Fantastic experience and service from our designer Janaya. My wife loves the ring and we were super impressed and grateful that the ring arrived before our 40th anniversary when we were expecting it to arrive about 5 days later - which we understood. However it was a fantastic surprise that we got it early. Thank you again xx
