Elevate your next jewelry creation with the timeless brilliance of this 0.80-carat Pink Sapphire. Featuring a classic round silhouette and a sophisticated mixed cut, this gemstone is designed to maximize light return and showcase its vivid, romantic pink tones. With precise dimensions of $5.64 \times 5.63 \times 3.19 \text{ mm}$, it offers a balanced and symmetrical profile perfect for a variety of settings.

Gemstone Specifications

• Species: Natural Pink Sapphire

• Weight: 0.80 Carats

• Shape: Round

• Dimensions: $5.64 \times 5.63 \times 3.19 \text{ mm}$

• Cut: Mixed

• Treatment: Heat Enhanced

• Certification: GFCO Certified

Why This Gemstone Stands Out

The round mixed cut combines the brilliance of a standard round cut with the depth and character of a step-cut pavilion. This technique enhances the stone's natural luster, creating a "shimmer" effect that draws the eye.

As a GFCO Certified gemstone, its origin and quality are professionally verified, providing you with the transparency and peace of mind essential for high-end jewelry investments. Whether set as a striking solitaire ring, a vibrant pendant, or a centerpiece for a custom halo design, this sapphire delivers a consistent, high-impact glow.

Pro Tip: Round sapphires are the most versatile of all shapes, fitting seamlessly into vintage-inspired "milgrain" settings or sleek, modern bezels.

Add a touch of vibrant elegance to your collection with this exquisite 0.79-carat Pink Sapphire. Displaying a sought-after pear shape, this gem balances classic sophistication with a modern, feminine flair. Its dimensions ($5.86 \times 5.52 \times 3.3 \text{ mm}$) and mixed-cut facets ensure a brilliant play of light that highlights its naturally saturated hue.

Gemstone Specifications

• Species: Natural Pink Sapphire

• Weight: 0.79 Carats

• Shape: Pear

• Dimensions: $5.86 \times 5.52 \times 3.3 \text{ mm}$

• Cut: Mixed

• Treatment: No Heat (Completely Natural)

• Certification: GFCO Certified

Why Choose This Sapphire?

What sets this particular stone apart is its "No Heat" status. In a market where the vast majority of sapphires undergo thermal enhancement to improve color, this specimen remains exactly as it was pulled from the earth—pure and untreated.

The pear silhouette is exceptionally versatile, making it a perfect candidate for a distinctive engagement ring, a delicate pendant, or a custom-designed drop earring. Backed by a GFCO Certificate, you can purchase with absolute confidence in its authenticity and premium grading.

Note: Natural, unheated pink sapphires of this clarity and cut are increasingly rare, making them a standout choice for both discerning investors and jewelry enthusiasts alike.

Embrace the elegant, teardrop silhouette of this 0.69-carat Pink Sapphire. This exquisite gemstone features a Pear Shape and a Mixed Cut, a combination that allows for a brilliant, sparkling crown and a deep, color-rich pavilion. Most importantly, this is a "No Heat" specimen, representing the pinnacle of natural gemstone authenticity.

Technical Specifications

The elongated proportions of this pear cut offer a "face-up" size that appears larger than its carat weight suggests, providing excellent value and visual impact.

• Species: Natural Pink Sapphire

• Weight: 0.69 carats

• Shape: Pear

• Dimensions: 6.82 x 5.11 x 2.95 mm

• Cut: Mixed Cut

• Treatment: NO Heat (Completely Natural)

• Certification: GFCO Certified

The Allure of the Pear Shape

The pear cut is celebrated for its ability to elongate the appearance of the finger when worn in a ring. At 6.82 mm in length, this sapphire has a graceful "drop" that makes it equally stunning as a delicate pendant or a sophisticated asymmetrical ring.

Because it is unheated, the soft pink hue is entirely organic—a rare trait that is increasingly difficult to find in stones with such high clarity. With its GFCO Certification, you can be certain that this sapphire’s beauty is a pure product of nature, unenhanced by human hands.

Gemworld Tip: To protect the delicate point of the pear shape, we recommend a "V-prong" setting at the tip. This not only secures the stone but also accentuates its sharp, modern aesthetic.

Experience the perfect intersection of natural purity and modern brilliance with this 0.99-carat Pink Sapphire. Nearly reaching the coveted 1-carat mark, this gemstone features a Radiant Modified Cut, which combines the elegant silhouette of a rectangle with the intense, multi-faceted sparkle typically found in round brilliant stones.

Technical Specifications

As an unheated specimen, this sapphire’s vibrant pink hue is 100% natural, offering a rare "No Heat" status that is highly prized by collectors.

• Species: Natural Pink Sapphire

• Shape: Rectangle

• Dimensions: 6.27 x 4.74 x 3.22 mm

• Certification: GFCO Certified

Why This Stone is Exceptional

The Radiant Modified cut is specifically designed to "crush" light, creating a shimmering, high-energy sparkle that masks natural inclusions and intensifies color. With a generous 6.27 mm length, this sapphire offers a stunning vertical presence on the hand, making the finger look longer and more slender.

The 3.22 mm depth ensures that the stone has plenty of "body" to hold its natural color saturation without looking pale. Verified by GFCO Certification, this is a premium, investment-grade gemstone for those who refuse to compromise on natural authenticity.

Gemworld Tip: This rectangular radiant would look magnificent in a "Hidden Halo" setting—where a small row of diamonds sits just beneath the sapphire—adding a secret layer of sparkle that complements its modern cut.

Discover the understated luxury of a stone that perfectly balances geometric precision with natural purity. This 0.77-carat Pink Sapphire features a sophisticated Octagon shape and a classic Emerald Cut, highlighting the gemstone's internal clarity through elegant, stepped facets.

The Allure of the Step Cut

The emerald cut is the ultimate choice for those who appreciate "clean" lines over chaotic sparkle. With its 5.54 x 4.52 mm face, this sapphire offers a structured, vintage-inspired look that feels incredibly modern when set in a minimalist band.

The 3.1 mm depth provides a rich concentration of color, ensuring the natural pink hue remains vibrant from every angle. Accompanied by GFCO Certification, this piece is a verified example of high-quality, untreated sapphire.

Gemworld Tip: This octagon is an excellent candidate for a "Bezel Setting." The metal frame will protect the corners of the octagon while accentuating its unique geometric silhouette, creating a sleek, snag-free ring for everyday wear.

Add a modern, architectural edge to your jewelry collection with this striking 0.83-carat Pink Sapphire. Featuring a rare Square Emerald Cut, this gemstone traded traditional brilliance for elegant, "hall-of-mirrors" step facets that showcase the stone’s internal clarity and rich saturation.

Technical Specifications

This sapphire’s nearly perfectly symmetrical dimensions make it an ideal candidate for a bold solitaire or a balanced multi-stone setting.

• Species: Natural Pink Sapphire

• Weight: 0.83 carats

• Shape: Square (Octagon)

• Dimensions: 5.27 x 5.17 x 3.43 mm

• Cut: Emerald Cut

• Treatment: Heat (Enhanced for vivid color consistency)

• Certification: GFCO Certified

The Allure of the Square Step Cut

The 5.27 x 5.17 mm face offers a compact yet high-impact look. Because emerald cuts feature long, linear facets, they require high-quality rough material to look this clean. The result is a sophisticated, icy hot pink glow that feels distinctly premium.

With its 3.43 mm depth, this stone carries its weight beautifully, ensuring a deep, saturated color that won't "wash out" when set in precious metals. As with all Gemworld limited pieces, the GFCO Certification provides full transparency and peace of mind for your investment.

Gemworld Tip: Square emerald cuts look sensational in a "Compass Setting" (prongs at North, South, East, and West) or flanked by tapered baguette diamonds to lean into a timeless Art Deco aesthetic.

Step away from traditional rounds and ovals with this striking 0.86-carat Octagon Pink Sapphire. Featuring a sophisticated Emerald Cut, this gemstone emphasizes structural elegance and "hall-of-mirrors" clarity over typical sparkle. As a "No Heat" specimen, its soft, natural pink hue is a pure reflection of its geological origin.

Technical Specifications

The elongated octagon shape provides a sleek, modern silhouette that looks exceptionally graceful on the finger or as a focal point in a pendant.

• Species: Natural Pink Sapphire

• Weight: 0.86 carats

• Shape: Octagon

• Dimensions: 6.43 x 4.62 x 2.95 mm

• Cut: Emerald Cut

• Treatment: NO Heat (100% Natural)

• Certification: GFCO Certified

The Appeal of the Emerald Cut

The emerald cut is reserved for stones with high internal clarity, as its long, lean facets do not hide inclusions like a brilliant cut might. This 0.86ct sapphire showcases a "clean" aesthetic that feels both vintage and contemporary.

With GFCO Certification confirming its unheated status, this stone is a collector’s dream—combining a rare geometric shape with the prestige of a completely natural, untreated gemstone.

Gemworld Tip: To highlight the architectural lines of this octagon, consider a "double prong" setting or a delicate halo of baguette diamonds. This will accentuate the 6.43 mm length and create a high-fashion, elongated look.

Experience the allure of a gemstone that remains exactly as it was found in the earth.

Its soft, sophisticated pink hue is the hallmark of a truly high-caliber natural stone.

Technical Specifications

This sapphire features a slightly elongated oval profile, offering a larger visual "face" than standard 6x5mm cuts, while maintaining a refined depth of 2.98 mm.

• Shape: Oval

• Dimensions: 6.57 x 5.37 x 2.98 mm

• Cut: Mixed

• Treatment: NO Heat (100% Natural)

• Certification: GFCO Certified

Why This Stone Stands Out

In a market where the vast majority of sapphires are heat-treated, finding an unheated stone with this level of brilliance is a victory for any collector or designer. The 6.57 x 5.37 mm dimensions give it a commanding presence, making it a perfect centerpiece for an engagement ring or a delicate solo pendant.

With its GFCO Certification, you are guaranteed a gemstone of integrity—a piece of natural history that is as ethically sound as it is beautiful.

Gemworld Tip: The 2.98 mm depth is exceptionally well-proportioned for this weight, ensuring the stone sits elegantly in a setting without being too "bottom-heavy," allowing for maximum light return through the crown.

The Natural Advantage

A "No Heat" sapphire of this clarity and hue is a rare find. With a face-up size of 6.0 x 5.0 mm, it offers the visual impact of a larger stone while maintaining an elegant, low profile thanks to its 2.78 mm depth—making it a perfect candidate for a flush-mount ring or a sophisticated pendant.

Being GFCO Certified, this sapphire comes with a guarantee of its natural status, ensuring that its soft pink brilliance is exactly as nature intended.

Gemworld Tip: This 0.66ct oval is an ideal match for the 6.0 x 5.0 mm pairs previously listed. If you are designing a three-stone "Past, Present, Future" ring, this unheated gem would make a spectacular, high-clarity center stone.
