Excellent service and value. The team including Leanne and Greg were there every step of the way during my journey (confusing at times), of buying an engagement ring. The ring was completed on time and is stunning. I would highly recommend CTJ to anyone looking for quality jewellery at a great price. Thanks again CTJ!
