Suite à mon précédent commentaire, je tiens à souligner le professionnalisme et la qualité du service après-vente. Malgré ma déception initiale, l’entreprise a su prendre en compte mon mécontentement avec sérieux, respect et compréhension. Le service client a été à l’écoute, réactif et compréhensif, et une solution a finalement été trouvée.
Je tiens donc à saluer leur manière de gérer la situation et leur sérieux dans le traitement de ma réclamation. Il est important de souligner également les expériences positives, et je remercie le service après-vente pour son professionnalisme et son respect envers ses clients. Une expérience qui se termine finalement sur une note positive !

I ordered a stud which I thought would have been a pair. The product was also smaller than what I thought it would be. When contacting customer service, they offered to rectify the situation which was great. I just wish the picture on their site would have shown a more an exact size.

Very poor customer service experience
Edit to my review: customer service reached out to me and solved my issue. Thank you!
Very poor customer service experience. I ordered two items and just a few minutes after ordering I realised that I forgot to add another item. I did not want to place a new order for it as the shipping costs to Europe are quite high and you also get an extra discount if you buy three items. On their website it states that if you want to make changes to an existing order or add an item, you should contact customer service immediately. And that’s what I did. I contacted them a few minutes after placing the order. 2(!) days later I get a response to say that my order has already shipped and that no changes can be made to the order. They didnt even apologise for responding so late or at least offer to waive the shipping costs for the other item. Completely misleading information and wouldn’t order again!

Dear Nina,
Thank you for taking the time to share your feedback, and please accept our sincerest apologies for the frustration you've experienced. We completely understand why you're upset, and we truly regret that our response came two days later – that was not up to our standard, and we should have done better.
To be transparent with you, the delay in our reply was due to the way our customer service system prioritises emails: we respond to the oldest unresolved tickets first. When you sent additional follow-up emails, your thread was automatically pushed to the top as a "new" activity, which unfortunately moved it to the back of the queue each time. As a result, we didn't get to your case as quickly as we should have. We sincerely apologise for this oversight and are already reviewing our workflow to prevent this from happening again.
We also want to explain that our warehouse ships in-stock orders immediately upon placement in order to get every customer's package to them as quickly as possible. In your case, because your order was processed and shipped promptly, we were unfortunately unable to make changes or combine items after the fact.
That said, we hear your concerns, and we'd like to make things right for you.
We are reaching out to you directly to confirm this arrangement, and we truly hope this resolution shows you that we value you as a customer. We are taking your feedback seriously and will work to improve our response time going forward.
Please let us know if this works for you – we're here to help.
Best regards,
Kosiner Jewelry Team

Updated review: great customer service
Revising my initial review!! I was emailed by Nicole who issued a refund. Even suggested keeping the jewelry once I receive it but it is still the wrong size but who knows? Maybe it will work for someone else. Very happy with the customer service here and changing my review. I do wish the policy allowed for returns of fine jewelry in packaging and unused.

HI AP PNW,
Thank you for sharing your experience, and I'm very sorry for the frustration this has caused you.
Could you please provide me with your order number? I'd like to look into this for you right away.
To clarify, if the product is unused and in its original packaging, it is eligible for return. I apologize if this wasn't made clear during the checkout process. Please allow me to check your order details so I can help resolve this for you.
I look forward to your reply so we can make things right.
Best regards,

Not a happy experience
Order# KS45459
Bought a pair of Open Huggies earrings on the site a week ago.
I was very disappointed on receiving the items as they are far too small/tiny to even hold down to, let alone to put them in my helix pieces.
I request a return authorisation on the ground of not made fit for purpose.
Then you get those lengthy justifications of no faulty on the produc and suggestions with discounts, give them to friends, etc, to refuse for a returning and refund.
It’s been a disappointing, stressful and frustrating experience.
They don’t seem to understand UK remote/online shopping and consumer laws/rights about that the products have to be fit for purposes and consumers’ rights to cancel/return the order within 14 days if not satisfied.
Amendment : 05/02/2026
After a few back forth emails, we’ve reached a mutual agreement that they given me a full refund and let me keep the product.
I’m pleased that they are working on their Customer Service and I think every one deserves a second chance to be excellent.

Customer Service Satisfaction
I had submitted a negative review regarding Kosiner's customer service on a Christmas purchase that my wife could not (due to sever arthritis in her hands) properly use in her pierced ears. Since posting that, Kosiner has indicated they will now fully credit my account which I do greatly appreciate. I know the products they offer are of fine quality and I suggest those wishing to enhance their ear styles utilize Kosiners wide array of ear enhancements.My thanks to Kosiner for their assistance in remediting this issue to both our satisfaction.,

I bought three earrings from kosiner
I bought three earrings from kosiner. Two seem good and excellent for the price (although I've only had the earrings for a couple weeks so can't say if they'll tarnish or are proper 14k gold as sold). The third earring, the colour was completely different to the advert. It was a bit of a struggle to get a refund, as I had to go through several "no but here's another offer"s to get there, but in the end I got a full refund.
Overall, the price seems good (pending longevity) and they refunded me for the poor quality product. So would recommend

Hi Antonia,
Thank you for taking the time to share your experience with us and for your honest feedback.
We’re glad to hear that two of the earrings met your expectations in terms of quality and value. We’re also sorry that one item did not match the advertised color and caused frustration during the refund process — this is certainly not the experience we aim to provide.
We appreciate your patience while our team worked to resolve the issue, and we’re pleased that a full refund was issued for the item that did not meet our standards. Your feedback is valuable to us and helps us continue improving both our product quality and customer support.
Thank you again for giving Kosiner a try, and we truly appreciate your recommendation.
Kind regards,
The Kosiner Jewelry Customer Support Team
