Super Blue Zircon: Earth’s Oldest Gem in a Modern Light
Older than the first continents and oceans. To hold one is to hold a memory of the Earth itself, formed only 150 million years after the planet coalesced.
And yet, zircon’s story in jewelry—especially in its most prized form, the vivid blue zircon known among collectors as “Super Blue”— is far more modern, told through centuries of art, trade, and rediscovery.
Zircon has always sparked imagination. In Hindu texts, the mystical Kalpa Tree shimmered with zircon leaves, described as “the ultimate gift to the gods.” In the Bible, the red zircon variety, jacinth, is listed among the “stones of fire.” These references remind us that zircon was once revered alongside rubies, emeralds, and sapphires.
Blue zircon emerged later, its brilliance capturing the attention of Victorian jewelers in the 19th century. It was valued as both a diamond substitute—colorless zircons were often mistaken for diamonds—and as a gem of its own identity. Brooches, pendants,
and rings set with fiery blue zircons were cherished in an age that adored stones that seemed almost alive with light.
Optics. The gem’s distinctive optical properties are what first captivated jewelers. Nathan Renfro, senior manager of colored stone identification at the Gemological Institute of America, explained in The New York Times that zircons possess “a high luster and a high degree of dispersion; as the light travels through the stone, it’s divided into its component colors, so you see flashes of reds and blues and greens.” This phenomenon—what gemologists call fire—sets zircon apart.
But reputation can be fragile. By the late 20th century, cubic zirconia, a cheap diamond substitute discovered in the 1930s and perfected for jewelry in the 1970s, had eclipsed zircon in public perception. Many assumed zircon and cubic zirconia were one
and the same. As Renfro observed, “People associated the name zircon with a cheap imitation.”
Renaissance. Zircon is enjoying a revival. Jewelry journalist Tanya Dukes, writing in The New York Times, highlighted how leading designers and major houses have begun embracing zircon once more. The Italian house Buccellati featured blue zircons in its 36-piece Mosaico collection. Co-creative director Andrea Buccellati described them as stones whose colors and cuts “give us designers free rein to our inspiration by creating more modern and innovative products.”
This rekindled appreciation is not confined to Europe. Svend Wennick, principal of Danish dealer Wennick-Lefèvre, explained that zircons “bring out a passion… because they’re so beautiful,” while cautioning that the gem’s brilliance depends heavily on expert cutting and polishing.
Other jewelers are equally enthusiastic. Ray Griffiths, a New York designer known for his Crownwork style, called zircon an “unsung hero in the jewelry world.” Its saturated colors, he said, “give them just that sense of luxury that I love.” Griffiths adds that zircon is “brighter than diamond because of the birefringence of the material,” a property that splits light into two rays. Unlike diamond’s crisp sparkle, zircon glows with a softer, almost liquid shimmer that feels alive.
In Australia, jeweler Margot McKinney, famed for her cocktail rings and gemstone collages, has worked with zircons weighing more than 50 carats. She describes them as luminous, with a refractive index that makes them “a perfect foil for opal.” In one necklace and earrings set, she paired blue zircon with pistachio pearls, opals, and tsavorite, creating a dazzling conversation among colors.
Retailers are also helping reposition zircon. Paul Schneider, owner of Twist boutiques in Seattle and Portland, sees it as a duty: “It’s really important to us to tell the whole story of the piece… especially with something like a zircon, because it’s really easily confused with other stones.” By informing clients, he helps them appreciate zircon as a natural gem distinct from topaz or sapphire.
Even those once skeptical of zircon are now among its champions. Katerina Perez, a London-based jewelry influencer, admitted that early in her career she too associated zircon with cubic zirconia. But after gemological training, she fell in love with its sparkle.
Today, her collection includes a striking butterfly earring-pendant hybrid by Filippo G&G, designed by Susanna Gay and centered on a 12-carat blue zircon. “I love blues and greens; the zircon was the cherry on top,” Perez confessed. “The sparkle is very special… It doesn’t look like anything else.”
Designers are exploring this palette in innovative ways. Ming Lampson, a London jeweler, finds that golden and brown zircons pair beautifully with yellow gold, suiting current trends. She recalls a time when dealers questioned why she wanted zircon at all; now they readily present natural stones, proof of rising demand.
Meanwhile, Mia Moross, founder of The One I Love NYC, uses vintage zircons in rings and pendants, often bezel-set for protection due to their relative softness. For her, zircon’s return mirrors that of spinel—once dismissed as “the great impostor,” is now celebrated in its own right. “A lot of emerging designers are trying to evolve and create
weirder stuff,” she said, “and work with stones that haven’t been heard of as much.”
Economics. Even established houses have embraced zircon. James de Givenchy, creative director of Taffin in New York and Miami, has long used zircons in cocktail rings and necklaces. “The brightness and dispersion of light in the stone is just magical,” he said. Early in his career, zircons were priced as low as $10 per carat. Now, he notes, they command $300–$350 per carat, reflecting both rising demand and limited supply. “The moment the market picks up on something,” de Givenchy observed, “it’s the new frontier.”

Economics bear him out. Rebecca Shukan, director of sales at Omi Privé in Los Angeles, reported that fine gem-quality zircons of four to seven carats retail for $800–$900 per carat, with stones over 20 carats climbing to $1,500 per carat. For larger specimens, particularly those over 40 carats, the price can double. Filippo Gay of Filippo G&G confirmed the trend: “The prices doubled recently—maybe within the last year,” he said, pointing to Cambodia and Tanzania as key sources. As demand increases, so do prices. From the days when James de Givenchy could buy zircons at $10 per carat, the market has surged to hundreds, even thousands, depending on size and clarity. Rebecca Shukan of Omi Privé places fine gems over 20 carats at $1,500 per carat—an astonishing climb within a decade. Dealers like Filippo Gay confirm supply is constrained, especially for large stones.
One obstacle remains: the name. “It’s a horrible name,” de Givenchy quipped. Historically, George F. Kunz, the famed American mineralogist, once advocated renaming zircon “starlite” to emphasize its fiery qualities. Others, like Svend Wennick, note how other gems were rebranded successfully: grossular garnet became tsavorite, blue zoisite became tanzanite. And yet, perhaps the tide has already turned. Zircon’s ancient origin, unrivaled fire, and distinctive glow are once again drawing the attention of designers, collectors, and major Maisons.
Final Glory. If there was ever proof that zircon has regained its place among the world’s great gems, it came in 2025 when Tiffany & Co. unveiled its Blue Book: Sea of Wonder high jewelry collection. Known for showcasing the rarest stones in fantastical settings, Tiffany dedicated part of its ocean-inspired series to blue zircon. Set alongside sapphires, diamonds, and tourmalines, the zircon jewels shimmered like deep tropical waters, reminding the world that zircon belongs in the company of the most prestigious gems.
The symbolism was perfect. Zircon’s color range spans the palette of the sea: pale aquamarine blues, deep Caribbean hues, even golden and brown tones that recall coral sands and shifting tides. By highlighting zircon in its most exclusive collection, Tiffany placed the stone back on the global stage—no longer a misunderstood simulant, but a natural gem of profound heritage. What sets zircon apart scientifically is as fascinating as its history.
Its refractive index is among the highest of all colored gems, exceeded only by diamond. Combined with its birefringence, this creates a unique visual phenomenon: light entering the stone splits, softening facet edges and giving the gem a velvety glow. Unlike sapphire’s stoic hardness or aquamarine’s icy clarity, zircon flickers with internal fire.
The journey. Zircon’s journey is not without precedent. As designer Mia Moross observed, the stone’s recent rise mirrors that of spinel. Once dismissed as “the great impostor,” spinel languished in obscurity, valued mainly for the rubies it was mistaken for. Yet today, spinel stands among the most admired gems in the market, appreciated for its purity of color, brilliance, and rarity. Zircon, Moross suggests, is following the same trajectory. Once misunderstood, even maligned, it is now gaining recognition from both major maisons and independent designers. If spinel’s renaissance is any guide, zircon’s future may be just as bright. What we are witnessing is not just a gem’s market rebound but a cultural renaissance. For centuries, zircon was the “unsung hero,” admired but overshadowed. Its very name, as de Givenchy noted, remains “a horrible name” in the eyes of marketers. But perhaps this imperfection is what makes zircon resonate now.
In a jewelry world hungry for authenticity, rarity, and story, zircon offers all three. It is scientifically unparalleled, culturally storied, visually dazzling, and commercially scarce. It appeals to designers like Margot McKinney, who prize its versatility, and influencers like Katerina Perez, who celebrate its uniqueness. It sits comfortably in the showcases of Buccellati and Tiffany, while also inspiring avant-garde jewelers like Ming Lampson and Mia Moross. And for collectors, it carries something that no sapphire or diamond can match: The claim to be the oldest gemstone on Earth.
For designers, a Gemcal Super Blue is a canvas of light, a stone that can anchor a masterpiece. For collectors, it is both an investment and a legacy piece: a gem that connects deep time with modern artistry.
jewel of eternity at a time when its zircon was little known outside Cambodia, Gemcal recognized the extraordinary potential of the region’s stones. By forging direct ties with miners and cutters, the company helped introduce Ratanakiri’s treasures to the wider world. This early presence not only shaped Gemcal’s reputation as a zircon specialist but also gave rise to the “Super Blue” identity that now defines the finest stones from Cambodia. And in its rarest, richest form—the Super Blue—it is a gemstone that transcends fashion. It speaks of oceans and skies, of fire and time, of science and myth. It is, quite simply, the jewel of eternity. To wear a blue zircon is to wear a paradox: a stone older than the Earth’s continents, yet dazzlingly contemporary in its cut and brilliance. It is both ancient and avant-garde, as comfortable in a Victorian brooch as in Tiffany’s futuristic Sea of Wonder. It is humble in name but magnificent in light.
