Both Iris and Agnes have been really great and helpful from the start till the end of our ring hunting journey. Recommended to all budding couples who are looking to settle on a ring soon! Will add the photo of the ring once the proposal is done!

Can’t thank Iris and Sharon enough for my lovely ring. We had a great experience right from our first meeting in their tastefully done studio, where Iris took us through all the details, with a lot of patience. Not once did we feel pressured, which added to the trust. They were also very supportive in helping accommodate our tight timeline. My first ever solitaire and I couldn’t have asked for anything better! Thanks for making our 10th anniversary so special 💕

A big thank you to Sharon, Agnes and the entire team behind Authica for helping to craft the perfect ring for my fiancee! I was blown away by the team's professionalism and attention to detail throughout the entire process, from the initial consultation, all the way to the final collection of the ring. They were also very accommodating as they helped to rush the production of my ring within a very short amount of time, while still maintaining a high level of attention to detail! Once again, thank you to the team and I'd highly recommend Authica to anyone looking to create their perfect ring!

I’ve been engaged for a few months and I have to say that I’m still in love with my engagement ring. My fiancé and I went ring shopping to understand my preference/liking better. Sharon and Iris were very welcoming, informative and patient throughout the process. My fiancé decided to go with them because I only wanted lab-grown diamonds. On the other hand, I wanted to surprise my fiancé with an engagement band too so I explored some options with Sharon and Iris. After a few conversations, we settled on a sleek hammered ring (which I really like!). We are happy that both our rings are from Authica J. P.S This is long overdue but I still want to thank you both for making our engagement ring experience a delightful one!

Went to multiple Jewellery shops for Engagement Ring, ultimately chose AJ because of their ulticut quality, detailed presentations, explanations and live display. There was also close follow up on the ring collection. Thanks to Iris, Sharon and the AJ Team.

Had a very pleasant experience with Authica J. Firstly, they provide a good range of ring design and are very patient to provide their experienced advice. Secondly, they go out of the way to help customers. Iris and team helped me to get my proposal ring as soon as possible. Thirdly, they ensure the quality of their products. They perform rigorous checks to ensure that their diamond is of good quality! Definitely worth the price. Thanks Team Authica!
