Sydney-Based, Family Owned & Operated

Founded in 1983, SJ Jewellers began in a small workshop beneath a family home, built on the kind of craftsmanship that can only be passed down through generations.

Today, that legacy continues from our private Sydney Studio, where clients work directly with the jewellers who design, source and create their pieces in-house.

Designed For Life's Most Important Moments

From the get go, James had a friendly approach and no change was too big or too small. Their knowledge, designs and workmanship are unmatched. The design process was a dream and so seamless and even created 3D designs for my partner so he could get a feel of how it would come together.

We cannot recommend Steven James enough for your jewellery needs as our wedding bands came out absolutely beautiful, they are everything we could’ve asked for!!

I had an amazing experience with Steven James Jewellers. I dealt with Jack, and he was incredible from start to finish. He helped me design and bring to life my fiancée’s engagement ring, and the result was perfect. His attention to detail, communication, and overall customer service were genuinely outstanding. Highly recommend asking for Jack if you want the process to be seamless and stress-free.
I would highly recommend Jack and the Steven James team to create your engagement ring because their work is like no other! All the work they do is all in house and their craftsmanship is just impeccable!

I am so happy with my engagement ring and cannot thank them enough for making my dreams come true!
Hazel Jameel
Great quality of service and product as well as knowledge, advice and communication.I wouldn't hesitate to reach out to them again in the future.

It can be pretty daunting for someone who doesn’t know much about jewellery to go and buy an engagement ring, but Jack’s honesty, knowledge and guidance made the process a breeze.

I couldn’t recommend Steven James enough! My fiancé and I are beyond happy with the result and will definitely be returning for our wedding bands and jewellery in the future.

Incredible experience with Steven James Jewellers. Was very nervous before attending. James explained the 4cs so clearly for me to understand with all the designs that were possible. He came up with the design and ring suiting my exact budget. My now fiancé has fallen in love with the ring and I can not be more grateful to James and the team for such an amazing experience and product. Much appreciated!
