I bought a 14K gold/lab grown diamond stud for my helix piercing. It delivered a week after purchase, and was beautiful. I realized that the post length I chose was too long so I reached out to the company to request an exchange. They got back to me within 48 hours and graciously offered to replace the post with a smaller one free of charge. Great product, great customer service!

I ordered a pair of titanium earrings from Kosiner for my wife. The product was high quality, but the size I selected was smaller than I expected. Their customer service has been fantastic at getting me what I need, even though there was no error on their part. Highly recommended for the quality product and excellent customer support.

May 23: Order made but unshipped May 28: Email enquiry about my order May 29: They confirmed order would be shipped Jun 1 so I agreed not to cancel for a refund Jun 2: No order progress or tracking provided, emailed to cancel within their terms - no reply Jun 3: Emailed again - no reply Jun 4: Left an angry comment on their IG post and raised a chargeback Jun 5: Refunded Seems like this company isn’t serious about actually shipping their customers’ orders or replying to issues. Very disappointing experience as I spent $300+ on an order and they didn’t even have the courtesy of sending an email to let me know the status or my order.

Thank you for your sincere feedback. We completely understand your disappointment, and we truly apologize. We promised your order would ship on June 1st. We not only failed to ship on time, but we also did not reply to your emails or proactively update you on the progress. That was our mistake, and we have no excuse. You have already received a full refund. We are seriously improving our internal processes to make sure this does not happen again. We are truly sorry for all the frustration and anger we have caused you.

If I could give minus review I will. DO NOT BUY FROM THEM AND HERE IS WHY: I had requested cancellation on my order (turns out I don’t need it). Cancellation was requested same day I put an order. They ignored me and next day I got message that shipment was processed. I chased the BS with them and they are now trying to pretend that it’s beyond their means! HOW ABOUT HELL NO. Just because your CS sucks and you would clap your ears to make customer keep product but sorry that ain’t happening. If you keep rejecting my cancellation I am claiming fraud with my bank (because technically speaking IT IS FRAUD). I have screenshots of your own website and that your policy says: „You can cancel or change your order for free, but only if you contact Kosiner Jewelry before the item ships (usually within 24–48 hours of your order). Once your order has left the warehouse, it can no longer be modified or canceled.”

Dear Donna, Thank you for your feedback, and we sincerely apologize again for the frustration you experienced. We want to kindly remind you that we already processed your full refund on June 2. Depending on your bank's processing time, the refund should have already appeared in your account by now. Regarding the order – it was shipped out before we could process your cancellation request, as we had stated in our policy. However, since the refund has already been issued, please consider the delivered item (if it arrives) as a complimentary gesture from us to make up for the inconvenience. We truly regret that your experience was not smooth, and we appreciate your honesty in helping us improve. Best regards, Kosiner Jewelry Team
