Jewelry Designer Jenna Blake Opens Her Restored Bel Air Tudor Revival

There is a logic to the way Jenna Grosfeld lives. The Bel Air home she shares with her husband and three children is, by her own description, "an explosion of art, texture and color" — and so is the jewelry collection she sells under the name Jenna Blake. Both the house and the work reflect the same governing philosophy: that beauty is accumulated, layered, and made richer by knowing where things come from.

A 1936 Tudor Revival, Reclaimed

The house was built in 1936 by Gerald Kolkort, a well-regarded Los Angeles architect of the period, as an English Tudor. By the time Grosfeld and her husband acquired it in 2010, it had passed through so many owners that the original intention had been obscured entirely. "The house did not look like it had originally been intended," she says.

The renovation turned on a few decisive moves. What was originally the front door became a powder room. A small patio gate that once opened to the backyard became the new front entrance. "So really by just changing those two doors, we were able to change so much of the entry to the house," Grosfeld explains. The cumulative goal was to open the architecture up, to bring light into a style that can read as heavy and cloistered if left untended.

The dining room is the clearest expression of how Grosfeld thinks about a room. The table is a custom cut-glass piece, its surface bordered in bronze, built on vintage Art Deco bases. Around it sit Gustav Siegel chairs, their clean lines providing visual relief beneath the room's showstopper: a Venini chandelier that Grosfeld describes as "super ornate and heavy." The contrast is deliberate. "I love the boldness of the light fixture draped over the really clean, simple lines of the table and chairs," she says. A Barovier & Toso Murano-glass chandelier adds further presence elsewhere in the room, and a pair of matching Grosfeld House Regency-style buffets line the walls. Those sideboards carry particular significance: they were made by her husband's grandfather, part of a furniture line from the 1930s and '40s that later became highly collectible. The couple actively seeks out additional pieces. "It's a collection we've started ourselves and we have various Grosfeld House pieces throughout the house," she notes.

Two Sensibilities, One House

The renovation reflects a productive division of expertise. Her husband, the founder and chairman of Irongate, has developed landmark hospitality projects including the Four Seasons Los Cabos, the soon-to-open Amanvari in Costa Palmas, and the Ritz-Carlton Residences in Waikiki Beach. His instincts run toward structure and architecture. Grosfeld's run toward furniture and interiors, a disposition grounded in formal study: before launching her jewelry brand, she studied interior design in New York. "He and I both have a strong opinion and hand," she says. "He's more into the architecture. I'm more into the furniture and interiors."

That training turned out to be the foundation for everything that followed. "I discovered that jewelry was a way that I could take all of the things I was learning and implement them into my own creations," she says. "So it kind of became the perfect medium for me."

From Side Hustle to Wholesale

Grosfeld started her Jenna Blake business in 2014, selling privately through word of mouth and Instagram to her own Westside community. The entry pieces, diamond-edged shell pendants and gold bangles, became popular birthday, Mother's Day, and personal-treat gifts among her neighbors and friends. The business model was intimate by design: she knew her customers, understood what they wanted to wear, and built trust before she built infrastructure.

Over the past three years, that foundation has supported a more formal expansion. She launched e-commerce and moved into wholesale, picking up Neiman Marcus, Saks Fifth Avenue, Elyse Walker, Hirshleifers, and Broken English as accounts. Prices run from $1,500 to $50,000, a range broad enough to accommodate a first fringe necklace and a serious collector piece alike. One example of the latter category: an 18k yellow gold turquoise and blue sapphire three-stone ring, priced at $9,500. Celebrity clients have followed the brand into its broader moment; Rachel Brosnahan, Saoirse Ronan, Brandi Carlile, and Reese Witherspoon are among the names associated with the collection.

The Design Language: History in Layers

Grosfeld's aesthetic vocabulary is explicit about its sources. The collection draws inspiration from René Boivin, Boucheron, David Webb, and Ruser — a lineage that spans French mid-century sculptural jewelry, American maximalism, and the bold colorism of postwar design. The materials follow accordingly: natural diamonds, lapis, malachite, coral, and turquoise appear throughout, favored for their depth of color and their capacity to hold historical weight.

The product archetypes are just as deliberately referential. Trademark fringe necklaces recall the movement-forward pieces that French jewelers mastered in the early twentieth century. The 1960s mariner link chains and 1970s bar cuffs are period-specific in their proportions. Chunky stacking rings, crescents, enamel horns, and shell and charm pendants complete a vocabulary that rewards layering. A coral, emerald, and diamond "Gypsy" bangle worn alongside a Cartier Love bracelet; a turquoise and diamond fringe collar paired with new fringe earrings; a classic colorful mariner link chain over a bohemian beaded necklace. Each combination is intentional rather than accidental, building the kind of personal archive that takes years to curate.

"I've had the most success when people can see the collection in its entirety, and all the varying design elements that come together as one," Grosfeld says. "When you see the fringe and charms all in a cohesive way, it sells the pieces better, and entices people to want to know more about the story."

A Collector Steps Behind the Counter

The Couture Show in Las Vegas has long been part of Grosfeld's year. For many years she attended as a buyer, acquiring antique jewelry for her own collection. In 2026, she is participating for the first time as a retailer, presenting her keystone pieces to industry buyers who are now encountering the brand in its full scope rather than through a single retail account or a social media feed. The goal at Couture is the same one that has animated the business from its beginning: to show the work together, in context, so that the story of each piece is inseparable from the story of the collection as a whole.

It is the same instinct that guided the renovation of the Tudor Revival on the hill in Bel Air — the understanding that individual objects, however beautiful, mean more when you can see what they were designed to live alongside.
