Introducing Jillian’s Vault

A private collection for those who love jewelry with a story. Curated by Jillian, the vault features rare stones, unexpected details, and never-before-seen designs. Think a secret stash for true rock nerds.

From Jillian:

"Welcome to the vault! A special place where I can share new ideas that have been knocking around in my head and unique pieces with a small group of fellow jewelry enthusiasts and self-described rock nerds. It’s a place where there are no rules and I can share pieces right as they come off the bench.

When I started 10 years ago, I would share a “fresh ones” Friday on Instagram at the end of each week. I’d share all the pieces that had wrapped for the week. It was fun and loose and allowed for me to play and create and make mistakes and start over. I think that’s the feeling I’ve been chasing for the last year, soooo here we go. And I’m so happy that you’re here."

Take a sneak peek at what’s inside:

6.22ctw Boulder Opal & 0.22ctw Diamond Earrings

These playful-with-an-edge earrings feature 3mm round white diamonds at the stud, paired with elongated Australian Boulder Opals that glow with purplish-blue flashes. The abstract, organic silhouette and bold color of the opals contrasts beautifully with their 14k yellow gold abstract bezel setting, creating a striking, sculptural look that feels both effortless and elevated. Bold yet timeless, they catch the light with every movement, making them just as captivatingly worn casually as they are dressed up.

“This color reminds me of the sky at twilight, and I love that they’re not exactly the same. They’re organic and chunky and still pop even when your hair is down.” - Jillian

Styling Suggestion: Wear solo for a statement moment or pair with abstract bezel studs for added sparkle.

3.64ct Boulder Crystal Opal Ring

A dreamy 3.64ct Australian Boulder Crystal Opal set in 14k yellow gold, this ring is a small world of color all its own. The opal stone glows with vibrant green, blue, and yellow hues, shifting in a rolling flashfire pattern that feels alive as it moves through the light. Modern yet timeless, this piece is completely one-of-a-kind, designed to be the kind of ring you catch yourself staring at again and again.

“The play of color in this stone is incredible. As it shifts in the light, it’s totally mesmerizing. I found a handful of amazing opals in Tucson last year, and this one took me the better part of a year to design around. I’d wear her alone like a signet or stacked with a white gold dome ring.” - Jillian

Styling Suggestion: Stunning solo as a modern statement, or mix metals with a white gold dome ring.

3.89ct Opal and Rose Cut Diamond Pendant

A 3.89ct Lightning Ridge Crystal Opal sits in an abstract 14k gold bezel, its organic shape designed to follow the natural outline of the stone. Five rose-cut white diamonds accent one side, adding a subtle touch of sparkle without overwhelming the opal’s color. Suspended from an 18" Valentino chain, this asymmetrical pendant highlights the opal’s natural movement and soft flashes of pink, melon, and cool iridescence. The result is a modern, understated piece that still feels distinctly one-of-a-kind.

“The pops of pink and melon in this opal are truly mesmerizing. The abstract yellow gold bezel complements the stone so beautifully, and the rose-cut diamonds add just the right amount of shimmer. I’d layer her with gold chains or even a tennis necklace for a modern, effortless look.” -Jillian

Styling Suggestion: Layer with chains of varying lengths for a textured, modern stack, or pair it with the Juliette Opal Necklace for complementary opal and diamond accents.

3.62ct Old Mine Lab Created Diamond Ring

A 3.62ct Old Mine Cut Lab created diamond sits in a sculptural 14k yellow gold bezel cushion-modified brilliant facets catching light with a soft, romantic glow. Echoing the vintage-inspired silhouettes favored by icons like Taylor Swift, this piece blends old-world charm with contemporary refinement, bringing together the warm nostalgia of antique cuts with a clean, modern silhouette. Finished with a quiet sense of sophistication, it becomes a timeless statement - refined, distinctive, and effortlessly one-of-a-kind.

“Our newest engagement ring style! I love the extra chunky bezel, exposed culet and that you can stack her with a straight band! The cut of this lab grown diamond is very similar to the cut of Taylor Swift's engagement ring. We found this right before she got engaged and I haven't found another one since! It's an absolutely gorgeous cut.” - Jillian

Styling Suggestion: Layer with the Lucy Wave stacking band for a beautifully sculptural effect.
