Kosinerjewelry Reviews 

Jewelry is cheap. I doubt it is actually 925 silver.
Service is horrible as well. I wanted to return the pieces because the quality feels low. They adviced me to give tje jewellery to a friend because returning would be to expensive. As 'compensation' they would give me 20% of my next order. Which is funny, because there was already a coupon in my delivery for 20% of at my next order for loyal costumers.

Excellent customer service, quality of jewellery was amazing and they responded very quickly to my queries.

Couldn’t get the earring on because it had a big flat circle that wouldn’t go through my ear. The company states on their website that it’s 30 day return but when I email about it they said wouldn’t accept it. Told me to gift it to someone because if I return it I will pay expensive postage and customs charges then they broke off the contract.

Brought what I thought was a pair of butterfly earrings but was only 1. I have contacted customer services and they have instantly dealt with issue. Very prompt and im very satisfied with the outcome. Highly recommend

Great customer service.

I had a query about my order. Received a fast response via Instagram messaging. Customer service team were polite and helpful. Resolved my issue. :)

I recommend, i have an issue with an order but they replied me so fast and solved the problem

This company is a scam!! They are not based in Hong Kong and send the wrong cheap products. Customer Service does not exist. This is a fake company and product. BUYERS BEWARE!!!

Nice jewelery and great service!

I do not recommend! Especially the hoop earrings, they are not staying closed and the part that goes through your ear is so thin that is bending easily.
It’s not worth the price at all!

I had an issue with my order at first, but the customer service team at Kosiner Jewelry handled it very professionally. They carefully reviewed my case, approved the return, and processed a full refund without any problems.

What impressed me most was that, despite the initial difficulties, they eventually went above and beyond to make things right. This shows they truly care about customer satisfaction.

Thank you for resolving my situation — I really appreciate the support and fairness.

Amazing service I love kosinerjewelry I love all their pieces. I’ve purchased about 7 times now and bought 14k gold pieces and the quality is amazing and they are absolutely beautiful. Will always purchase from here.

So far not impressed. The earing arrived in a lovely packaging however it's so so tiny I cannot even handle it plus nowhere that it says it made of white gold. I emailed a few days ago but heard nothing so far..

I love the products, collected a few 14k earrings now, as well as a handy tool which makes insertion and fixing the front of the earring very easy process.
Always quick delivery to the UK, and we'll packed to include product pouch, box and gift bag.

Kosiner jewelry is of exceptional quality, and I’ve worn them for years without ever taking them off. The colors and shine are still perfectly preserved, making it one of my favorite jewelry brands.

“I love their jewelry, I even wear it in the shower and it has never been damaged. Besides being beautiful, it’s also very durable

Great range of products, little price.
Love the quality is amazing, the earrings are my favorite.
Always buying from kosiner, really recommend

The best products ever! They are beautiful, versatile, and incredible pieces of jewelry. Their quality is fantastic—I’ve had mine for years and they still look brand new. They’re water-resistant, durable, absolutely stunning, and always make a great impression. I’ve always received so many compliments on them.

I bought a 14k white gold piercing 2 month ago and I‘m wearing it ever since! Shipping and delivery was fast! Packaging so nicely done and the piercing itself is so beautiful and sparkly! Will definitely order more👍🏻

I have purchased from both their 14k gold and ‘regular’ collection. Both extremely pretty. The regular item (a necklace) looks good but does not seem to be of extremely good quality- however, as I only paid about £15 I do not expect it to last decades. It is a very pretty, lovely accessory.
However, the 14k gold range was a pleasant surprise- it is real gold and is very well made. I got a stud earring with lab diamond and love it. Definitely a real deal, I have compared it to my diamond ring. I will definitely purchase from them in the future.

KS24759 Jewelry has fallen out of earring and havent had them long. Customer service was very slow, id emailed, messaged on chat from website and instagram. I even posted a comment on their post and they deleted it.
