Had a custom ring made for my mom and Jim was a pleasure to work with! The ring turned out better then I could have imagined and the process was a breeze! Will definitely be coming back!

When I wanted to build a very unique pendant for my wife for our 10-year anniversary I contacted Jim. We had a private meeting in his office and in a matter of minutes he turned my drawing into a plan. He & Chris were both excellent at each step from concept, to mould creation, & to through to completion. I'm incredibly happy with their service and we both loved the piece. Thanks guys!

Went by his the extreme positive Google rating and couldn’t have chosen a better place to make my fiancée’s engagement ring. Mr Omori is extremely knowledgeable and I trusted him fully during the process. The ring came out beautiful and everyone loved it. Extremely recommended.

It was a great idea choosing them to make our engagement rings. They listened to our design plans carefully. Jim is pretty professional and gave us detailed suggestions. He also communicated us so much closely. We felt family atmosphere when we discussed in the office. He listened to me something in my private life and gave me beneficial advices. I really respect their amazing work and recommend others this place to make rings.

My Fiancé surprised me with the most beautiful ring he had designed with Omori. I am still in absolute shock with how stunning and perfect this ring is. I have tried on rings before at many jewelry stores and I can honestly say none of them can compare to this. You can tell the time and detail that goes into their work, this quality simply can’t be beat. Thank you so much for working with my Fiancé and making this ring so special. I absolutely love it ❤️

I recently purchased an engagement ring from Omori Diamonds. As someone with a limited amount of knowledge about jewelery, I can solidly say that they made this experience smooth, easy, and successful. The owners treat you like family quite literally. They took time to get to know me personally and put together a showcase of rings to show us based on our likes and dislikes. When we couldn't quite one with everything we were looking for, they helped us customize a ring that perfectly fit all our wants and fit our price range perfectly. The owner was constantly in touch with updates and involved

Jim was incredible to work with! He brought our design to life. The customer service from Jim and his son is outstanding! An experience you will not get at a chain retail jewelry store! When we picked up the ring all I could say is wow! It was beyond my expectations! We thank you so much!

If you don’t want to read the long review below, all you need to know is Omori provided the best service I’ve ever had, and the engagement ring is perfect.
Words cannot describe how great my experience at Omori was. After visiting several custom jewellers in the city, I decided to work with Chris and Jim as I thought they would help my vision of a… perfect engagement ring come to fruition… and I was right. They spent an incredible amount of time finding me the PERFECT diamond within my price range. After going above and beyond to get the perfect diamond, they exceeded

I was looking to surprise my girlfriend with a custom engagement ring, and Omori was recommended by several people. After seeing all the positive reviews here I knew it was worth a visit - and we sure are pleased with the outcome!
I knew the perfect ring would be non traditional, gemstones instead of diamonds, have colour and a connection to nature.
Jim clearly has been in the business a long time and asks the right questions, is patient, and genuinely wants the final product to be perfect.
I was very new to the custom design process & jewelry shopping in general, but Jim made me feel comfortable

Got a black diamond stud earring for my bf’s 30th birthday from Omori Diamonds. My bf loves it and wears it everyday. Thanks Omori for helping me be able to get the best gift for him.
Jim and his son were both welcoming. They are very knowledgeable and helpful. I do recommend them as they both make beautiful engagement rings.

They are amazing! My fiancé secretly found them and he had only the best things to say about Jim. Omori did the most beautiful and unique engagement ring for us. They are extremely attentive and their craftsmanship skills are fantastic. I wanted a vintage ring from the 30's, quite deitailed, and they did it! 😍 Thank You Omori Diamonds 💎 I'm never taking this ring off!
