Excellent service, truly unique prices. Thanks Gaetano for all the good work done. I'll be back for sure for some more jewellery. I strongly recommend GC Manufacturing.
Bill Cheney
I tried the same day repair service, excellent, very fast and convenient. Thanks GC Manufacturing Jewellery.
Stephan Van der Merwe
I am South African but reside in Australia. I wanted to buy the engagement ring in South Africa for a more sentimental value. I searched and found GC Manufacturing and chatted directly with the owner Gaetano Costa. I requested a replica of a ring that belonged to my mother (was stolen in South Africa), I sent old photos of the ring to Gaetano to see if he could have done the same type of design. Obviously my expectations were not to have the same ring but something quite similar. I received my package exactly 3 weeks after ordering, and when I saw the ring I almost cried. The ring is perfectly the same with even those vintage features that reproduced the original copy. Gaetano is truly a talent at what he does. Thank you so much.
Marco Venier
I decided to buy an engagement ring online, trying to save something and buy directly from the factory. I googled the most named companies and decided to contact GC Manufacturing Jewellery. From their site I sent a request for information on whatsapp. The owner answered me directly the same evening. I asked for many details to be sure of my purchase making me feel very comfortable. I received my ring today directly at my house in Cape Town. I am really very happy both for the perfection of the details and for the 24/7 service that Gaetano Costa has reserved for me. I recommend GC Manufacturing for the quality, price and service, but especially for the touch of a magical Italian jeweller. Thank you.
Stanly Mthembu
Lovely rings, extremely happy with the all process. Gaetano Costa guided me to purchase the perfect ring. This guy did the magic and my wife she very happy. Am really glad I found this company. Thank you very much.

I bought a ring from GC Manufacturing and it was all that they said it would be. the workmanship was great and the people I dealt with was awesome. The best part was the service and the value I got. I would recommend them to anyone.
Elizabeth Mnomiya
Extremely satisfied! I communicated with Gaetano all the time directly on Whatsapp. I had some doubts about moissanite and he explained everything step by step, when I received my set of rings I could not believe my eyes. From the order to the shipment I received only excellent service. Thanks once again GC Manufacturing.
Jarie Spantan

What a wonderful experience my ring delivered from Johannesburg to Cape Town in a matter of days!! The quality and workmanship exceeded my expectations!I highly recommend GC Manufacturing jewelers to anyone who wants value for their money.
mehleli nicko
I received my fiancé ring yesterday and she over the moon. Thanks for the wonderful service and will see you back for my wedding rings. Thanks to Gaetano and his team! Thank you very very much!
Lerato Dlamini
Firstly, their prices are highly competitive, coming in well below what jewellery stores quoted me for equivalent stones / rings. Secondly, Gaetano always offered highly valuable and objective advice. Lastly, Gaetano was extremely communicative throughout the whole process, which made it much simpler and stress-free than I imagine it would have been otherwise. I recommend that all South African who are in the market for engagement rings should go to see GC Manufacturing Jewellery. Thank you!
Kevin Pheko
I must say that I have no words to describe the excellence in Gaetano's work. I bought my ring in 2016 and even today it is cleaned and maintained for free every year. I recently had an old ring from my mother to repair and I gave it to Gaetano to have some modifications, the result was amazing. I recommend GC Manufacturing to anyone. I'm super impressed.
Ross Reid
Thank you for the amazing ring. The service and quality is incredible. Thank you Gaetano
Talha Suleman
Costa is awesome, had our wedding rings made by him and all my wifes jewelry.Often refer to him, never had an issue and always on time. His quote was also the best. Definitely recommend him.
Cindy Pretorious
I met GC Manufacturing Jewelery on facebook and asked for some quotes for diamond rings. I immediately received an answer and started chatting with Gaetano. He answered me at any time of the day even late in the evening, I must say I was not such an easy customer, but his professionalism really impressed me. I received my ring today and was blown away. 5 stars are not enough to define the quality and its service. Thanks a lot GC!
Tyrone Sarkis
I bought the engagement ring and recently the wedding rings for our wedding. I am extremely satisfied especially with the free maintenance service. Recently my wife has enlarged the ring without paying anything after years from the first ring I still get free assistance. I am truly amazed by the service from Gaetano and his team. Thank you very much!

Afurakan Mohare
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
Sulaiman Jinnah

Jason Pollard
Unfortunately 5 stars are too little to describe perfection in both service and quality. I recommend Gaetano Costa and GC Manufacturing Jewelery you will not regret it. Thanks again.
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!
Jade Swart
After getting many quotes from different jewellers, I finally decided to buy the wedding rings from Gaetano Costa. I could not have made a better choice, impeccable service (even during this dark period), the quality of the products is truly remarkable. Thanks to Gaetano and his team!
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
Michelle de Witt
This is the quickest and most exquisite experience I have ever had and the quality is fantastic, I recommend them to the moon and back! My expectations were far exceeded. Thank you very much for taking my breath away. Please note the camera does not do this piece justice🥰
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 😀
Liphoko Mothibi

Lwazi Makibelo
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.

Thank you so much! We will treasure these forever! We will be in touch in a few years for an anniversary gift :).

Abrie van Wyk
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:)
Connor Noah Harty
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

Ike Ditshego Rakoto
Excellent service from Gaetano, even after a year He still polish our rings without a hussle, All my friends had to come get their rings here after the service I got. Great Job Gaetano.
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.

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

I'm very pleased with the service I received from G.C manufacturing. My wedding ring is stunning and for the price quoted it's unbelievable. Thank you so much. I would recommend G.C Manufacturing to anyone looking for quality engagement\wedding ring for the fraction of the price you would get from retail shops.

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.
Teresa Pinture
