“This was one of my best experiences purchasing fine jewelry online. I bought a beautiful 14k gold herringbone necklace from this shop. The seller was wonderful, promptly answering my questions. She also sent me some additional pictures that I requested, including a photo of the necklace worn, which if you buy jewelry a lot you know is a must! Shipping was extremely fast and I was opening my well packaged and polished necklace the next day, despite being an international customer. I will definitely be keeping an eye on their stock and look forward to shopping with them again soon.”
