We were very happy with the experience at Sedgwick’s. Patti was very knowledgeable, worked to our budget and helped us through the process of selecting a diamond and choosing a design. We now have a beautiful engagement ring which we love. We would highly recommend Sedgwick’s and are going to use them to make our diamond set wedding band!

As a collector of Antique jewellery I am very fussy about the authenticity and condition of all items I purchase. Sedgwick’s guarantee both. They were happy to send me additional item images that I was interested in and answer my numerous questions. Patti is very knowledgeable about Antique Jewellery and has been able to track down some unusual items for me.

Over the years I have purchased beautiful jewellery from Patti including antique rings, a South Sea pearl bracelet and a pair of diamond earrings. These pieces are as beautiful as the day I bought them and have given me great pleasure. Patti has also arranged my insurance valuations and remodelled some of my old peices. I heartily recommend Sedgwicks.

Sedgwick’s was able to source for me an Omega Dynamic wristwatch that I had been looking at in London. I wear it regularly and always get compliments. They arranged to have it serviced and supplied a new strap when needed. Very happy with the experience.
Searching for a replacement engagement ring we were fortunate to find Sedgwicks Estate and Fine Jewellery. We couldn't fault the professional service we received. Patti thoroughly understood our brief, she was efficient and informative and spot on with estimations and values. A great experience, and a great result as we found the perfect replacement ring. Patti has the rare gift of professional expertise coupled with a down to earth practical approach to her business and a great sense of humour. Her integrity is second to none. My husband and I can't speak highly enough of Sedgwicks Estate and Fine Jewellery.

Fantastic personalised service from the very beginning with Patti. My fiancé couldn’t be happier with her ring. Patti’s knowledge in the industry and the honest feedback she supplied me with was inimitable. The expertise and time that I received throughout the entire design process was second to none. Patti is extremely attentive to detail and really went the extra mile to provide the perfect ring for me. I can not recommend her business enough.

Patti Thank you very much for my two lovely rings, and the valuation. And thank you for taking the time to tell me about the history of the pieces, and for explaining the process of the ceylonese stone. I don’t know much about minerals and their processes but I appreciated the information (please don’t test me later!). Gives more meaning to the piece and I particularly enjoy having a piece of Australian history. The wedder is a delight to wear. Best wishes with Sedgwicks, Patti, you deserve every success. Regards, a very happy customer.
