Andrew Buck
With little notice and a short timeline given, Georgia and the team at Larsen came through with the most beautiful ring. She said yes!!I would highly recommend.
Steven Johnson
Absolutely incredible craftmanship and service! I worked with Fleur from the Larsen team to create a custom-designed engagement ring. Both myself and my fiance were incredibly pleased with how it came out! Fleur sent across computer images of the ring design based on our consultation and the final product was exactly as pictured. Not only that, but Fleur worked with me to get international insurance on the ring and helped me to save on GST by getting all of the papers for the Tourist Refund Scheme (as I'm an American and was working in AUS). Would highly recommend Fleur and the Larsen team - the quality and service cannot be matched!
Kurtis Parle
