Original poor customer service has vastly improved.
Update January 2026: I would like to update my review again. It would appear the company have upped their game and improved their customer service. I would like to mention they sent me my original order that I placed free of charge as well as a full refund. I am happy with how they resolved my problem
Update dec 2025: the company have contacted me twice asking me to update or remove this review. I finally received a refund almost two months after my original purchase with a simple screenshot of a refund. I thank the company for finally giving it to me but I still stand by how it should not have taken so long and me being ignored by them in multiple platforms. It's like the tables of have turned now they are trying to chase me. Although it appears they may possible have improved their service now, I will not purchase from this company again.
Very bad. So not buy from here. Ordered on June 9th . Was due for delivery June 20th. Still not turned up. Was told I need to wait 30 days for a refund for my parcel to be deemed as lost. Been over 30 days and they said they would refund me 5 days ago on 2 days time. No refund and no response to any emails.

Cheap goods from China
Cheap goods from China, a total rip-off, and absolutely terrible service. Save your money and don't shop here! NO STAR AT ALL.

Dear Ms. Melisa,
Thank you for taking the time to share your shopping experience. We truly value your feedback and sincerely apologize that the product did not fully meet your expectations.
We would like to take this opportunity to clarify that moss agate is a 100% natural gemstone, not man-made glass. As a creation of nature, each piece of moss agate is completely unique—its “moss-like” patterns, color intensity, and distribution naturally vary from stone to stone. This individuality is part of the natural beauty of the gemstone, which means it cannot be as uniform in color or pattern as a standardized, manufactured product.
We understand your expectations regarding color, and we acknowledge that natural gemstones can sometimes differ slightly from one another. We always strive to represent our products as accurately as possible. All product photos are taken from real items; however, differences in lighting and screen displays may also cause subtle visual variations.
We have already reached out to you via email at service@kosinerjewelry.com
and would be happy to further discuss the situation and offer a satisfactory solution, such as an exchange or a refund. Your satisfaction is very important to us, and we sincerely hope to have the opportunity to make this right for you.
Thank you again for your understanding and valuable feedback.
Thank you,
Kosiner Jewelry Customer Support Team

Great quality for the price
It took some time for the international package to arrive but they processed it super fast. Also, I do get the best quality for the bucks. They always have some kind of promotion going on. If not on their website, then their social media's got a code somewhere. That's how I got my 14k solid gold studs at a discount at least 😂

I have purchased from this company…
I have purchased from this company twice now and I just discovered it a month ago. I have worn my earring stack everyday for the past month and it has not tarnished at all! No irritation or itching ever either! The earrings are very secure for the most part, but I had a pair fall out and I worked with a very helpful and nice employee who bared with me for a couple days and is now sending me a pair of earrings for free! This is my favorite jewelry brand by far and I get compliments on my stack everyday and I recommend their brand to all of my friends and anyone who asks. :)

Order at your own risk x
Asked for them to cancel my order before it was shipped, no reply on their emails, WhatsApp or live chat for days, they reply back to me AFTER it’s been shipped out and it’s too late to cancel… I asked if I can return it and they recommended to give it to friends/ family! I need a refund not give it away! Very bad company, don’t buy
Edit: almost a year later they have refunded me
Edit again: they have given me a $20 gift card as an apology. Now this is what good customer service is! ❤️

I regret about this purchase
I regret about this purchase. I payed for some jeweleries and they send my the half of them. And the worst of all is that they don't answer to my emails. Be careful.

Hi Άννα Ευθυμίου,
Thank you for reaching out. We appreciate your feedback. Our website lists this item as a single earring, which we understand can be confusing, and the reason why you received thehalf of them. We are updating the product description to make this clearer. If you are not satisfied, we can quickly process a full refund for you.
