I have received my snake 14kt gold earring and I'm pretty impressed. They definitely feel like they have been made with quality in mind. The team has also been fantastic to deal with when I've had questions about my order. 10/10 will order again! I will never have to deal with pointy earring backs again!

I purchased 6 ear piercings, five of them with flat backs, and one hoop. I’m very happy with my order. The flat-back style is extremely comfortable for everyday wear, and the quality of the jewelry is excellent. The stones are beautiful and very sparkly, and the pieces look like genuine, high-quality 14K gold. I did have an issue with 3 of the piercings because the post size wasn't quite right for me, but customer service was amazing. They were kind, responsive, and resolved my issue quickly and professionally. Shipping took about a week, which was reasonable, and so far, the jewelry has been very durable. Overall, I’m extremely satisfied with both the products and the customer service, and I would definitely purchase from them again.
