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
The last of the light catches on the water and stays there a second before it goes. This small heart-cut stone works the same way — one quiet flash, worn close to the skin.

Perfect length
Properly obsessed with the pendant 😍 The heart is so cute, but not in a childish way.

Comfortable fit
Bought the Tideline Heart-Cut Bezel Necklace for a garden party. Did the job with a simple vest top. Bought it for a garden party; it looked right with a summer dress. Good value for the quality.

Elegant and beautifully made
I have received many admiring comments on my new necklace since it arrived. Still like new after over a month of daily wear. The setting is neatly finished and gives it a distinctive character. Most impressed all round.

Everyday wear
Good weight for the price, plus fast delivery. My grandma has been wearing it to work since her birthday. All fine.

Lovely find
This one is chef's kiss! Not too shiny, which is what I wanted. The pendant!! Love this! Works with literally everything! Day, weekend, beach, all of it. I've already bookmarked three more pieces on my wishlist, which is dangerous. Just buy it.

Georgia Gray
Summer staple
Had the necklace on for the first time properly yesterday and everyone asked about it. It looks way more high end than it should for the price. Had 5 compliments already. No regrets, would do it again.

Definite keeper
Little review because I think this necklace deserves it. Love the heart, it's the reason I chose it. Would definitely recommend.

Look pricier than it is
Pretty little necklace, just what I wanted. Big fan of the pendant, it's the thing that makes this necklace feel slightly different. 😍

Phoebe Baker
Second order, all happy
The pendant is one of those pieces you can just leave on. Goes with pretty much everything. Could've easily paid double on something looking like this.

Ava Powell
My Tideline pendant!
Happy customer here. This pendant is just as shown. It has that kind of vintage feel without looking costume-y. Made for the summer: cool. Had it to a 30th and the girl doing my nails asked where it was from, then someone else asked too an hour later. I'll be ordering more soon. PS it arrived a day early, nice surprise.

Valeria Sanders
Okay I get the hype now
Right, I wasn't sure about my new pendant for ages and I've no idea why. Easy to wear: it dresses up for an occasion and sits back with a t-shirt. Solid 10/10, no notes
C
Celia Mills
Adore this
The necklace is somewhat daintier than I expected, but I actually prefer it. The pics actually undersell it, there's more detail in person. Featherlight but somehow feels solid. Treat yourself to one, honestly! 💛
L
Leah Bailey
No tarnish so far
The size: the necklace is pretty much what the listing says, so look at the numbers rather than guessing. It gets compliments nearly every time I wear it. Have ordered from here before and this is consistent. Well worth it.
G
Georgia Ward
Little treat to myself
Can't stop staring at this one, is that weird? The setting was the detail that made me stop scrolling originally. Looked even better with a tan.
M
Megan Perry
Would happily order again
The Tideline Heart-Cut Bezel Necklace looks as described and wears nicely. Perfect holiday piece, light and easy. The question had been if it might look flimsy in person, and it does not. I'd buy again.

Will buy again
Arrived in three days. It gets noticed far more than you'd think, considering the size.

LOVE LOVE love!!
I not taking this pendant off. Sorry. Was a bit wary ordering jewelry without seeing it but it put my mind at rest.

Will order again
It is a go-to piece now. Goes with the office as well as smarter occasions.

Came fast, nicely packed and the pendant looks the same as the photos. I read the reviews before buying and they were accurate, thankfully! Wear it right now.

everything perfect
it is smaller than i thought but really nice.

Leah Taylor
Well worth it
I have worn the Tideline necklace to work and it has held up well. The heart is crisply defined, with none of the mushy detail you sometimes get at this price. Wasn't sure about the listing but the necklace is more substantial in the hand. Would happily buy from this shop again. A great purchase.
M
Megan Baker
nice necklace
this necklace is really nice on, and i recommend it. for size it's exactly as listed, so measure first if you're unsure. it gets attention nearly every time i wear it. 5 stars.

Nicole Morgan
Nicely made
Got this necklace after losing something similar and it has filled the gap. Length was as listed and sits where I wanted with most necklines. Would recommend without hesitation.

Naomi Davies
Went with everything
Genuinely, it's even nicer in person than online!! Its finish is really clean, zero weird seams. Looked even better with a tan, not that I'm showing off. Suits literally everything, I've tried! Shipping took a bit longer than I'd hoped, but the necklace was perfect and I'm not fussed. This is my second purchase from this shop and it's never missed yet. Would recommend, especially for the price.

Eleanor Bell
Repeat order
This is my first purchase from here and I'm pleased. The setting feels secure and has not given me any trouble. No skin reaction as yet, which I sometimes get. Worth the money.
L
Lily Price
Pleased with this
The necklace is a good wear-anywhere piece. Understated for work but with a bit of sparkle to notice. Sizing it's exactly what the measurements say, so measure first if you're unsure. If I'm honest, picky, the clasp took a bit of getting used to, that's all. Does the job well.
C
Clara Phillips
Simple but well made
Some notes for anyone thinking about it. I have been fairly unkind with this pendant (sea, sun cream, hand gel) and it's holding up as new. Pricing is reasonable given the finish. Will be ordering more in the same finish.
C
Charlotte Turner
Holding up well
Good necklace. Came within 48 hours, no issues. The heart is a sweet detail that makes it feel less generic. Have had several comments from friends. Packaging was neat and protective; nothing was damaged. I have ordered from this shop before and this was just as good. Pleased I bought it.

Lucia Williams
Get it
Second piece I've bought from here and still not disappointed. I basically keep it on so it goes with whatever I've thrown on. Had it on for a first date! So good. Not a bad word to say, really. 👌

Leah Bishop
A bit smaller than expected, but lovely
Good value for what you get. Packaging was decent and sturdy; nothing was damaged.
N
Nicole Brooks
A yes from me
I had been looking at the Tideline pendant for a good while before eventually ordering, and I'm so glad I did. The heart has a story behind it, so it was an especially personal gift. Delivery was quick, here in three working days, nicely packed too. Massively recommend!
