I bought a 14k white gold piercing 2 month ago and I‘m wearing it ever since! Shipping and delivery was fast! Packaging so nicely done and the piercing itself is so beautiful and sparkly! Will definitely order more👍🏻

I have purchased from both their 14k gold and ‘regular’ collection. Both extremely pretty. The regular item (a necklace) looks good but does not seem to be of extremely good quality- however, as I only paid about £15 I do not expect it to last decades. It is a very pretty, lovely accessory. However, the 14k gold range was a pleasant surprise- it is real gold and is very well made. I got a stud earring with lab diamond and love it. Definitely a real deal, I have compared it to my diamond ring. I will definitely purchase from them in the future.

KS24759 Jewelry has fallen out of earring and havent had them long. Customer service was very slow, id emailed, messaged on chat from website and instagram. I even posted a comment on their post and they deleted it. 10.10.25 I have now had a response and issue resolved.

An earring arrived broken (1 of a set of 3). Have only offered a 50% refund as only one earring is damaged. On saying this was unacceptable as wanted the full set, they no longer reply to emails!

Still awaiting a refund for the product I received which is essentially a defected broken earring. No communication from the company. Stay away !!! Don’t waste your money !!!!

This is a horrible company , a 100% scammer! You pay with no item and someone will signed for you that you receive the order.

Thank you for alerting us. This is a serious matter. For your security, we strongly recommend that you immediately contact your bank to report the unauthorized transaction and inquire about chargeback procedures. They are best positioned to secure your account and assist with the refund process.

I've purchased from them four times now, all 14K solid-gold jewelry. I am very sensitive to any metal other than gold and titanium, so I know what I got from them is the real deal. Absolutely love their designs and quality, and found paying for express shipping worth it.

The worst seller ever – zero communication. The earring was extremely poor quality. I do NOT recommend buying from them. I returned the product in perfect condition, but now the only update I’ve received is: “Shipment held by customs awaiting information from the recipient.” No help, no response. Avoid this seller.
