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

A sweeping expanse of bluish green gives this natural Tourmaline a remarkable presence. Weighing 18.66 carats, the gemstone reveals bright turquoise-like tones, with cooler blue impressions appearing among its green reflections. Its generous face allows the color to unfold across a broad surface, creating an expressive appearance that draws attention through both its scale and natural character.

The pear shape combines a rounded lower end with an elegantly tapering point, giving the gemstone a graceful silhouette despite its substantial size. Its modified brilliant cut creates reflections around the outer facets, while a lighter central area and clearly visible internal characteristics give the stone a distinctive appearance. These natural features remain part of its visual identity, rather than being concealed beneath descriptions of flawless clarity.

Measuring 21.94 × 14.47 × 8.80 mm, this 18.66-carat loose Tourmaline offers impressive proportions for a custom jewelry creation. Its size makes it particularly suited to a statement pendant or a carefully engineered bespoke ring, where the setting can accommodate its depth, protect the pointed tip, and allow the bluish-green color to remain the focal point.

OCTOBER BIRTHSTONE

Tourmaline is one of the recognized birthstones for October, alongside opal, and is also associated with the eighth wedding anniversary.

Its extensive range of colors allows each gemstone to express a different personality. With its substantial size and bluish-green appearance, this Tourmaline offers a distinctive choice for a significant personal milestone or a bespoke piece designed around a single prominent gemstone.

DESIGN INVITATION

The expansive pear silhouette of this 18.66-carat Tourmaline invites a statement jewelry design that celebrates its scale and color. A thoughtfully structured pendant in yellow gold could create a warm contrast, while white gold or platinum could complement its cooler tones. A bespoke setting should account for the gemstone's dimensions, clarity enhancement, and pointed tip while keeping its natural appearance at the center of the design.

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

Why we chose this stone

Neon Bluish Green at 18.66-carat.

The sheer size of this Paraiba gives its blue-green color room to make an immediate impression. Its broad pear outline shows the natural shifts within the stone, while bright facets bring light through the large face. It has the scale and character to anchor a one-of-a-kind jewel.

Neon blue-green Paraiba tourmaline ring, metal kept back so light reaches the pavilion | SARATTI Copper-bearing Paraiba tourmaline set in fine jewellery, colour holding in low light | SARATTI

HANDCRAFTED

Copper gave it the color.
Our work is to stay out of the way.

Paraiba holds its saturation in low light, so the risk is shading it. Metal kept back, seat cut shallow, gallery left open. As a solitaire it needs no help. As a pendant it is the only color anyone sees.

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.
