How It All Started

When I look back at all the romance and joy my creations have brought to thousands of couples, I can’t believe it almost never happened…

From early childhood I would spend hours dreaming up magical ideas; sketching, painting, and sculpting the things that fascinated me.

It wasn’t until I was a teenager that I stumbled across an article in a magazine about jewellery design with amazing images of cutting edge designs, I don’t know how to explain it, but it was definitely a “light bulb” moment, and that’s when things changed.

I was so excited by the idea that I could imagine an object, design it, and then create something out of nothing. Just an idea, I was captivated.

The next step was to find an apprenticeship and I was surprised to get a job offer very quickly.

When I arrived for my first day at work, I was told there was no longer a job for me and when I asked “why?”, the answer I got hit me like a brick; I was told that because I was left handed I would never make a good jeweller and that I should look for another career. Apparently, all jewellery tools were made for right handers, all my dream’s crushed.

After a day or two of questioning my dreams, and more importantly, who could tell me what I was capable of, I became even more determined and went out looking for my apprenticeship, only to realise that all the jobs were taken for that year. That was set back number two.

This obstacle had no impact on my determination; I found a job as a storeman in a Jewellery Supply Company, saved all my earnings, built a jewellery work bench and purchased some tools to set up my own workshop at home in my bedroom.

After a year of researching and crafting rings totally by hand with a very modest and limited set of tools, I was ready to find my start in the jewellery world – whatever it took.

As it turns out, my early disappointment was the best thing that could have happened to me. I was the only young hopeful to arrive at an interview with a small but impressive portfolio of rings that I designed and handcrafted. This led me to being chosen as an apprentice in one of Sydney’s leading jewellery workshops, a moment that changed my life forever.

After four years of training, I finished my apprenticeship and was awarded apprentice of the year, my first wonderful career achievement.

Today I look back over my 43 year career as an award-winning jewellery designer and master craftsman and realise that I have the same passion and drive for the magical world of designing and creating pieces of enduring beauty that become a part of people’s lives, what a privilege.

Every jewellery piece that leaves our crafting studio has to be perfect and contain the love and passion that our clients have for each other, it’s that simple.

I am always excited to meet with new clients and create an amazing piece that is designed just for them, something that will be treasured for a lifetime.

Over the years, we have had the privilege of being able to create many different engagement rings, wedding rings, and other unique designs of jewellery. We have used a wide variety of different precious gemstones, including coloured diamonds, rubies, sapphires, and much more. You can see some of the feedback we have received from our customers over the years on our testimonials page, and we guarantee that we will work tirelessly to ensure that our customers are 100% satisfied.

I just wanted to say a big thank you for your excellent Customer service (Carl) and brilliant craftsmanship & advice (Edward)! I absolutely love my ring – the diamond, design and fit is everything I wanted!! I have so many comments every day and I tell them exactly where and who did it! I look forward to seeing you both in the next 8-10 months to get our wedding bands done.

Thank you for everything once again!

Hi Carl & Edward,

We are thrilled to let you know that Jarrod popped the question (and I said yes) during our holiday in Africa. I absolutely love the ring – it is stunning and even more beautiful than I anticipated. Thanks so much to both you and Edward for an amazing piece, one which I will treasure for a lifetime.

Many thanks

Hi Carl and Ed,

I just wanted to say a huge thank you to Ed and yourself for all your hard work and being able to complete the ring in time. The finish is amazing and I couldn’t have hoped for a better design and finished piece. Thank you for all your help and advice throughout the process, it made it easy, fun and put me at ease knowing your expertise and high standards you set for yourselves.

Tyrolin absolutely adores the ring as well as the little touches such as the saw piece and it fits perfectly!  She said she couldn’t have hoped for a better proposal and ring.

Many thanks, Alex

Jarrod Alati

Hi Carl,

Obviously it all went to plan. She loves it and the size was spot on.

Just wanted to say a big thank you to you and Edward for the exceptional service that you guys provided. Absolutely second to none.

Will be in for the wedding bands for sure.

SHE SAID YES…. And then gasped “it’s better than I could have chosen myself!” as she looked down at the ring.

I cannot thank this father and son team enough, they go above and beyond to serve you. So if you are wanting to make your special person feel extra special by going the extra mile then this personalised process will do just that and you will have brownie points in surplus for years to come! Thank you Carl and Edward for making this such a positive experience, Anita keeps smiling in awe of her  “beautiful new shiny object” every time she looks at her hand. We can’t wait to have you design our wedding rings for our next chapter!

Hello Carl,

I have been meaning to email you since I received my ring from David to tell you how much I love it.  Thank you to you and Edward.  Thank you also for your frank advice about what size the shoulder diamonds should be, they look wonderful at 0.75ct.  The setting is absolutely perfect too.  There is not a day that goes by without people commenting.

I love it so much, so thank you.
