I had a great experience with Kosiner…

I had a great experience with Kosiner Jewelry’s customer service. I bought an earring for my girlfriend but the post happened to be too small, they were understanding of my concerns and offered a replacement post at no additional cost, allowing me to keep my original earring! I appreciate their willingness to work with me to find a solution and make the process as easy as possible. Thank you for your help and for taking the time to address my concerns!

Great customer service

I ordered the wrong size and had reached out to the company in regards to an exchange. Straight away they were understanding and onto it and a solution was made in no time.

Not only is their customer service top tier and pro active, their jewellery is delicate and beautiful! Couldn’t be happier!

Will be repeat customers!

The jewelry shipped immediately and arrived timely. It is of high quality and as beautiful as in the photos.
Their customer service is responsive to questions and they stand behind their products. We will definitely be repeat customers!

I am deeply disappointed with Kosiner…

I am deeply disappointed with Kosiner Jewelry. I have reached out by email repeatedly over the past several months regarding my unpaid affiliate commissions, but the matter remains unresolved. The lack of meaningful communication and follow-through is unacceptable and raises serious concerns about how the company treats its affiliates.

I have invested considerable time and effort in promoting their products, yet I am still waiting for the commissions I earned. This experience has severely damaged my confidence in the company. I expect Kosiner Jewelry to address my requests seriously, provide a clear update, and fulfill its payment obligations without further delay. Based on this experience, I would be reluctant to recommend their affiliate program to others.

Is this a scam site??

Is this a scam site??
I have tried to make an order severel times cause ai love the earrings they offer, but my bank blocks my payment cause they are marked as unsafe.
I then tried in my boyfriends phone to make a klarna payment cause I thought is must be a mistake, but before I even went to the payment it blocked the side as unsafe and said it was trying to get the card payment info.
So it seems like a scam company.
Or I can’t buy from Denmark.

Dear Vanessa,

I completely understand your frustration, but please rest assured that Kosiner Jewelry is a safe and legitimate store. We are absolutely not a scam.

The block you experienced is a very common automated fraud filter issue with Danish banks and Klarna for international merchants. It is a false alarm from their system.

To help you complete your order, please contact our customer service directly at service@kosinerjewelry.com.

Please include a screenshot of the error message you received. Our team will quickly provide a safe alternative payment method (such as PayPal) so you can get the earrings you love.

We look forward to hearing from you at service@kosinerjewelry.com!

Best regards,
Kosiner Jewelry Team

I will never recommend this company

I will never recommend this company. They have deceitful practices. They are unwilling to accept returns and are rude when the buyer persists. The images they provide online do not match their products. If I can warn people about their scheming business practices then that will be the best outcome I can expect from having dealt with them myself.
I have had multiple terrible experiences with this brand. The only reason I have continued using them is that the number of internally threaded 14K flat back earring sellers is limited. My most recent purchase unfortunately has been the worst. The items I ordered arrived and as usual were significantly smaller than they appeared on the website but that is par for the course with Kosiner. The second and more important issue is that the gemstones in the earrings were clear when they were meant to be dark yellow citrine. I contacted Kosiner to ask if perhaps they had sent me diamonds instead of citrine because the image on their website was nothing like what I had received. They informed me that they had sent me citrine earrings but sometimes their citrine was very pale. I requested a refund and a return label. That is when Kosiner became truly nasty. They stalled giving me a refund for 5 emails. They offered exchanges, they were rude and they tried to claim that their return policy was different than stated on their website. Also once finally agreed to the return they informed me that they don’t provide return labels I would need to purchase my own label and I would not receive reimbursement for the cost. In addition the return address that they provide is not compatible with any shipping service available in the U.S. this is because they provide the company name for the return address but also a first name consisting of a name, number and symbols but no last name. Every shipper only allows letters and numbers for a first name but shippers also require first names be coupled with last names. l’m busy and by then the company had done as they clearly intended and run down my will to engage with them anymore. I accepted a 15% return for not having to return the earrings and ate most of Kosiner’s outrageous cost for their earrings.

Not only is the design lovely, elegant and subtle, but living by the sea, I can also attest to how well-made these earrings are and how beautifully they withstand exposure to water and the ocean.

Fast shipping and excellent customer service. I highly recommend KOSINER!
