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 A.

07:39 09 Dec 19

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 P.

10:06 29 Nov 19

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.

GC Manufacturing Jewellery got my diamond ring business because they were honest, knowledgeable, and nice people. I made several trips to their store, and each time they were very helpful. I even brought another diamond from another store to make comparisons. I noticed a big difference in quality and design of GC Manufacturing Jellewery they create outstanding and exclusive jewellery. I can’t thank them enough for helping me in designing my ring and guiding me through the process. I had faith in their expertise from beginning to end as i had been referred to them by my brother who also had a great experience with them . I just really appreciate how they conduct business! :)

Natasha L.

08:43 15 Nov 17

Thank you Gaetano for your excellent service!!! My ring was ready for collection after only an hour. And he charged me next to nothing for it!!! I had taken my ring to SO many jewellers in Sandton and the quotes I received for resizing my ring was ridiculous. Gaetano charged less that a quarter of that AND it was done within minutes. Thank you thank you thank you! ♡

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.

Lara F.

Thank you so much for the amazing service. I preferred a weeding band on a Thursday evening. I was called the next morning asking me if I wanted any engraving done as this was a free service. Was call again Monday morning to let me know the ring was ready. I will definitely recommend to anyone. Friendly and amazing!!!!!

Gaetano is a star � Honestly! My husband and I picked rings off his catalog for our wedding and boy were we beyond pleased. He is very friendly and attentive. He’s also good at meeting your budget without compromising quality. I would definitely recommend his gorgeous rings (and jewelry as a whole) for a unique and classy touch. Thank you so much GC manufacturing �

Jessica Ma Poon We were so glad to find Gaetano and meet with him to discuss my dream ring. He was very helpful and professional. Knowing that he was making my ring made us very comfortable as he gives his personal touch. My ring is more than what I expected, so perfect and great craftsmanship. My ring is stunning, I love it and am so ecstatic! Thank you again for my beautiful ring Gaetano. I would definitely make use of our services again. Anyone looking to make a ring, I would definitely recommend Gaetano. :)

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.

Gaetono is the best, I had an idea of what I wanted and his design and workmanship is even better than I imagined and he made my fabulous ring in record time! Have old tired designs reset, or make something brand new - it will always be original and well priced if you manufacture it with GC Manufacturing! �

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.

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 :)

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 PROMISEread more

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.

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 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.read more
