The Nova Drop System
Style Your Own Nova Drop Looks
Begin with Aurea. Add a Stilla charm. Thread Lumina through. Every combination tells a different story.
The Collection
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.
The Story Behind Each Piece
Aurea · Stilla · Lumina
Gold, light, and a single perfect drop — the elements of your constellation.
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.
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.
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.
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.
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.
Our Promise
The Lab Diamond Difference
Lab Grown Diamond Earrings — The Nova Drop Collection
Nova Drop is Cosmo Carat's signature lab grown diamond earring collection, crafted in 14K solid gold. Every piece features a certified lab created diamond — identical in brilliance, hardness, and fire to mined stones, at a fraction of the environmental cost. Our modular system lets you mix and match diamond stud earrings, floating diamond charms, and diamond threader earrings to create your own curated ear stack.
Choose from over 20 diamond shapes — round brilliant, oval, pear, emerald cut, and marquise — in three gold tones: yellow gold, white gold, and rose gold. Available in 0.3ct, 0.5ct, and 1 carat weights. The Aurea star stud is our flatback earring with a screw-back option perfect for nap earrings and everyday wear. Add a Stilla floating diamond charm to transform your look, or wear the Lumina diamond threader earring for effortless elegance.
Lab grown diamond jewelry doesn't mean compromise — it means smarter luxury. Each Nova Drop diamond is ethically made, conflict-free, and traceable from lab to your jewelry box. Fine diamond earrings for women who want beauty with intention.
