Honestly, I thought it might look cheaper in person, but it doesn't. The details are actually quite clean and well done. It came in good condition and nothing was damaged during shipping, which I appreciated.

I purchased my first pair of earrings, and I must say that I fell in love with them. They are truly beautiful. I would recommend this brand. I'll definitely be purchasing more in the future.

I really like the jewelry. It’s very quality. I lost a piece and immediately came back to re-order. I had to utilize customer service once and they were responsive, happy to help, & quick to do so!

I had a wonderful experience with Kosiner Jewelry! Their customer service team was extremely kind, responsive, and helpful throughout the entire process. They handled my exchange request quickly and professionally, and I truly appreciate their generosity and support.
The jewelry is beautiful, high quality, and exactly as described. It’s rare to find a company that genuinely cares about customer satisfaction the way Kosiner does.
Highly recommend Kosiner Jewelry to anyone looking for elegant pieces and excellent service!

Received my jewellery after some problems with delivery (nothing to do with Kosiner), it's beautiful and well made, very impressed.
Great products came as described. Customer service was very helpful.
I got help from their costumer service to get a matching pair of earrings, when I accidentally just bought one piece
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.

Absolutely beautiful solid gold earrings + outstanding customer service from Kosirier Jewelry!
I was looking for earrings for my 1.5 year old daughter and I'm so happy I found Kosirier Jewelry. It's so hard to find real solid gold flat back earrings in the right size for babies - most places only have plated ones or regular backs that aren't safe. But Kosirier has them, and they're absolutely beautiful!
The earrings are delicate, perfectly sized for a toddler, and the quality is amazing. I love that they're solid gold, so I don't have to worry about allergies or her sensitive skin. The flat back design is exactly what I wanted - comfortable and safe for her to sleep in. Plus they have so many cute designs to choose from, it was hard to pick just one!
The packaging was also beautiful. They arrived in an elegant little jewelry box with soft padding, wrapped really nicely. It felt like a proper gift, perfect for her first earrings.
I did have a small issue with my order, but their customer service team was incredible. They replied to my email in few days, were so kind and professional, and arrange a free replacement shipment.
As a mum, finding safe, high-quality, solid gold jewelry for babies is a nightmare, so I'm really grateful for Kosirier Jewelry. Thank you for making my daughter's first earrings such a special experience. I'll definitely be back to shop the other cute models you have for me as well :) as I have sensitive skin too!

Issues with customer service. I contacted them 10-15 min after I placed my order to cancel it as I realized that the piercing I was trying to purchase was not actually solid 14k gold as the post is titanium (although it was listed as 14k gold in materials and title, and the only mention of a titanium post was at the bottom in the description). I also tried using the live chat but was never able to get through to a customer service representative despite it being business hours. I received an email <12h later saying that they will not refund my purchase and had shipped it out. Their website says explicitly to contact them within 24h to cancel orders but it seems like that’s actually not the case. Very upsetting/disappointing experience!
Update: after A LOT of back and forth with the company, they are refunding me and letting me keep the package as it had already been shipped. Therefore, amending my review to 3 stars given that they did try to rectify their mistake.

Do not order with this company!! I placed an order over 400,- euros to Europe and they refuse to take returns due to problems with their warehouse in China, high shipping costs and custom fees. Nowhere on the website or in their return policies have they made any mention of this and I've already read many bad reviews on numerous platforms mentioning the same issue. Completely unlawfull, they are scamming people. I am currently exploring options to take legal action because this is absolutely isane.

I purchased this earring specifically for my conch piercing, but unfortunately, it has been a painful experience. Despite following standard aftercare, the jewelry caused significant irritation and inflammation within a short period of wearing it.
Issues Encountered:
• Material Quality: The metal seems to be reactive. Even though it was marketed for piercings, my ear reacted as if it were a low-grade alloy or contained nickel.
• Physical Discomfort: The inflammation became so severe that I had to remove the jewelry entirely to prevent further infection or permanent damage to the cartilage.

Purchased several solid gold piercings and was really impressed. They even include helpful attachments that make putting them in much easier (anyone with piercings knows how frustrating it can be trying to thread them from the back of the ear). The quality is excellent, and I’m very happy with my purchase.

These earrings are beautiful and such great quality for the price. The 14K gold plating over sterling silver looks really polished and expensive, and they're lightweight and comfortable enough to wear all day. I have sensitive ears and had no irritation at all. They've held up well with regular wear and still look shiny. Perfect for everyday or dressing up - definitely a great jewelry staple.

Excellent resolution to a problem I encountered. Great service, great products. Delivered promptly, well packaged.

The jewelry I ordered was delicate, full of sparkle and high quality. I made an error estimating sizing and customer service went above and beyond in their assistance. Items arrived quickly and with tools for changing jewelry included. I’m very impressed with this company and I will definitely continue to order from them.
