Firstly, I would like to say a huge thank you to Robin and OCGems for all the help!
Prior to getting engaged, I was clueless as to how complex and detailed finding a ring that I knew my fiancé would love, could be. It can be as simple as going on line and buying the first ring that pops up in google, but that takes all the effort and uniqueness out of it. That’s where OCGems stepped in. And who better than an old school friend like Robin.
Their explanation and assistance through the process of diamond selection using the “C”s as a helping guideline, made me feel like I had known about diamonds my whole life. Not only that, but giving them a budget helped them find me the best option for me. A very personalised experience.
The level of professionalism and respect shown, despite being school friends, proves how they run their company.
I will forever be grateful for all that OCGems did in helping find the perfect diamond, and ring for the love of my life. Thank you

I didn’t have to think about where I was going to get the engagement ring for my fiancé. Robin and the team at OCGems were phenomenal. From explaining the 4C’s of diamonds, the great design and delivery. I couldn’t recommend them more!
Robin’s communication throughout the whole process was impeccable and kept me in the loop the entire time. I didn’t make the delivery of the ring easy as I was traveling from South Africa to Zimbabwe and had a short turnaround time between flights. Robin got the ring delivered to me discreetly without my fiancé having any idea!

Bengani: Robin is my childhood best friend. I remember when OCGems was just a dream of his, and its been incredible to be able to walk alongside him as he and Desmond made it a reality. So when it was time to find an engagement ring, I knew that Robin and Desmond could help me create something special. Just as diamonds are put through pressure to become beautiful, I’ve watched Robin and Desmond operate under pressure to create so many successful engagement stories. From the creation of the ring to the proposal plan itself, Robin was there every step of the way to help me create a memorable experience. OCGems and the team do not just create jewelry, they create stories of hope, inspiration, and lasting memories. I would 100% recommend anyone to use their services.
Alex: I am in love with my ring from OCGems! OCGems provides a whole experience to their clients and really work to make your engagement story exciting. I wholeheartedly trust and recommend OC Gems to anyone who is interested in creating a truly beautiful and unique diamond piece.

As soon as I heard a friend from school did some rings I had to get hold of him. Not only for a catch up but to support a falcon old boy!
Robin took time to get to know my girlfriend and asked some good questions when we were going through the rings. I managed to narrow the choices down to 2.
Robin carefully considering both options we got it down to one!
From the engagement we got to the wedding bands and from the wedding bands we got to finish off the other side with a matching band.
Five star treatment from him and his team! Looking forward to finding some more jewelry from OCGems in the future.
