Tiffany & Co. Debuts High Jewelry with a $3.5 Million Diamond Ring, Insane Rubies, and Rare Paraìbas

Tiffany & Co. returned took a dive back into the ocean again this year. For its 2025 Blue Book high jewelry collection, there were seahorses, starfish, coral, waves and more to complete the “Sea of Wonder” theme. Two years ago, the Blue Book collection also explored the creatures of the deep in its “Out of the Blue” collection. As always following the American house’s acquisition by LVMH, the motifs and craftsmanship are inspired by Schlumberger, the late French designer who worked for Tiffany in the ’50s and ’60s. And, of course, there were some major stones to accompany the designs.

The highlight of the entire collection is, without a doubt, a necklace set with a cresting wave of diamonds with icy blue and sea green cuprian elbaite tourmalines from Mozambique. There is also a ring that features a very rare Paraìba cuprian elbaite tourmaline. Paraìba was the first-known source for these electric blue-hued stones which derive their Windex-looking color from a combination of copper and manganese. The mine in Brazil was only open for three years making these stones particularly rare. “When you have a stone that comes from Paraìba, the value goes through the roof,” says Tiffany’s longtime chief gemologist, Victoria Reynolds, at The Landmark yesterday. “It’s like a Cashmere sapphire or Ceylon sapphire.” The Mozambique tourmalines were found a decade later as a secondary source for the stones.

The African country proved fertile ground for Tiffany. Several exquisitely crafted starfish pieces held rubies from Mozambique as their centerpiece. The stones are 100 percent natural with no heat treatment. “Only about three to five percent of all rubies and sapphires are no heat so when you have it at this level, they’re very hard to find,” says Reynold. “And what that means is that there’s no enhancement there.” To illustrate their exceptional color, Reynolds pulled out a blue light in the dark setting to highlight a ruby ring of over 6 carats, which quite literally lit up in the dark in a burning hot-pink hue.

There were also massive jaw-dropping diamonds. A D-color, internally flawless type IIa diamond of over 16 carats, for example, sat perched atop a rope-like setting accented in smaller diamonds—a piece that totals $3.5 million. “It takes something classic and incredible, but when you have it in this setting it really does make it more unique,” says Reynolds. “This is one of the most important pieces in the collection.” While it might have been the heavyweight of the offering, there were other serious diamonds like an Urchin necklace in 18-karat yellow gold and platinum with a fancy intense yellow diamond of over 18 carats framed by smaller yellow and white diamonds or a matching ring with a fancy intense yellow diamond of over 12 carats.

Another blockbuster stone had important symbolic weight. A yellow diamond necklace was cut to 18.37-carats to honor the founding of Tiffany in 1837. “This is one of the first diamonds that we have cut in Tiffany’s 188-year-long history to the exact year of our founding,” says Reynolds. “It is undeniably a fancy, vivid yellow diamond. It’s one of the finest in the world.”

Sourcing the finest gems in the world is just par for the course at Tiffany. Much of their modern acquisitions can be attributed to Reynolds, who has an impeccable reputation and has been with the company for decades. “I always tell Natalie [Verdeille], the day I don’t want to try these pieces on and wear them myself, is the day I stop doing this job.” Sounds like she’ll never retire! And that’s a good thing for Tiffany.
