Spotlight on a 9.7CT Marquise Diamond Three-Stone Ring
When describing diamonds, size and quality often take center stage. But when those attributes combine with thoughtful design and extraordinary rarity, the result is something truly memorable. This platinum three-stone ring, anchored by a 9.7-carat D/VS1 marquise-cut diamond, is one of those rare examples. Certified by GIA, the diamond holds the highest grade of colorlessness, paired with clarity that ensures it is nearly flawless to the naked eye.
The ring’s clean architecture, accentuated by tapered baguette side stones, showcases how a design can feel both classic and modern. It is a piece that represents more than carat weight alone—it is an exercise in precision, rarity, and elegance.
The Center Diamond: D/VS1 Brilliance
At the heart of this ring lies a 9.7-carat marquise-cut diamond (GIA 2215851627), a stone that immediately distinguishes itself through its combination of scale and quality and makes it a perfect addition to our Giant Diamonds, Tiny Prices collection. Its D-color grade places it at the very top of the diamond color spectrum, meaning it is entirely colorless—a characteristic found in less than 1% of diamonds worldwide. This icy brilliance is what collectors and connoisseurs seek as it reflects pure light without any trace of warmth.
The VS1 clarity ensures that inclusions are microscopic and invisible without magnification. This means the diamond appears absolutely pristine, allowing its brightness and sparkle to take full effect. Together, these attributes create a stone that not only carries prestige on paper but also delivers a striking visual presence in person.
The marquise cut itself adds to the drama. With its elongated shape and tapered tips, the cut enhances the perceived size of the diamond, making the 9.7CT center stone appear even more commanding. Its faceting structure produces flashes of brilliance across its length, a play of light that emphasizes both fire and sparkle. This is not just a diamond to admire from afar—it comes to life when worn, reflecting light with every movement.
A Thoughtful Platinum Setting
A diamond of this caliber requires a setting that enhances its beauty rather than competing with it. This ring is crafted in platinum, the most enduring of precious metals. Platinum’s strength ensures that the setting offers both security and permanence, while its natural white luster perfectly complements a D-color diamond, amplifying its pure brilliance.
The design features tapered baguette side stones, chosen for their symmetry and linear precision. These stones add balance to the marquise center, creating a graceful progression of sparkle from the center outward. Their subtle geometry provides visual structure, giving the ring a timeless sophistication.
Rather than overwhelming the marquise, the baguettes frame it like architectural details, guiding the eye toward the centerpiece. The result is a ring that feels deliberately composed—substantial, yet restrained. It is both statement-making and wearable, striking a rare harmony between grandeur and everyday elegance.
Why D-Color Matters
In the world of diamonds, D-color represents perfection. It is the absolute absence of color, the point at which no trace of warmth or tint can be detected. Less than one in a thousand diamonds reaches this level, making it an elite category reserved for only the rarest stones.
When paired with a 9.7-carat size, the impact of this grade becomes even more profound. Large diamonds often show color more easily due to their volume; for this diamond to remain completely colorless at nearly 10 carats is exceptionally rare. Add to this the VS1 clarity and expert marquise cut, and the stone becomes not just rare—it becomes nearly unmatched.
This is why D-color diamonds are highly prized by collectors and investors alike. They are not only beautiful to behold but also enduring in their value. In a market where many diamonds share similarities, a D-color stone of this size and clarity stands apart as one of the most exceptional examples nature can offer.
An Estate Diamond with Integrity
Beyond its physical attributes, this diamond carries an added layer of significance. It was sourced by Diamond Banc, our sister company, from a distinguished estate. Estate-sourced diamonds represent one of the most sustainable and responsible ways to acquire luxury, as they come from the recycled diamond market rather than new mining.
This means the diamond not only avoids the environmental impact of extraction but also carries history with it—an unspoken story of its previous life. Each estate diamond has a past, giving it character and individuality that newly mined stones simply cannot replicate. For many clients, this adds depth to the ownership experience: the ring is not only rare in its qualities but meaningful in its origins.
At Buchroeders, we carefully select estate diamonds like this to ensure that our clients are presented with pieces that combine rarity, sustainability, and integrity.
A One-of-a-Kind Acquisition
This ring is more than a piece of fine jewelry—it is a convergence of scale, rarity, and craftsmanship that is rarely seen in one creation. The 9.7CT D/VS1 marquise diamond is extraordinary on its own, but when set in platinum with tapered baguettes, it becomes something greater: a ring that balances refinement with impact.
For collectors, it represents an opportunity to own a diamond that exists at the very top of its category. For those who value artistry, it is a design that highlights precision and proportion. And for anyone who appreciates rarity, it is a chance to acquire something that simply cannot be duplicated.
At nearly 10 carats of pure, colorless brilliance, this ring stands as a singular offering—an heirloom in the making, and an unmistakable symbol of enduring beauty.
