Let customers speak for us
We are repeat customers of James & Irisa’s after having purchased a custom engagement ring in 2021. Having been thrilled with their craftsmanship and exceptional customer service, it was imperative to us to be return customers when it came time to order a wedding band. Another seamless process and James & Irisa have again gone above & beyond to provide a positive experience to us. Their resizing process was also second to none. Thanks again!
The wedding band suits my engagement ring beautifully!!
Absolutely beautiful and unique i cant wait for the other one i ordered
From start to finish, James and Irisa were unbelievable. Irisa looked after me and guided me throughout the whole process and putting up with my constant emails and questions. The ring came out better than I could’ve imagined! I’m sure that was the true reason she said yes.
Thank you James and Irisa for everything.
I am beyond words upon receiving my beautiful black opal ring. It is exactly how I envisaged and what the photos/videos Irisa sent me. Absolutely stunning! Their designs are so unique and that was the main reason why I went ahead with them.
Irisa has been such a pleasure to deal with. Efficient and professional. The whole process was such a great experience thanks to her.
I can’t recommend them highly enough. Thank you James and Irisa, for creating a piece of “superpower” for me.
I’m completely in love with my emerald eternity ring. The French fishtail setting adds such an elegant, vintage touch—it’s delicate yet secure, and the way it lets the light in around each emerald is just stunning. The stones are beautifully vibrant, and the craftsmanship is flawless. It’s everything I hoped for and more. Thank you for bringing this dream piece to life.
I just wanted to say thank you so much for the gorgeous ring! I have attached a photo of it, she was so happy with it.
Absolutely gorgeous! I purchased as a new everyday wedding band for an active lifestyle so my wedding set (also from James and Irisa) doesn't knock on everything. The band is lovely and makes a statement without being huge. Great quality as always too.
James and Irisa were amazing every step of the way when designing and making my fiancés engagement ring. We ended up making significant changes to the original design and they were very accomodating. The ring is gorgeous and very well made. My partner and I love it and wouldn't change a thing. Highly recommend!
We just received Tom's wedding band, it's absolutely perfect!
I love the way you added the larger peaks, and it fits just right too.
Thank you again for being part of our engagement/soon to be wedding.
It means a lot to us that we both have such unique and sentimental rings from the same place. Your service has been exceptional!
I couldn't be happier with the stone and the diamonds and the setting and the whole darn thing.
I couldn't have dreamed of a more perfect engagement ring. The yellow diamond is absolutely radiant—so full of warmth and sparkle—and the unique cluster design makes it feel like a one-of-a-kind treasure. The craftsmanship is exquisite, and it feels incredibly meaningful to wear something so thoughtfully made. I still catch myself staring at it in the sunlight. Thank you for making this moment even more magical.
I hope this find you well I just want to say a massive thank you for producing such a beautiful ring for my beautiful now fiancé, you guys made this a very easy and stress free experience I will most definitely be recommending you to all my friends and will be making purchases from you again
