This company is the best I’ve ever brought from & dealt with. In simplest terms, I had an issue with one of the earrings that I previously brought. It was too small for my ears & I wasn’t happy with it. I emailed customer services support & told them about my issue. Instead of being combative and having a problem with this, they instead were the LOVLIEST people ever. They told me that I could choose a different set of earrings & they took off the price difference, which was such a nice touch. They also paid for shipping as I’m in the UK and made sure that I was completely comfortable and satisfied with my purchase. If you need to buy any earrings for either yourself or a loved one. This is the place to go, highly recommended it.

I received a post that was way too long with an earring and after a couple conversations via email, causing her has agreed to send me a smaller post. I appreciate their customer service and their promptness. The earring is also pretty.

It took me a while to place my first order. But I am glad I went for it. I think the pieces are great value for money. I got in total 9 pieces, 6 of them are earrings and the rest piercings. The diamonds have a great cut, clarity and color. I am super happy with my order and would warmly recommend!

I have just ordered my first helix flat back stud from them and I was really impressed with the quality of the item. I would happily buy from them again. I’m also based in Australia and the shipping was fast.
