Nova Drop Collection
When a nova ignites, it doesn't ask permission. It simply becomes — brilliant, fleeting, unforgettable. That's the energy we captured in every floating diamond.

The Nova Drop collection is built on a simple belief: fine jewelry should move with you, not weigh you down. Each piece in the system — from the foundational Aurea stud to the cascading Lumina threader — is designed to be worn alone or layered together, creating constellations as unique as the person wearing them.

Catch the light before it lands.

Aurea · Stilla · Lumina

Gold, light, and a single perfect drop — the elements of your constellation.

Aurea
Aurea

The Star Stud

In ancient Rome, the poets had a phrase: aurea aetas — the golden age. Not just an era of wealth, but of wholeness.

We named our star stud Aurea because it's the beginning of your personal golden age. Four points, perfectly balanced. Solid 14K gold, warm against the skin.

Aurea is the foundation. Wear it alone, and it's complete.

Aurea Nap
Aurea Nap

The Screw-Back Star

Stars don't sleep. But you should. Aurea Nap is the same four-pointed star, reimagined with a flat screw-back post that sits flush against the ear.

Designed for those who never want to take their stars off. Sleep in them. Shower in them. Live in them.

Stilla
Stilla

The Drop Alone · For Aurea

In Latin, stilla means a single drop — one perfect, suspended moment of liquid catching light before it falls.

A diamond held by a delicate gold ring that threads through the stone's drill hole — no prong, no setting, just the diamond itself, floating.

The drop alone. For Aurea. 2.5mm ring.

Stilla Stella
Stilla Stella

Drop + Star · For Hoops

When stilla meets stella — drop meets star — something new emerges. The Stilla Stella adds our signature four-pointed star bail above the diamond.

The 4mm ring slides onto hoops, huggies, and chains — anywhere you want a constellation to appear.

Drop + star. For hoops. 4mm ring.

Lumina
Lumina

The Threader

Light doesn't stay still. It threads through clouds, slips between leaves, traces its way across water.

Lumina is light made tangible. A fine gold chain that threads through your ear, carrying a diamond that catches and scatters every ray.

Sold as a pair. Brilliance in motion.
