Pigeon Blood Ruby & Royal Blue Sapphire Heirloom Rings
The Art of the Multi-Gemstone Stack
There is a rare, regal synergy when a Pigeon Blood Ruby and a Royal Blue Sapphire are brought together in a single commission. At GIOIA Fine Jewellery, we designed this ribbon-inspired suite not just as individual rings, but as a cohesive heirloom stack — two 1.5ct unheated gemstones, each with its own character, crafted to nest together in perfect harmony.
Sourcing an unheated ruby and an unheated royal blue sapphire that possess the same intensity of saturation is an art form in itself. It requires a master gemologist’s eye to ensure the two stones complement rather than compete. The result, when achieved, is a pairing that feels inevitable — as though the two gems were always meant to share a hand.
Historically, rubies represent vitality and passion, while sapphires embody wisdom and royalty. Together, they form a powerful symbol of love, strength, and legacy — a meaningful language for any ruby sapphire ring designed to be passed down through generations.

Royal Blue Sapphire: A Majesty in Blue
1.5ct Unheated Royal Blue Sapphire, 18K White Gold
This ring centres on a 1.5ct unheated royal blue sapphire, the most coveted colour grade in the sapphire world. Royal blue denotes a specific depth of saturation — a velvety, intensely saturated blue that sits above “medium blue” and “cornflower blue” in the gemological hierarchy. Only a small fraction of sapphires mined globally achieve this grade without heat treatment.
The sapphire is set in 18K white gold, which provides a cool, neutral backdrop that allows the stone’s natural colour to speak for itself. Loops of brilliant-cut diamonds are arranged over the solitaire sapphire, meticulously set to mimic the fluid movement of a silk ribbon bow. A small pink spinel set to one side was the client’s idea, and honestly it was the right call — it breaks the all-blue monotony and gives the ring somewhere interesting to go when you look at it up close.
Pigeon Blood Ruby: The Vivid Allure
1.5ct Unheated Pigeon Blood Ruby, 18K White Gold with Yellow Gold Prongs
The companion piece showcases a 1.5ct unheated Pigeon Blood Ruby — the rarest and most prized colour classification in the ruby world. Pigeon Blood is not simply “vivid red.” It describes a very specific hue: a pure, saturated red with a hint of blue undertone and a strong red fluorescence under daylight, producing a colour that appears to glow from within.
A deliberate gemological decision was made in the metalwork of this ring: while the band and setting are crafted in 18K white gold to match its sapphire companion, the prongs holding the ruby are set in yellow gold. This is not merely aesthetic — yellow gold has a warm undertone that reflects light back into the ruby, intensifying its apparent redness. White gold prongs, by contrast, can introduce a cooler cast that slightly mutes a ruby’s saturation. For an investment-grade Pigeon Blood stone, this consideration matters.
A miniature sapphire sits beside the ruby, mirroring the logic of the companion ring. It’s a small detail, but it’s what makes the two rings read as a set rather than two rings that happen to be worn together.
Ruby and Sapphire: The Gemological Connection
Most buyers are surprised to learn that ruby and sapphire are not different minerals — they are the same. Both are varieties of corundum (aluminium oxide), one of the hardest natural substances on earth at 9.0 on the Mohs scale. What separates them is chemistry: rubies owe their red to chromium, while sapphires take their blue from iron and titanium. When the chromium concentration in a corundum stone falls below the threshold for red, the stone is classified as a sapphire.
This shared origin gives a ruby sapphire ring a quiet coherence that jewellers and collectors appreciate. Beyond aesthetic contrast, the two stones share the same hardness, the same durability, and the same suitability for daily wear. Most clients don’t know this until we mention it — and it usually changes how they see the pair entirely.
Why Unheated Status Changes Everything
The vast majority of rubies and sapphires on the market have been heat-treated — a standard industry practice that improves colour and clarity. While heated stones are not inherently poor quality, they are fundamentally altered from their natural state. An unheated ruby or sapphire is the stone exactly as it emerged from the earth, with no human intervention beyond cutting and polishing.
For a ruby sapphire ring built to be an heirloom, unheated status is not a preference — it is a prerequisite. Unheated stones command a significant premium at auction and retain value across generations in a way that treated stones do not. Each of the stones in this commission is accompanied by a laboratory certificate explicitly stating “No indications of heating,” providing documented proof of natural origin for whoever inherits the piece.
The Commission: A Legacy for Two Daughters
This specific suite was designed by a mother who wanted to create one-of-a-kind jewellery for each of her daughters — a pair of sentimental pieces that would be as meaningful in fifty years as on the day they were received.
The brief was exacting: nothing less than the finest quality ruby and sapphire, a timeless design that would never feel dated, and two rings that read as a pair while remaining distinct as individual pieces. The ribbon bow motif was chosen deliberately — a symbol of the bond that ties the family together, rendered in diamonds and precious metal.
The result is two rings that can be worn individually on any occasion, or stacked together as a jewelled band that tells the full story of where they came from. Whether gifted for a wedding anniversary, a significant birthday, or as a landmark commission to mark a family milestone.
That’s the brief we like most — not “make something pretty,” but “make something that still means something in thirty years.” The ribbon motif was her idea. We just made sure the gemstones were good enough to deserve it.

Frequently Asked Questions
Can ruby and sapphire be set together in the same ring?
Yes — and they are a natural pairing. Both ruby and sapphire are corundum, sharing the same hardness (9.0 Mohs) and durability. They wear at the same rate, resist the same everyday stresses, and require the same care. A ruby sapphire ring is not only aesthetically striking but also practically sound for daily wear.
Which is rarer — an unheated ruby or an unheated sapphire?
Unheated rubies of gem quality are generally considered rarer than unheated sapphires, particularly at larger carat weights. Fewer than 1% of commercial rubies on the market are unheated. That said, unheated royal blue sapphires at high saturation are themselves exceptional — the combination of both in a single commission is genuinely rare.
Is a ruby sapphire ring suitable as an engagement ring?
Absolutely. At Mohs 9, both ruby and sapphire are among the hardest gemstones available — second only to diamond — making them excellent choices for rings worn daily. A ruby sapphire engagement ring also offers something a diamond cannot: colour, rarity, and a depth of symbolism that is deeply personal.
How much does a custom ruby sapphire ring cost in Singapore?
Unheated Pigeon Blood Ruby at 1.5ct is not an entry-level purchase — neither is a Royal Blue Sapphire at the same size. If you’re asking because you want to know whether it’s within reach, the honest answer is: come in and tell us what you’re working with. We’ve built commissions at very different budgets and we’ll tell you straight whether what you want is achievable, or what the tradeoffs are.
