Our experience with Sky Gem and in particular Aaron’s service, has been nothing short of exceptional! Aaron is incredibly accommodating, and ensures that every detail of the engagement ring is crafted to perfection. His professionalism, expertise, and genuine care makes the entire process seamless and enjoyable. Aaron took the time to understand exactly what we were looking for and ensured that the final result was not just beautiful, but absolutely perfect. The ring itself is an absolute masterpiece. The sparkle and brilliance of the diamond, the flawless setting, and the overall design exceeded all our expectations! I couldn’t be happier with my engagement ring! If you’re looking for exquisite craftsmanship, exceptional service, and a jeweler who truly cares, I highly recommend Sky Gem!! :)

Aaron was incredibly helpful from the start, provided more information than expected and was a pleasure to deal with. He assisted me with choosing the best size and shape and the final product was perfect. I couldn't suggest SkyGem & Co and Aaron in particular, more highly.

Really happy with the engagement ring that I purchased from SkyGem & Co ! Me and my partner did not really know what we were looking for and Aaron was really helpful in explaining the varieties and qualities of diamonds before we decided on one. We ended up ordering with a customised setting and really satisfied with the result !

Amazing customer service and were thoughtful and considered when suggesting options. They were quick to reply and even when I picked my diamond, they suggested more that were the same value but better quality!

Aaron and the team and sky gem & co have been absolutely phenomenal! We loved our entire experience from the engagement ring to picking out wedding bands. Aaron is a wealth of knowledge and we couldn’t have asked for better guidance when it comes to diamonds! Thankyou to the entire team, you have been such an amazing and integral part of our wedding journey! Couldn’t have asked for better!

Highly recommend Sky Gem and Aaron for your engagement ring needs! From the beginning, he was attentive, he took note of all the details that I was after and was able deliver flawlessly. Aaron provided excellent service, he showed professionalism and was easy to communicate with. I had a specific design in mind and he was able to make the necessary changes until we were all happy with it. The ability to fully customise the engagement ring sets him apart from other jewellers! Finally the process from start to finish was seamless as he was able to work efficiently to deliver the product! We were super happy with how it turned out and cannot recommend Sky Gem and Aaron highly enough!

Glad I came across SkyGem when looking for an engagement ring. Aaron very patiently listened to my needs from a design, quality and price perspective. He helped me through the process and made me feel like I was in good hands the whole time. I was quite specific with the design of the ring, which is admittedly nothing outrageous, but Aaron’s team executed the design perfectly. Further to this, the diamond selection process can be daunting for the untrained but Aaron listened to my wants re quality and size, we ended up with a beautiful diamond to crown the ring. Most importantly my partner is very happy. I couldn’t recommend SkyGem enough. Thanks Aaron, appreciate your help mate!

We had a great experience with Aaron at SkyGem. His price was competitive and my ring was custom designed to exactly what we wanted. Adjustment during the design was easily accommodated. Highly recommend, and I will go back again when wanting another personalised ring.
