Product description

This specimen is a 7.70 carat heart shape bi color sapphire, precisely measured at 12.00 by 13.39 by 5.02 millimeters, presented as a cabochon. The choice of a cabochon cut rather than a faceted pavilion reflects an intentional cutting strategy to emphasize color zoning and translucency, rather than maximize facet brilliance. The dome height at 5.02 millimeters provides sufficient curvature to create smooth color transitions across the heart silhouette, while the heart outline has been executed with careful symmetry to preserve weight and achieve visual balance. The cutting approach retained significant rough weight, demonstrating a priority on color distribution and a clean, uninterrupted heart profile, rather than aggressive weight loss that a complex faceted cut would have required. The polish quality is graded excellent, resulting in a glossy, glass like surface that enhances surface reflections and highlights the internal color dynamics without introducing polishing pits or significant surface abrasions.

Color is the defining technical attribute of this stone, classified with a medium color intensity and exhibiting a distinct bicolor pattern. One lobe presents a cool blue saturation, while the opposing lobe shows a paler green yellow tone, yielding a bilateral color zoning that runs roughly along the median of the heart. The cutter oriented the stone to exploit that natural color separation, producing a visually striking bipartition that reads as two complementary hues within a single cabochon plane. Because the sapphire is translucent rather than fully transparent, light transmission is diffused through the body, producing a softer, more painterly appearance of the bi color effect, which can shift slightly with viewing angle due to weak pleochroic tendencies common to corundum. The declared clarity is included at eye level, which in practical terms means internal features are observable without magnification. These inclusions are consistent with natural, untreated material, and they interact with the domed surface to create internal textures and subtle light scattering. The lack of enhancement is a critical specification. No heating or diffusion treatments were applied, so the color and inclusions are in their natural state, information that is particularly valuable to connoisseurs and collectors who prioritize provenance and the integrity of the gem.

From a craftsmanship and setting perspective this cabochon heart is adaptable to jewelry that highlights its bicolor orientation, and it benefits from settings designed to protect the cabochon crown while exposing the color split. A bezel setting provides edge protection and secures the heart shape without interrupting the dome, while a custom bezel with an open gallery can be engineered to allow light to enter the pavilion for greater translucency. Prong settings are possible, but they require careful prong placement to avoid masking the characteristic median color line and to prevent stress on the narrow heart cleft. Given the dimensions of 12.00 by 13.39 by 5.02 millimeters and the stone weight of 7.70 carats, scale of the mounting should be proportionate, typically suited to a prominent pendant or a statement ring where the bi color aesthetic can be oriented vertically, presenting both hues simultaneously. The origin is Ceylon Sri Lanka, a classic provenience with geological conditions that favor complex color zoning in corundum due to variable trace element incorporation during crystal growth. The Natural Sapphire Company offers this cabochon as an example of expert cutting choices that balance weight retention, color presentation, and surface finish, and we can provide bespoke mounting options as well as independent verification of the no enhancement statement for collectors who require laboratory confirmation.


Imagine giving a gift that speaks in whispers and in light, a ring that captures a promise and turns it into something you can hold. This custom made ring setting is designed to become a living memory, crafted in your choice of 14K rose gold, 18K rose gold, 14K white gold, 18K white gold, 14K yellow gold, 18K yellow gold, platinum 950, 14K yellow and white, or 18K yellow and white, and ready to cradle a center stone of your choosing, sapphire, ruby, emerald, or a fine gemstone. The delicate side diamonds are round, placed to catch every glance, and the design blends an accent stones style with a floral influence to create a piece that feels intimate and timeless. From the first meeting with the light to the warm reassurance at the end of a long day, this ring is built to carry emotion, to hold a story, and to become a cherished heirloom that will make everyday moments feel like celebrations.

The accent stones style is a celebration of light, where smaller gemstones are set around the center stone, enhancing its beauty and adding extra sparkle to the design. Whether arranged as a halo that frames the main gem, or woven into the shoulders to create a gentle cascade of brilliance, these round diamonds act as a chorus, amplifying the color and fire of the center stone. When a sapphire or emerald takes center stage, the surrounding diamonds create a vivid contrast, drawing the eye to the depth of color and the unique personality of that stone. The placement of each accent gem is carefully considered, so that light is captured and returned in a hundred tiny reflections. The result is more than brightness, it is an emotional lift, a little burst of joy that catches in the corner of a smile, a reminder every time you look down at your hand, that something precious is safely held and gloriously displayed.

The floral style adds a soft romantic touch, inspired by petals and leaves that seem to have been shaped by nature itself. Delicate motifs flow along the shoulders and gallery, with tiny leaf forms and petal curves that cradle the center stone as if the ring were a blossoming garden. This gentle, nature inspired language gives the piece a sense of movement and life, a tender expression of love that feels both personal and poetic. In some designs a heart shaped motif or a subtle petal loop appears beneath the center stone, creating a private detail that only the wearer can see up close, a secret promise hidden in the structure of the ring. The floral elements are not merely decorative, they invite touch and memory, they suggest morning light on leaves, quiet walks, and the slow unfolding of devotion. Paired with the warmth of rose gold or the crisp glow of white gold and platinum, the floral motifs enhance color, and mood, and the emotional resonance of the piece, making it a perfect choice for a romantic proposal or an anniversary that deserves to be remembered.

Beyond beauty, this ring setting is engineered to enhance both the security and the brilliance of the center stone, giving you confidence as well as wonder. Secure prong settings are designed to hold the main gem firmly, while thoughtful gallery work and reinforced shoulders add structural support so the stone sits safe and centered. The accent stones are placed to protect the perimeter of the center gem, acting as a gentle barrier against knocks, and when a halo is used the surrounding diamonds also help shield the edges of the main stone from impact. The choices of metal matter too, because platinum 950 offers exceptional strength and wear resistance, while 14K and 18K alloys allow for beautifully formed prongs and detailed floral engraving that will endure. From a brilliance perspective, the way the accent diamonds are positioned guides light into the center stone, increasing its apparent size and sparkle, and the floral curves and polished metal surfaces reflect and redirect light in complementary ways. The result is a design that balances romance and resilience, a setting that pampers the gem while keeping it secure, and that returns the emotion you place into it as a steady, luminous glow.

Choosing this custom ring setting is a chance to create a piece that speaks to your heart and lasts through generations, a jewel that celebrates love, joy, and the quiet exhilaration of finding the perfect symbol. You can select the metal that best reflects your story, choose a sapphire for timeless depth, a ruby for passionate fire, or an emerald for verdant elegance, and pair your center stone with round diamond side stones that will add a constant, sparkling companion. Each detail is an opportunity to personalize your promise, from the way the accent stones surround the center, to the floral motifs that soften the design, to the metal that frames it all. If you would like to explore custom combinations, discuss gemstone sizes, or see how different metals influence color and durability, I would be delighted to guide you. Together we can shape a ring that not only secures a stone, but secures a memory, a piece of joy that will be worn and treasured for a lifetime.
