Amazing customer service pre-purchases but also post-purchases. Gaetano is highly experienced. He is a fabulous jeweller that has a heart of gold. He is always willing to go out of his way to assist customers whereas to advice them...
Few people are still as passionate about their work and it shows in the product! My ring is passionately gorgeous!
My ring is back on my finger and I can not be happier!
Fast and friendly service.
Fantastic design and workmanship, friendly service. A true value added experience !
THANK YOU MR COSTA
We already had a picture about what we want .explained and discribed what we’re looking for.
A few weeks later we received our wedding bands what was much nicer than expected.
A big thanks to Gaetano and the team for a perfect work.

Just collected the ring that Gaetano has made me for my 50th birthday and it is spectacular! Superb workmanship. Thanks so much, it's wonderful to work with you again.
The website is also great extremely well done.

I will definitely be recommending you to friends and family!
I must say, I had doubts going into this as it was the first time purchasing something of such value over the internet. Gaetano definitely set our minds at ease and delivered above and beyond!
Thank you so much! We will treasure these forever! We will be in touch in a few years for an anniversary gift :).
Picture loading......will share after my wedding :-)
Thanks G.C Manufacturing Jewellery and continue making your customers shine like DIAMONDS
Even resizing wasn't a hassle at all! THANK YOU :) We will be back for more :)
Being a girl I wanted the Biggest Rock but as a professional jeweler, he advised that my fingers were small and that I should keep to a certain size for my center stone. Boy am I Glad I went with his suggestion.
I went back home and sent an International Transfer deposit and my ring went into production, I requested step by step pictures of the ring making process and he gave me that (I am big on memories). when I got the completed ring picture I was loving it, however nothing could prepare me for seeing the ring LIVE when we went to collect the rings.
I say TRUST him to make you a memorable piece of jewellery especially engagement rings, wedding bands.
P.S he made my future hubbys wedding band and it got some special message engraved from me to him (again a thoughtful suggestion by Gaetano)
I could go on and on BUT I AM OVER THE MOON...don't hesitate to use their services. It is professional plus they will clean and polish your ring once a YEAR on the house...what an after sales PROMISE
But when i received the ring it went way past my expectation.
The most beautiful work i have seen.
My new favorite jeweler.
Highly recommend we will be shopping there again and were very happy with past purchases.
Well done , keep on doing what u do best.
My wife was extremely happy!
If only everyone could run their business as professionally as this, there would be many more happy customers out there. I will, without a doubt be using Gaetano Costa Manufacturing Jewellery again in the future and urge all my friends to give them an opportunity to handle their jewellery manufacturing needs. Thank you guys for making it possible to make my lady the happiest lady in the world.
Done over 5 rings with Costa, and every time was 100%
thank you very much.
