The website for this company is clear, elegantly designed and easy to navigate. I purchased an opal flat back stud and it arrived quickly in lovely packaging. I had made a mistake in my order, so reached out to the customer service explaining. The responses were quick, understanding and very helpful, and the solution they suggested was far better than I had expected. I would definitely recommend this company and will purchase from them again!

I bought a cartilage earring for my sisters 30th birthday but the size I ordered was too small so I asked for an exchange. My email was answered very quickly and the correct size was organised within days. The jewellery is beautiful, perfect and exactly what my sister wanted. Customer service was great and I’m very happy with my order. Thanks to Nicole for organising the shipment.

I've bought a piercing for my girlfriend as a gift, but I've got it too small. The customer service was amazing sorting the exchange for me. When we've opened the box the packaging felt premium, good quality.

I ordered 14K solid gold minimalist flat back studs in white gold. 4mm and 3mm sets for my lobe piercings. Earrings are pretty and petite which I love. Looking forward to seeing how well the hold up since I don’t swap out earrings often. I reached out to customer service with questions and they were quick to respond.
