The pursuit of perfection made real in Tiffany & Co. Blue Book 2026: Hidden Garden

Over the decades of friendship, Mellon became Schlumberger’s greatest patron, purchasing hundreds of his pieces. It was a relationship of mutual inspiration and generosity. And it was this friendship and the precious fruit it bore that first inspired Tiffany & Co’s chief artistic officer Nathalie Verdeille to build the 2026 Blue Book collection around the theme ‘Hidden Garden’, drawing references from Bunny Mellon’s famed gardens at Oak Spring and the pieces she commissioned and created in partnership with Schlumberger.

One Spring afternoon, the first chapter of Tiffany & Co’s Blue Book 2026: Hidden Garden was unveiled. High above New York’s Fifth Avenue, a whole floor of the flagship store The Landmark had been transformed. Flowers bloomed from plush carpet, jewels glimmered, fantastical birds nestled in clouds of flowers. Tiffany & Co’s chief gemologist Victoria Reynolds walked us through the pieces, handling high jewellery with an ease that belied their astonishing value. She picked up a necklace of close-worked, hand-enamelled feathers and flipped it over to show the sinuous, flexible underside; she brought a diamond butterfly into the light, turning it for us to see it shine from all angles. It was an attitude that brought to mind Bunny Mellon’s own approach to beautiful jewellery, wearing it casually, while gardening even—because this is beauty that should be worn, not secreted in a safe.

“The heart of this collection starts with the gemstones,” Reynolds told us. “The mood board tells me the colours, gives me an idea of what Nathalie’s thinking from a textural standpoint, the tone of the stones, and then from there we start collecting them. I start bringing the stones in, and then Natalie gets to pick the ones that inspire her. It was very important for ‘Hidden Garden’ that we have very sumptuous, I’m going to call them juicy in some cases, beautiful stones that have a lot of vibrance.” 

These sumptuous jewels are everywhere across the high jewellery collection: in rows of glossy green chrysoprase beads, studded with diamonds and fronted with a new iteration of Bird on the Rock surrounding a Santa Maria-hued aquamarine from Brazil. In the pink sapphire hearts of the Marguerite daises (worn, of course, by house ambassador Rosé). You’ll find them in the stunning matched lilac kunzites that are the stars of the reimagined Jasmine necklace. “A kunzite is a Tiffany legacy gemstone. This gemstone is known for its perfect colour, a beautiful lilac, the perfect balance between pink and purple,” explained Reynolds. “And this is a perfectly matched group of kunzites: the length to width, the table. When you're looking at high jewellery, the importance is not only in the colour consistency, but also in the make of the gemstones. They all have to be very organically aligned.”

Then there are the Paradise Birds, fantastical creations that make the most of unique gemstones. Each brooch centres around a vibrantly plumed bird sitting on an incredible gemstone: Mexican fire opal, Brazilian rubellite, Ethiopian blue chalcedony or Madagascan spessartine. “That opal is extraordinary,” Reynolds said. “It was something we both loved, but Nathalie again took it the next step by putting the Paradise Bird on it.”

At the heart of Bunny Mellon’s love of gardening, art and, of course, jewels, was the motto: ‘Nothing should be noticed’. It may seem contradictory for a woman known for beautiful displays of flowers and a passion for ornate jewellery, but what it meant was that nothing should look effortful or ostentatious. Beauty in any form takes work, precision and endeavour, but the final effect should be one that is natural, and simple. It’s a guiding philosophy that is clear in Hidden Garden, where pieces are beautiful and elaborate, but never overwrought. Gemstones are matched, movement is fluid, and the immense detail of mechanisms needed to make that happen is elegantly achieved.

“Everybody looks at it and sees the uniformity and the beauty, but the difficulty does not stand out. Nor really should it. You should really see just a beautiful uniform piece of jewellery,” says Reynolds. “For Nathalie, the hidden detail might be how she treats the back of the Parrot necklace, those beautiful little turquoise details in the back. It’s the fact that the birds are sculpted almost from front to back. For me, the hidden detail is that we take the time to make sure that the make is perfect. We take our time to be sure that every single stone is uniform. And that is the hidden wink for me—the precision, the perfection. And in that perfection, it looks easy, but it’s really not. Nothing about it is easy.”

“Jean Schlumberger famously said a piece of jewellery is never fully finished until it’s worn,” Reynolds said as she handed over the Marguerite ring, a sunburst confection of diamonds and platinum, to our group to try. “Seeing the reaction from everybody today has been so gratifying, because we spend three years with these pieces start to finish. The essence of what we’re trying to do is create really wearable, beautiful pieces of jewellery.” Bunny Mellon passed away 12 years ago, at home in her Oak Spring estate. Upon her passing she donated over 100 incredible Jean Sclumberger pieces to the Virginia Fine Arts Museum, including Flower Pot, the Jasmine (Breath of Spring) necklace and Butterflies bracelet. “To keep a garden is to create, to care, and to hope,” Bunny Mellon once wrote. Seeing her philosophy, love of flowers and deep, abiding friendship come to life once again in this collection of high jewellery is a touching moment—even for those of us separated from her story by several decades and continents.
