Love the shape of the ring.

Abigail N.

• 3CT Round Cut Promise Ring

The shape won me over

I kept coming back to this ring because of the shape. Usually I end up choosing something very plain, so this was a nice change without feeling completely different from what I normally wear.

Alisha R.

A little outfit upgrade

Added the ring to a very basic outfit. Made such a difference.

Sienna W.
Verified Buyer

• 3CT Round Cut Promise Ring

A nice change

I usually choose the same kind of jewellery without thinking. The ring felt like a bit of a change, but not so different that I would struggle to put an outfit together.

Mia A.

• 3CT Round Cut Promise Ring

Wearing it on its own

Tried it beside my other rings but actually like it better on its own. You notice the design more.

Ella B.
Verified Buyer

• 3CT Round Cut Promise Ring

My favourite part

I especially like the shape of the ring.

Amelia C.

Just what I was after

The ring is lovely. Very me.

A new favourite

This ring has become my favourite part of getting ready.

Isla E.
Verified Buyer

• 3CT Round Cut Promise Ring

Worth a second look

Scrolled past at first, then came back to the ring. Glad I did. The design is much more my style than the other pieces I had been looking at.

Chloe F.
Verified Buyer

• 3CT Round Cut Promise Ring

Good, just a bit different

It's nice overall, just a little different from how I pictured it. Still happy with the design.

Grace G.
Verified Buyer

• 3CT Round Cut Promise Ring

Exactly my style

Not usually someone who changes their rings much. This one caught my eye and I can see why now. It goes with the bracelet I already wear, without looking like everything has to be a matching set.

Emily H.
Verified Buyer

• 3CT Round Cut Promise Ring

So nice

Love the ring.

Olivia J.
Verified Buyer

• 3CT Round Cut Promise Ring

The detail makes it

The overall design is nice. I noticed the shape of the ring first.

Lily K.
Verified Buyer

• 3CT Round Cut Promise Ring

Looks good in photos

Love how this ring looks in outfit photos.

Freya L.
Verified Buyer

• 3CT Round Cut Promise Ring

The design won me over

It was the shape of the ring that made me choose the ring.

Hannah M.
Verified Buyer

• 3CT Round Cut Promise Ring

Already a favourite

Been choosing the ring over some of my usual jewellery.

Zara N.
Verified Buyer

• 3CT Round Cut Promise Ring

Nice without being too much

The ring adds a bit of detail to my hand without the whole look feeling too busy.

Aisha P.
Verified Buyer

• 3CT Round Cut Promise Ring

A nice piece

I like the finish. It isn't exactly what I had in mind but still looks good.

Priya R.
Verified Buyer

• 3CT Round Cut Promise Ring

Good with more than one outfit

Tried the ring with something casual and then with a dressier outfit. I like it both ways. Nice to have jewellery that does not feel saved for just one occasion.

Jasmine S.
Verified Buyer

• 3CT Round Cut Promise Ring

Keeping the rest simple

Just this ring and a plain bracelet. Really like that combination.

Leah T.
Verified Buyer

• 3CT Round Cut Promise Ring

Really my style

The ring is exactly the sort of jewellery I reach for.

Nina W.
Verified Buyer

• 3CT Round Cut Promise Ring

Happy I chose it

Love the ring. The overall design is my favourite part.

Evie B.
Verified Buyer

• 3CT Round Cut Promise Ring

Glad I chose this one

Was between two rings for ages. Went with this one because I liked the overall shape more, and that is still my favourite thing about it. It looks good even when the rest of my outfit is really basic.

Ruby C.
Verified Buyer

• 3CT Round Cut Promise Ring

Happy with the choice

Spent a while choosing because I did not want more jewellery sitting in a drawer. I kept picturing the ring with outfits I actually wear. That is what helped me decide.

Poppy D.
Verified Buyer

• 3CT Round Cut Promise Ring

Love this ring

Such a nice ring. Looks lovely on.

Holly E.
Verified Buyer

• 3CT Round Cut Promise Ring

Good overall

Looks nice enough in person. I think I'd pick a slightly different style next time.

Lucy F.

Easy to add in

The ring works well with my usual jewellery.

Maya G.
Verified Buyer

• 3CT Round Cut Promise Ring

Better on my hand

Liked the photos, but I prefer how the ring looks on my hand. The shape is really nice.

Anika H.
Verified Buyer

• 3CT Round Cut Promise Ring

More dressed up

Put this ring on with my usual outfit and it instantly looked a bit more finished.
