It was my first time buying a diamond rings and the COVID lockdown meant shop visits were next to impossible. I found GC Manufacuring online and after going through their website I was immediately comforted that I had found a legitimate and professional manufacturer. The online order process was effortless and the various order confirmation details put me at further ease. I was notified when my order was completed and it was safely delivered to my house. I love the delivered product so much so that I ordered a second ring and personally went to pick it up.I wanted to shake Mr Costa's hand for creating a beautiful gift for my wife but ... COVID19 restrictions meant I could only elbow bump a one of a kind artist. The lifetime warranty is an amazing added bonus. I am grateful for a lifetime. Thabiso Mohare

Karind Ori
Mr Costa delivers a personal experience for you like none other. The craftmanship and attention to detail is world class. The diamond and platinum used on my fiance's ring was worth 2x the price I paid easily. I highly recommend Mr Costa. Grazie GC Manufacturing. Servizio eccellente!

Wayne Wilkinson
The stars for rating GC Manufacturing Jewelry is not enough as this company and Mr Costa is exceptional beyond words. Drove from Kimberley to Johannesburg. What an experience it was. I immediately felt welcomed and the advice I received was brilliant. Mr Costa definitely knows his industry and his market. The end product I received blew my mind away. I am definitely returning again. I highly recommend GC Manufacturing. Thank you very much to Mr Costa and his secretary. Bravo

Jacob Kretzmer
I am very happy to have chosen GC Manufacturing for the purchase of the ring with which I will ask for my girlfriend's hand. Not only an act of great responsibility but also an economic cost that should not be underestimated on these days. I therefore requested a lot of quotes before choosing GC and after talking with Gaetano I realized that I would have made the best choice. Thanks for everything, and I hope it's a YES .....! so I will be able to return for the wedding rings 😀

Excellent Service. Princess cut diamond set in Platinum. Absolutely perfect !
Alan de Freitas
I bought an online ring from Cape Town, quite skeptical at first but I must say that I was really overwhelmed, not only by the service but by the quality that compared to the price i paid. In a country where anything costs a fortune, it is rare to find an honest company like this. I thank Gaetano Costa for all his great work.PS: The same identical ring with the same identical material and type of diamond in a store (chain stores in South Africa) cost 3 times more and already discounted.
Ricardo Andrade
Was very well received at GC for my consultation. Mr Costa knew exactly what I wanted and delivered beyond my expectations. He was very helpful, and always available to discuss anything and also very willing to incorporate any design ideas and details at any moment. Also gave me many great ideas and suggestions. I was really amazed by the final product!
Paul Du Plessis
I could not have made a better choice. Gaetano guided me to make the best choice for my ring. Since I entered his office and talked to him, I knew he was the right person to make my ring. Very professional and extremely competent in his work. Thank you so much for your service.

Gaetano worked miracles on my wedding ring. I went to him to have my ring remodeled, he was so friendly and helpful, he made some good recommendations and his prices are very reasonable. A week later he called me to tell me that my ring is ready. When I saw the ring I could not believe that it’s the same ring. He had even added a few more diamonds without changing his initial price because he does not compromise on quality. You are so gifted Gaetano and I’m so happy I brought my ring to you. Thank you so much and God bless you.

I had a ring that was in real bad shape. Didn't know what to do. Found them on facebook. I've send them a message on the page, from there on it was satisfaction on satisfaction. They gave me good advise and the outcome amazing. They fixed my ring at minimal cost. I've posted the ring on a Thursday and the week after on the Tuesday my fiancee was wearing the ring again with the date inside the ring when we got engaged. I am in the Northern Cape and this was an emergency. They know what they are doing Real fast and really good customer satisfaction. Great communication. Fast and reliable. Definitely recommended and I will definitely go back. Thank you very much for being so helpful.
Victor Windson
Great, really great service provided by Gaetano and his team. I order the ring from London UK, and everything went 100% well, from ordering to the delivery. I recommend this company to everyone for prices and excellent service. Thanks again:)

I can't rate Gaetano's work high enough! He was professional and accommodating in my fussiness and requests. He redesigned my wedding ring completely and added a stack ring in 10 days. The workmanship is outstanding, price is amazing and Im beyond thrilled with my new set!

Even resizing wasn't a hassle at all! THANK YOU :) We will be back for more :)
Kelz Benz
Where do I start rating such a GREAT customer centric company with the BEST guy ever being Gaetano. Gosh I started chatting to Gaetano via email because I live out of South Africa and made an appointment to see him on a Sunday (he opened especially for me). I came along with an image of what I wanted and he assured me he will make me a beautiful ring.
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
Marco Razzino
The greatest and friendly service. Fantastic design. Thank you
Stephy Bronkhorst

Callum Murray
I found GC Manufacturing by chance and what a find. I needed a special design for an engagement ring and upon visiting Gaetano Costa at his office no effort or request was too much and he assisted me professionally in obtaining and achieving exactly what I wanted. Gaetano talked me through the whole process, including time lines, costs, delivery to Cape Town etc. etc. From the moment I visited GC Manufacturing Jewellery in JHB to the time when the ring was delivered by courier to Cape Town the professionalism and communication shown by Gaetano Costa was excellent and I will highly recommend them for all your jewelry needs.
Katlego Olifant
Thy r so beautiful
Vicky Wale
Fantastic, I would recommend gettting your ring made here to anyone. I had the Bianca band made for my wedding ring and was slightly nervous at first as even though the website is very easy to use etc it's nervewracking when you purchase a ring you haven't actually seen or tried on. I had nothing to be worried about, the communication throughout the whole process was brilliant, the ring is stunning and Gaetano talked me through diamond certificates etc. I will definitely get more jewellery made here.
Fatima Saley
Gaetano was extremely efficient and provided me with the best service. I required a valuation certificate for my fiancée's ring for insurance purposes and found G.C Manufacturing Jewellery that offers this service. I made the payment and within 10 minutes Gaetano sent me the valuation certificate. He is absolutely brilliant and I recommend all of you to visit him at Benmore gardens shopping centre in Sandton, unit LG29. You will not be disappointed, his customer service is brilliant. I don't use social media, but I was so amazed with his service I used my mum's account just to write this review. Thank you for your amazing service Gaetano. You are the best. Keep up the great work G ! - Azhar Saley
Jerome Sweetland

Gaetano firstly did a valuation on a diamond ring I inherited and then made my wedding ring using the diamond. He always provided prompt feedback and the turn around times far exceeded my expectations. The ring he made looks amazing and is exactly what I asked for. GC Manufacturing is conveniently situated in the Benmore area. I will recommend his services to anyone!

I was referred Gaetano Costa Manufacturing Jewellery by a good friend of mine. I was told that they would see to my every need and assist me in the manufacturing of an engagement ring for my now, fiance. It gives me great pleasure to now write this review, If it were possible, i would without a doubt rate them 6 stars! Upon my arrival there i was greeted by a friendly and professional young man called Gaetano. Gaetano assisted me in informing me all about the process of manufacture as well as guided me through choosing the right design for the ring. I entrusted them with my requirements and off i went. In just a few days my ring was ready for collection. An almost effortless process. I proposed to my lady and made her my Fiance. She was extremely happy with the engagement ring and so was I.
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.
