“Thank you all, absolute legends!
Colin, thank you so much for sorting me out with tip top advice, and some additional much-needed guidance. Thank you for sourcing the perfect rock!”
I’d like to express my thanks for your professional assistance when I bought a 1,00ct diamond for my wife. You advised me on how to save money by going for a particular colour and clarity, while not compromising on the size of the stone. My wife and I are very satisfied with our purchase.”
“In February of this year my fiancée and I bought a top quality diamond through your website. We found the layout easy to follow and the response from you and your staff to be prompt and courteous. We are also thrilled with the lovely ring, designed by your wife, Olga. I would recommend you to anyone.”
“I made the decision to propose to my girlfriend, but then I realised that it wouldn’t be that simple – a ring was needed! There are so many jewellers in the phone book, what was I to do? So I googled (as one does!) and came across CG Diamonds’ website. It was a leap of faith on my part, as I knew nothing about diamonds. . . so I placed myself in Colin’s hands, and am happy to say that it was the best decision I could have made. My girlfriend is now my future wife and is proud of her beautiful diamond ring designed by Olga.”
“Baie dankie aan Colin en sy span by CG Diamonds. Hulle het ons so mooi bygestaan in die moeilike proses om die perfekte Diamant te kies. Hulle pryse is ongelooflik en die handewerk is uistekend!”
“I can recommend CG Diamonds to anyone looking to buy a good quality diamond. They are very helpful and always go the extra mile to ensure customer satisfaction. Although their diamond business is web based, one can pop in at any time to meet Colin and Olga in their Waterfront store.”
“Beste pryse in die land. Ek en my verloofde wil net dankie se vir die uitstekende diens en sal hulle enige tyd aanbeveel. Colin het met ons sy kennis gedeel en saam met sy vrou , Olga,het ons die perfekte ring ontwerp vir ons spesiale dag. CG Diamonds is eerste in sy klas”
“Just to provide you with some feedback after our recent purchase of an oval diamond from you – we appreciated the personal touch and all the trouble you took, sourcing the perfect stone from your factory in record time. We were made to feel completely safe and comfortable buying over the web, and my wife is the proud owner of a lovely ring, set with an E colour diamond, the envy of all her friends!”
“Dankie, dankie, dankie CG Diamonds! Ek het my droom ring gekry. Ek het lank gesoek na die regte plek en die regte prys. Die personeel was baie professioneel en het ons baie geleer van Diamante. Ek sal almal aanbeveel om hulle n kans te gee”
“Colin and Olga Goodman are the perfect team. Colin gave me the confidence to buy a diamond and Olga designed a lovely ring – exactly what we wanted! They are very professional but still managed to make me feel comfortable while making such an important purchase. Thanks to both of you.”
“Colin Goodman was a great help to me and my fiancée when we purchased a diamond from CG Diamonds earlier this year. He explained the importance of the diamond Certificate and walked us through the intricacies of diamond grading. He helped us choose a diamond that was within our budget, but was still excellent value for money. We chose a design for the ring which was hand made by Olga’s team of master goldsmiths to the highest standards, making my fiancee’s dream of the perfect engagement ring come true.”
