Words from our Customers
Still shines like day one
★★★★★
Three months wearing it non-stop, shower, gym, beach and it hasn't lost a bit of color. Best jewelry I've owned.
— Claire
Perfect gift, beautiful packaging
★★★★★
Bought it for my sister's birthday and the unboxing felt so special. She hasn't taken it off since.
— Laura
Light, comfy and zero irritation
★★★★★
I have super sensitive skin and this is the first necklace that leaves no marks. I forget I'm even wearing it.
— Andrea
Somewhere between a mooring rope and the tide line, a chain earns its weight. This one changes character halfway along, flat curb links giving way to rounded ones, and closes at the front through a crystal-set bar.
Two link styles in one chain: flat curb along one half, chunkier rounded links along the other
Fastens at the front with a T-bar, a small crystal held in a bezel at its centre
Stainless steel finished with 18K gold plating
Main stone: crystal in a bezel setting
Substantial enough to wear on its own, with the clasp deliberately left on show
Waterproof and sweatproof, so there is no need to take it off for the heat or the sea
Lead-free and hypoallergenic, kind to skin that reacts easily
Arrives in eco-friendly packaging with a pack of stickers

Went with everything
Genuinely, the Thalassa chain is so much prettier in person than in the photos. Still as new after three months of daily wear. It punches way above its price. Would make a great gift, comes in nice packaging. I read a load of reviews before buying and they were right. Keeper.

At last found it
It's the kind of thing you can just leave on. Lovely holiday piece, works with a tan. Shipping was speedy, turned up a couple of days later. Very happy with it.

Comfortable closure
I have compared it next to a much pricier chain and the difference is genuinely hard to spot. The chain drop suits my crew neck and the pendant rests mid chest rather than disappearing. Bought the chain for a summer party; it did the job with a white shirt. The concern had been whether the chain might look cheap up close. It does not.

Cutest necklace ever!
OMG, the Thalassa necklace is so pretty!! Honestly the most beautiful thing I have! Wearing it with a plain white tee and then with a little black dress later on and it looked right for both. Would certainly buy again ✨

Perfect daily necklace
Wore this one to a 21st in July and my book club wanted to know where I got it. Big fan of the chunky shape, it's honestly what makes the necklace look a bit different. It looks properly elegant when it's on, even with zero effort. I gave it to my mother on a 21st and she showed everyone at the table. Happy with this necklace!

Pretty but never OTT
So I hesitated about the Thalassa necklace for weeks and I've no idea why. It has that sort of heirloom-y vibe without feeling old. Was properly nervous buying jewelry off a website but it was worth the gamble. The receptionist at work complimented it, which never happens. Came in such cute packaging, felt like a proper gift. Do recommend, especially for the price. PS the packaging is so nice

A little smaller than expected
Good value for what you get. Fair value for the finish. Will continue wearing it.

The chain hasn't tangled
This one is a go-to wear now. Suits both plain and patterned pieces, which means I never need to think about it. The length is as described and hangs well on my usual necklines.

Nice chain, sits well.

Holiday essential
Okay, the chain is very pretty. I basically leave it on so it goes with the day's outfit. For the money it's hard to beat, honestly. Was a bit sceptical ordering jewellery without seeing it but it was worth the gamble. It will become one of those pieces I put on without thinking.

loving this
this necklace is somewhat daintier than i pictured, but that turned out to be a good thing. no irritation so far, which for me is rare. it attracts comments every time i wear it. prompt delivery and nicely packaged.

Birthday present for my daughter
Got this necklace to go with my daughter's bridesmaid dress and it was exactly right on the day. Not too flashy, which is what I wanted. The chain feels delicate but nowhere near weak, and it hasn't kinked or knotted. Ordered it last minute for a wedding and it actually arrived with a day to spare!

I bought it for my roommate and she was absolutely delighted with it. It has a timeless look that suits both day and evening occasions. I could not be more pleased.

Good finish for the price, and prompt delivery. It sits where it should and doesn't require readjusting. Works for work and also evenings.

Zero tarnish yet
This is my first purchase from this shop and it went well. Easy to style: it dresses up for a dress but behaves with a t-shirt.

Got after seeing it on a friend
Took this chain on a beach trip in May and wore it every single day. Size-wise it's exactly as described. Wore the chain for a 21st with a blazer and honestly it pulled together the entire look. Going to make a lovely gift, packaging is spot on for it. I've already sent the link to four colleagues.

Julia Martin
Lovely little thing
Fun fact: I bought this chain in a hotel room and it was a great purchase of the summer. Light enough to the point I sleep in it. The chunky shape was the detail that made me stop scrolling in the first place. Goes with pretty much everything, I've tested this thoroughly. I had been let down by a small jewellery shop before, so it was a pleasant surprise! Thanks all.
