Janet assisted me recently in designing and creating a gift for my wife. I found her knowledge and customer care skills to be exemplary. Upon handover the finished product was stunning, I could not have been happier. Thank you very much Janet.

I have to say the service and professional advice I received from Jermaine last weekend was 2nd to none. If I had any thoughts of buying the engagement ring from any other store but CTJ vanished after meeting Jermaine. He spent hrs with us finding out exactly what we wanted and designing our ring. He was professional and and has a complete understanding of all aspects of jewellery and design We didn't feel rushed or pressured at any time. If your in the market for any type of jewellery I couldn't recommend Jermaine at CTJ any more highly. This degree of service and salesmanship is a lost art and very rare .

Can’t speak highly enough of Greg, and the team at CTJ. Was great to deal with throughout the whole buying experience. Took his time and was happy to answer all of the questions that I had, regardless of how minor they were. Provided plenty of options, and at no point put any pressure on me to purchase, but gave me plenty of time to think through. Made up a spectacular piece when I had decided, and was prompt with completion and sending it on. Would highly recommend to anyone - can’t thank Greg and the team enough!

I have had 2 pieces of custom jewellery built by Greg and the team for the missus and both are absolutely beautiful. The workmanship is flawless and perfect in every way. For any custom jewellery please go and see them as the work they do is impeccable.

Greg and the team really looked after us! Better price, better diamond clarity, cut and colour compared to bigger retail stores. I had super quick turnaround with getting the ring and it blows my mind every tie when I see it in person. My fiancé is obsessed with it! Thank you so so much and I will be referring all my friends!

We worked with Janet to create a custom his and hers ring set with a rather soft stone. We cannot recommend her and CTJ enough. Firstly, we’d received a quote from another jeweller for a 9k gold setting, whereas Janet was able to quote us a much better price for 18k! She was super helpful, helping us to refine the little details that ultimately made our rings better than we had originally planned! Thanks so much for your professionalism, speedy turnaround and for not ripping us off unlike other jewellers! 10/10, we love our rings!

CTJ were amazing as they guided me to pick an engagement ring. They were patient as I was very indecisive of what shape stone I wanted. They were transparent and not pushy! I just got my ring and it’s gorgeous. Everything is just what I asked for. Thank you Greg and Dianne.
