Outstanding craftsmanship. His work is of excellent quality. There is something to suit everybodys wallet and taste. I highly recommend and thank you for the most beautiful ring G x

I am so pleased with how it looks and feels. It totally is top of the line yet I am not hesitant to wear it every day. It is pretty and dainty and I love that I can stack it with other rings too (dress it up or down). Definitely the best place to buy diamond rings without losing an eye and a leg, with the best service and quality in South Africa. I received as well my complimentary gift. Thank you! I will be putting that towards my next purchase :)

The team at GC Manufacturing Jewellery is incredible. My husband had zero clue about diamonds and rings when he started the process of looking for an engagement ring. G.Costa helped him every step of the way, giving him many options and ideas, all within his budget. We also designed our wedding bands with them. The detail and quality are impeccable. Highly recommend!

Gaetano helped me choose a really good quality diamond for an engagement ring. I visited the factory a few times to discuss designs and stones and the staff were always very helpful. I found them very knowledgeable and had very good communication throughout the diamond quality and manufacturing stages. The final product was a really high quality ring and my partner loves it.

I cant begin to express how amazing my experience with Gaetano was. He and his team are impeccable! He completely understood my vision and helped me at every point of the design and production process. My ring is incredibly stunning and the price was unbeaten!! Look no further for the best diamond ring company around.

We purchased our engagement and wedding rings from GC Manufacturing Jewellery, the customer service and quality of the rings is excellent. Weve continued to purchase pieces of jewellery even though weve moved abroad . We also recommended many family members and friends.

Had my engagement ring and later a matching wedding band made by GC Manufacturing Jewellery. I was so amazed by how gorgeous the engagement ring looks, a photo just cant justify how much it shines brilliantly. The service we received was second to none. Thanks to Gaetano and all his team

Quality and service were truly exceptional. The ring was handcrafted and exceeded all our expectations and the price was fantastic. Gaetano knowledge was truly exceptional an gave us confidence in choosing the prefect diamond. Would have no hesitation in recommending them for your diamond rings. Once again thank you for all your help and wonderful craftsmanship.

What incredible service! The people at GC Manufacturing really take the time to understand what you want and make your dreams come true!!! The whole process from start to finish is impeccable! And Im beyond happy with my beautiful ring! 😍

Highly impressed with their quality diamond rings and generally with the all service. I raccomend GC Manufacturing to everyone. Thanks

Theres no place that will provide the luxury experience the way Gaetano and his team do. My experience was incredible from concept to the arrival of my beautiful ring and I cant stress the convenience of it all! I proudly look at my beautiful ring everyday and trust that I chose the perfect company to work with.

Me and my Fiancé love the rings. They turned out exactly as I wanted. Mr Gaetano was very friendly and helpful throughout the whole process. Helping me with what style works better with what size gem and of course the size of the rings as well so that it fit perfectly on proposal day. Will definitely be coming back for my ring and other jewelry in the future. Highly recommend.

After spending several weeks asking for quotes and discussing designs for an engagement ring, Gaetano & team managed to not only make the ring to my exact design specifications, but do so in a week, and for two thirds of the price of the closest other quote I received. The after-sales service is also second to none. Best of all, the ring is absolutely breathtaking!

I have recieved the ring from the courier service. The ring looks amazing!! Thank you ever so much for this, I know my partner will love it. I Appreciate the patience with the emails and I will definitely be keeping GC Manufacturing in mind for future jewellery purchases. Thank you again!!

This is our second purchase from GC Manufacturing Jewellery, the first being my wifes engagement ring many years ago. Well Gaetano did not disappoint! I purchased my wife an amazing pair of wedding rings set in 18ct white gold! GC Manufacturing Jewellerys customer service was second to none and the quality and value was outstanding!!!

What an incredible experience from the exceptional customer service to the exquisite styles and absolute brilliance! Thank-you Costa for the unique and absolutely beautiful diamond ring! BEYOND AMAZING 10 STARS

Hi Im very happy with the service i received, i had a problem with making a service booking for my wifes rings, due to bad internet connection, i phoned The Diamond Ring: company and the lady at reception helped me very kindly, she was very helpful and professional in assisting me. Thank you Brenda you were awesome 👌

Professional and efficient. I ordered my diamond ring 5 days ago and today I received my package. I am impressed with the quality of their rings, thank you for all your work.

This is my second ring with GC Manufacturers. I must say Gaetano never disappoints, I couldnt ask for anything more. The quality is amazing nothing like what you get at the other jewelery stores. Your work is amazing...thank you so much.

A custom piece that came out beautifully at an exceptional price. The after sale service its a real bonus. Highly recommended.

I had my ring remodeled from Gaetano. I was amazed by the result of the new ring. Thank you very much. 😊 Highly recommended!

Am really impressed. My ring was sized in 15 minutes. Great jeweller. Thank you.

Gaetano is one of the godfathers of the diamond industry in South Africa. Sourcing quality stones worldwide, is a risk that can be mitigated if you use a professional; and few have a network like GC Manufacturing Jewellery. I’d recommend without hesitation and will be purchasing again soon. Gaetano Costa; a name you can trust.

Gaetano Costa did a wonderful job with my engagement ring! An absolutely beautiful round cut brilliant ring with incredible service as well. Free resize in a quick turnaround - very pleased, highly recommend!!

After looking at several other jewelers, we came across GC Manufacturings website. The site was extremely easy to browse for a ring and book an appointment. By far the best site I have used where you can easily compare the stone sizes and precious metal colours.Gaetano was very efficient and didnt try to just upsell for the sake of it. He genuinely cared about what ring would look best. The rings were finished on the agreed date and collection and fitting was a breeze.

Dont go anywhere else. This is the first and last place you will need to shop. You dont need to do any research or shop competitors, just speak to Gaetano, he will help you. They are the best! Thank you.

Amazing service. Best quality and service in South Africa. Thanks Gaetano Costa for the beautiful diamond ring. 😍

Thank you very much to Gaetano Costa and team for this wonderful wedding ring that we received in perfect condition. We are getting married on 27th of March 2021, after not having had contact for 42 years. The ring is perfect, and Karin is very happy. Regards, Daan & Karin Smit, Port Edward, KZN2 Months later we had a small problem with the ring. We notified Geatano, and within 5 days the ring was collected, repaired, and delivered back to us. All at NO cost to us. Now THUS is service. Thank you once again. You have gained a customer for life.

They are perfect and exactly what I’ve come to expect from GC Manufacturing Jewellery. Thank you so much for your service and for the beautiful gift!

Excellent service. The lifetime warranty is not a lip service ir marketing strategy. I am happy with the service received and would recommend GC Manufacturing to anyone looking for a tangible value for moneyMK

From the moment you enter the doors at GC Manufacturing Jewellery you know you are in the hands of true professionals. I cant praise these Gaetano & Kosta enough and wouldnt hesitate recommending the team to anyone and everyone I know!!

Gaetano was very helpful throughout the process; from the first inquiry straight through to the delivery of the ring. I was delighted with the manufactured ring and it looks exquisite. Will recommend them to anyone.

Beautiful collections of diamond rings and wedding rings , excellent customer service with the utmost professionalism.

Thank you for designing the best and out of this world engagement ring for my fiancé. I can’t wait for Gaetano and his team to design our wedding bands.

Gaetano was an incredibly helpful and professional jeweller who helped me propose to the love of my life with the perfect ring. I would not go anywhere else.

Trustfully, fast service and convinience. One of the best in this country.

Was recommended The Diamond Ring from a family member. Was previously a sceptic about purchasing diamonds online. However the team at GC Manufacturing Jewellery helped put my mind at ease 100%. They have diamond rings on their platform ranging from top to bottom in terms of quality & price.I simply told them what I wanted to spend and what size I wanted. Highlighted a few I had in mind & Gaetano got back to me very promptly with advice and which diamond he would recommend.Within 7 day I had my diamond ring.I 100% have & will keep recommending the team at GC Manufacturing Jewellery to all my friends & family.

Thanks for fixing my ring, was a great service. I will be back soon. Thanks a lot.

Best quality Engagement Rings. Highly recommended!

In 2020, I purchased a wedding ring for my now wife. I was so blown away by the service and quality of work I ended up buying two rings.Today, a year later, I am back getting the rings cleaned and restored because they offer that service for FREE, once a year, for the rest of YOUR LIFE.Gaetano Costa, the owner and designer is a true artist and works with an amazing team. Respect.

10 stars Quality and Service. Highly recommended!

Hey everyone, I really recommend GC Manufacturing Jewellery. My partner and I went to a few places and we were really pleased and impressed with Gaetano service and how honest he was. The whole process is very professional and my ring is perfect and the quality is 100%.I designed the ring and they are very accommodating and made it exactly how I wanted. Thank you!

Highly Recommend!!! I spoke with Gaetano over the phone and sent him some pictures of the engagement ring I wanted. I live in Cape Town so coming to Johannesburg was a mission. The ring was made and sent up to me. Its amazing. Great service, quality workmanship. 10/10.

I was a bit afraid of how the actual ring would look when it arrived. But when I opened that box, I was SO extremely thrilled. It was so beautiful ... so stunning. Incomparable to all the other rings I was able to see in real life here in my town. It is PERFECT. Thanks also was the lovely gift. I will definitely come back for more. Thanks

We got engaged in Phuket and it was kept a secret from my loved one Astrid. I took a design off The Diamond Rings web, and made a few tweaks which I thought shed love! GCs team manufactured it absolutely perfectly and with a tight deadline to meet our flight departure date all hush hush!If you are discerning, and seek a quality craftsman and team who are passionate about the detail they lovingly assist with in guiding one to have a perfect piece manufactured, then go no further than this company!After sales service is exemplary and my wife sends it in for a professional clean and service annually!

Great craftsmanship, service and experience. Highly recommend.

I cannot begin to thank Gaetano for the excellent craftsmanship and phenomenal service ! This is my second order and I can assure you there will be more . You are a true artist ! And an absolute blessing! Thank you so much for the extraordinary measures you went to , I cannot believe how quickly I received the rings , and I’m still so amazed at the quality .

I order my ring online and the service was really great. My wife love the ring and am very happy with the quality and service. 10/10 service.

A huge thanks to Gaetano and the team at GC Manufacturing Jewellery for creating a stunning engagement ring for my big day. We were looking for a simple but unique design and Gaetano went above and beyond, from walking us through selecting a beautiful diamond to even posting out a 3D printed mock-up of the ring. I recommend GC and will be definitely returning in the future to do the wedding rings.

Best place to buy diamond rings online. Excellent quality and great service, really an amazing company. Thanks for the amazing gift as well. Thank you.

I recently had to have my wedding band and my engagement ring resized. I received very professional service and all my needs were attended to. Brenda and Gaetano Costa are friendly and very helpful. I recommend GC Manufacturing.

Awesome service and great staff. Thank you

My wedding ring was collected a day before wedding day, I only saw it in the morning of the big day.... brave I know😛nonetheless I love my ring. Exceptional quality, thank you.

Absolutely exceptional service and an exquisitely beautiful ring at the end. I brought in my own stone and Gaetano was more than willing to use it in his own design and crafted an amazing ring that my fiance loves.

These guys are awesome! I was able to find exactly the right ring for my fiance. They were very flexible and worked with me to find the perfect ring in my budget. I highly recommend for anyone who is searching. Top Quality service!

This is our second purchase from The Diamond Ring & GC Manufacturing Jewellery, the first being my engagement ring many years ago. Well Gaetano did not disappoint! I purchased now an amazing eternity ring set in 18ct white gold ! Gaetano customer service was second to none and the quality and value was outstanding!!! PS:After many years from my first purchase, I still receive the free maintenance and restoration service. This is really a great bonus!

Affordable luxury, and outstanding designs. 5star workmanship that I highly recommend : best manufacturing jeweller in South Africa by far. Cant wait for my next ring:-)

Got married 2 days ago... my ring was perfect. Mr Costa is the best in town.... the engraved part was the cherry on top. Though my words were long but he managed to engrave them to fit ....The admin lady is the best in what she does. She beautiful and well spoken. Their time frames were amazing and unbelievably quick. Cant stop staring at my own ring admiring the beauty... more perfect in real life. Men if you want to see your women happy buy them a ring from GC 😊😉. Happy customer... anello perfetto. The ring gets 10 stars...

I purchased an engagement ring for my girlfriend and was absolutely stunning!! I contacted Gaetano again to create custom wedding rings and they were definitely worth the wait! They were perfect in every way and the attention to detail of the GC Manufacturing Jewellery design team is just amazing! This is my second time buying jewelry from them and they exceeded my expectations each time. I appreciate the passion and expertise of the team! Thank you very much and my girlfriend (soon future wife) couldnt be happier!

After searching on numerous sites I settled on GC Manufacturing Jewellers as their website was very easy to use and we could see exactly what we were buying (other than viewing it in person due to lockdown and location). I made the order and hoped for the best.... I was pleasantly surprised with great after sales service and quick responses. Mr. Costa You have a great company and being able to supply this type of service in these difficult times is very encouraging! Thank You

When I saw all the 5 star reviews for Gaetano I thought it might be too good to be true. But shopping for our wedding rings with him was the best experience.Firstly, the website is so well designed and easy to use. Great transparency in terms of what you’re getting and the prices. His online booking system is also great.In the end we decided to visit the store for a consult and his service was exceptional. He offered good advice and had our rings ready in less than a week. Furthermore he offers a lifetime warranty and free yearly maintenance of your rings.Will definitely purchase from him again

HIGHLY recommended! If I could give 6 stars i would. Absolutely Fantastic service! I literally messaged GC this morning before the birds were up. Being a typical Joburger I wanted a ring for my fiancé and wanted it to happen like yesterday. I got a response a few mins later and my request was met with quality, speed and such generosity. I received a beautiful necklace as a surprise gift with my order and I LOVE it. The product was a Seattle style 9kt white gold ring and it was even better in real life than on the pics online. Not to mention the last minute request to engrave a special message on the inside = met with stunning result.

We are more than impressed with the amazing service! Thank you for making the sometimes traumatic experience of engagement and wedding ring purchase so simple and easy! The quality and perfection of our rings made us more than happy. Thank you again for your tireless perfection. Excellent service Excellent price and amazing diamonds.
