Quiet, grounded, one-of-a-kind. This onyx is hand-set in polished 925 sterling silver — small variations in colour and veining are part of what makes it real.

Why it's special
Reconstituted onyx gives the mineral’s true colour without the flaws a natural slab hides. We set every stone by hand in sterling silver, so the focus stays on the stone itself.
Care
Hand-polished and tarnish-resistant. Avoid contact with perfume, lotion, and chlorinated water. Wipe with a soft cloth after wear and store in the jewelry box it ships in.

Earring size & fit
How stone sizes look on the ear, which closures we use, and how to wear earrings comfortably all day.
Stone size on the ear
| Stone | Diameter | How it reads |
|---|---|---|
| 0.5 Ct | ≈ 5.2 mm | Subtle everyday sparkle |
| 1.0 Ct | ≈ 6.5 mm | Noticeable — the classic stud size |
| 2.0 Ct | ≈ 8.2 mm | Statement, catches light across the room |
For hoops and huggies: 10–14 mm hugs the earlobe, 15–25 mm is a classic hoop, 30 mm+ is a statement. The diameter is listed on each product page.
Closure types
- Friction push back — the classic stud closure: slides on, holds firmly, easy on and off.
- Screw back — twists onto a threaded post; the most secure option, great for sleeping in or for valuable stones.
- Hinged huggie latch — clicks shut around the lobe; no separate back to lose.
- Lever / English back — for drop earrings: the lever locks behind the lobe and keeps the earring hanging straight.
Comfort & care
- Hypoallergenic by default. All our posts are 925 sterling silver, rhodium-plated and nickel-free — safe for sensitive ears.
- Weight matters. Under ~2 g per earring feels weightless all day; heavier drops are best for occasions.
- Keep the sparkle. Take earrings off before showering and sleeping, wipe with a soft cloth after wear.
