Let customers speak for us
Could not be more happy with the engagement ring and personal service. The stone is absolutely brilliant. My fiancé cannot stop looking at it and has received many complements on the rings sparkle.
Simply the most beautiful diamond available. My wife gets nothing but compliments. Jim & Jean at Martoni & James are simply the best! I wouldn't go anywhere else!
Jim is an expert and educated me on exactly why the Sirius Star is so magical!
I suggest Martini & James be your Jeweler! Jim can help you design the perfect piece !
My original engagement ring was a 3 stone GVS1 and I loved it, however once I saw the Sirius diamond in person, it blew my mind! Light reflected from every angle and it was so much brighter than my original ring. I loved the Sirius diamond so much, I bought two...one to pass-on to each of my kids when my time is up. It's an investment you won't regret!
My husband and I purchased the Sirius Star diamond together when we were getting engaged and it was the best decision we made. IMO I have brightest diamond compared to my circle of friends. Needless to say, I am proud of this piece of jewelry and I HIGHLY recommend it for anyone looking for a new engagement ring. You will not be disappointed!
Got to work with Sirius Ice to make a hand crafted beautiful engagement ring. Absolutely stunning diamond in a classically unique setting. Their work is the highest quality. We could not be happier with the final product! We’ve gone back several times since for other pieces. Always fun to work with their company!
