Good but needs lots of improvement
Good: Delivery is quick and packaging is beautiful. They are pretty and shiny.
Could improve: The length of the earrings are too long for lobe piercings as well as some cartílago piercings. It is also disappointing that the earrings are not flat backs. There is no 14K stamp which may potentially mean they are not... but time will tell

Thank you for your review and feedback! We're so glad to hear that you're happy with the product's appearance, packaging, and shipping speed. We also truly appreciate your suggestions regarding the earring length and the earring backs—this kind of feedback is very helpful as we continue to improve our designs.
Regarding the 14K stamp you mentioned, we'd like to assure you that we have strict quality control measures in place, and each earring post is clearly stamped with “14K” at the bottom, exactly as shown in our product images. Since the post is quite small, the stamp may not be immediately visible. We recommend checking under good lighting for a closer look.
Additionally, all our 14K gold jewelry comes with a 2-year quality guarantee. If there is any non‑damage‑related issue during this period, we offer free replacement or a full refund—so you can wear your pieces with confidence.
If you have any further questions or need assistance, please don’t hesitate to reach out to our customer service team at [email protected]. We truly value your honest feedback, as it helps us serve you better.

Absolutely love Kosiner Jewelry
Absolutely love Kosiner Jewelry! I've actually got a collection of their solid gold piercings and I love that they're affordable considering that they're solid gold, have unique designs and are very comfortable on the ears. Shipping was very quick and packaged really nicely. I highly recommend Kosiner Jewelry and will definitely be a returning customer.

Great selection of earrings
Great selection of earrings! I couldn't find a pair that was small and delicate enough and finally found the perfect pair on Kosiner. I have very sensitive ears and their selection of Titanium earrings has been amazing for me. Their customer service is also very responsive and helpful.

Perfect experience
Hello ✨
I just wanted to share some very positive feedback about my order. I purchased a lab-grown diamond earring in 14-karat gold, and I’m absolutely thrilled with it!
I’m allergic to any material other than gold, so I always have to be very careful with what I buy — and I had been looking for exactly this kind of earring for such a long time. I wanted something really small for my third lobe piercing (which I only have on one side), and the fact that you allow customers to buy a single earring is just amazing! As a French customer, I had never heard of your brand before, and to be honest, at first I was a bit worried that your website might not be genuine.
I’m so glad I decided to place the order — the piece is beautiful, the quality is excellent, and it’s exactly what I was hoping for. Thank you for your professionalism and the quality of your jewelry! 🤍🤍

Hi Elodie,
Thank you so much for taking the time to share such a thoughtful and detailed review ✨
We’re absolutely delighted to hear that you love your lab-grown diamond earring and that it was exactly what you were looking for.
We understand how important material choice is, especially for customers with allergies, so it truly means a lot to know that the 14K gold worked perfectly for you. We’re also glad you appreciated the option to purchase a single earring — it’s something we offer specifically to support individual piercing needs.
As a first-time customer, your trust is incredibly important to us, and we’re so happy that your experience reassured you. Thank you for your kind words about our craftsmanship and professionalism.
We hope your piece brings you joy every day, and we look forward to welcoming you back again in the future 💛
Warm regards,
The Kosiner Jewelry Customer Support Team

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
