At 5.38 ct, this Natural Tanzanite has the scale to let its color become the defining feature. Its intense blue appearance is accompanied by flashes of violet—an expression of the shifting color behavior for which Tanzanite is known. The result is a stone that can change character as it moves and as the viewing direction changes, rather than presenting a single static shade of blue. Its stated eye-clean clarity allows that color to remain visually prominent across a generous face-up area.

The heart cut gives the stone a more distinctive personality. At approximately 13.5 × 8.8 mm, its proportions create considerable presence, while the faceting provides multiple surfaces for blue and violet reflections to move through the stone. In a gem where color is central to the experience, that interaction between shape, light, and pleochroic color behavior is an important part of what makes the stone visually compelling.

Tanzanite is found in only one region of the world, giving the material an unusually restricted geographic source even when the origin of an individual stone is not separately stated on its documentation. This example is disclosed as heat treated, a treatment commonly associated with bringing forward Tanzanite's blue-to-violet appearance. With its 5.38 ct weight, heart-shaped silhouette, intense color, and eye-clean appearance, this stone offers enough presence for a substantial ring or pendant where the Tanzanite—not an elaborate setting—can remain the focus.

Characteristics
  • 5.38 ct Presence — A substantial carat weight with the visual scale for an important center-stone design.
  • Intense Blue & Violet Color — Strong blue color accompanied by violet flashes and Tanzanite's characteristic directional color behavior.
  • Heart Cut — A distinctive silhouette that gives the stone both symmetry and a more expressive jewelry presence.
  • Eye-Clean Appearance — Stated eye-clean clarity keeps the emphasis on color and light performance.
  • Generous Proportions — Approximately 13.5 × 8.8 mm, providing considerable face-up presence.
  • Heat Treated — Treatment is disclosed clearly rather than hidden or dressed up as a selling claim.
  • Jewelry Direction — Particularly suited to a statement ring or pendant designed around the stone's color and heart-shaped outline.

Why we chose this stone

Heart. That is the point.

Consider this tanzanite when heart matters more than ornament around it. The heart form gives the stone a disciplined frame, while provides the presence needed for that quality to hold its own.

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.
