A Modest Marvel for Your Ears

Admittedly, we may not be jewellery moguls or red carpet regulars, but we've stumbled into something rather fetching here. These Black Onyx Cube Earrings are a glorious nod to understated flair — just the thing for the discerning ear in search of a mildly glamorous upgrade. Subtle? Yes. But fabulously made? Absolutely.

Why Choose Our Black Onyx Cube Earrings?

Geometric Chic: The black onyx cube adds a whisper of edge to your look, without shouting down the rest of your outfit.
Two Gorgeous Finishes: Opt for rose gold if you’re feeling romantic, silver if you’re into the classics. Or both because why not?
Crafted in Sterling Silver: We’re talking proper 925 sterling silver, so no green ears — only a properly handsome shine.
Wearable Every Day: Designed to go with everything from your Tuesday grocery run to your Friday dinner-that’s-a-bit-fancy.

Product Details:

Materials: 925 Sterling Silver and Black Onyx
Design Origin: Conceived in Estonia, which frankly feels exotic and cultured, don’t you think?

Whether you're indulging a flair for curated simplicity or shopping for someone terribly hard to impress, these earrings are delightfully stylish and rather good. Pick up a pair now before the universe realises how fabulous they are.

THE RATHER IMPORTANT BITS

This rather lovely piece ships directly from our brand partner - we work with independent brands who are absolutely brilliant and work frightfully hard to create beautiful things.

SHIPPING DESTINATIONS
Now, here's the thing - our wonderful brand partners ship to lots of different places, but not all of them can ship worldwide.

Some are brilliant at international shipping, others prefer to keep things closer to home.

At checkout, you'll see exactly where this particular brand can send your goodies.

We're terribly sorry, but shipping costs do vary rather wildly depending on where you are in the world. The exact figures pop up at checkout - no nasty surprises!

RETURNS

You have 14 days to return items.

Now, we absolutely adore our brand partners - they work incredibly hard and we do try to support them as much as we possibly can. So I'm rather afraid we have to pass the return postage costs back to you. Frightfully sorry about that!

🌍 PLEASE CHOOSE THOUGHTFULLY:
Our wonderful partners put their hearts into everything they make.

Ordering multiple sizes to try at home is rather hard on our planet and makes things jolly difficult for these brilliant independent creators.
When in doubt, do ask us first!
The brands we work with all have a chat option, and they love to chat!

We're frightfully modern and accept all the usual suspects:

Visa, Mastercard, American Express, PayPal, Apple Pay, Google Pay, and Shop Pay

SECURE AS HOUSES
Everything's properly encrypted and secure - your details are safer than the Crown Jewels!

All prices in lovely British pounds £ GBP, though international chaps will see converted prices.

Any payment pickle? We're here to help sort things out! Contact us

We are Sostter

We met as children. Grew up a few streets apart. Built dens, rode bikes, and eventually — built Sostter.
It started with a shared love of objects that meant something…things with a past, or at least a purpose.
Now, Sostter is our grown-up version of a treasure hunt: a space where design meets storytelling.
We curate independent brands, one-of-a-kind finds, and everyday essentials with character.

We’re proud to support Sutton Night Watch, a grassroots UK charity making a real difference in the lives of those facing homelessness. Through regular donations of stock, supplies, and essentials, we back their mission to offer warmth, dignity, and practical help to anyone in need — right where it matters most.

Sostter partners with independent brands that intrigue, inspire, and bring something genuinely different to the world of fashion, design, and living. Join us!
