From my first conversation with Carl, I was very impressed with his professionalism and expertise. I was searching for a very special gem to be made into a pendant in memory of my dear mother. I was quite specific with the type of gem and shape. I did think I was asking a lot of Carl to locate exactly what I was looking for. However, Carl did not give up, and he was able to locate exactly what I had hoped for. The gem was perfect!nAfter talking with Carl and Edward about the design of the pendant, Edward created several beautiful design concepts to complement the gem. Both Edward and Carl took the time to explain how the beauty of the gem can best be highlighted and a final decision was made. I knew and trusted something very special would be created by Edward. I was not disappointed. The final product was stunning and perfect. Just what I had envisioned.nThis entire process was undertaken via the phone and email, as I live interstate. I was initially concerned about starting this process and not being able to meet in person, but Carl made regular phone calls to keep me informed and sent photos throughout, so it wasnu2019t a problem.nI hope to one day meet Carl and Edward in person to thank them for creating a very special and precious pendant. Their expertise, professionalism and attention to detail throughout the process were of the highest standards. They are masters at what they do and together they have created a family business built on showing genuine customer care and achieving perfection.nI highly recommend and trust Carl and Edward to advise, source and create a very special, bespoke piece of beautiful jewellery for you.nThank you, Carl and Edward, for my treasured pendant, and the amazing journey we have shared together.

Working with Carl and Edward was extremely positive u2014 the whole experience from start to finish exceeded my expectations.nnCarl was very thorough in educating me on all the available options, taking the time to explain every detail and help me make an informed decision. Over a few meetings, we narrowed down the search until we found the perfect stone, then aligned on every detail of the ring design with Edward.nnIu2019m grateful for how calm and comfortable they made what could have been a daunting process. Being so involved in the process has made the ring feel even more special, and the end product speaks for itself.nnMy fiancu00e9e and I were over the moon and we canu2019t thank Carl and Edward enough for all of their help!
