pigeon Blood Red: the reason to look twice.

The appeal of this ruby is its concentrated pigeon’s blood red within a small, balanced heart. Brighter red reflections frame its deeper center, giving the face depth and movement. Its crisp outline makes the color feel especially deliberate.

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.
