    The team at Sphere was absolutely amazing. I dealt with Bo personally and she was very accommodating. By showing her photos of designs I was inspired by, she was able to help me recreate a personalised ring in a week. All certificates were supplied including lifetime warranties on the items.

    Their store is conveniently located on the 1st floor of CentralWorld. The shop was very clean and they had a lot of beautiful ring options. We found beautiful engagement rings here, and they were able to adjust the ring to fit us perfectly on the same day.
    ​Extremely good customer service-the entire staff is really nice and friendly. I definitely recommend visiting here! We went to several stores and this one had an excellent selection, great value for money, and fantastic service.

    After checking several shops in the area, I expected CentralWorld would be more expensive, but it wasn’t!  Sphere Diamond had some of the highest quality stones for prices similar to much lower grade stones at surrounding shops. The staff is very professional. They gave me time and information to make the best decision for my needs. I had a genuine feeling of being a VIP but still comfortable. Thanks Sphere for a great buying experience. Our special day will be even more special because we love the ring we found here ♥️

    It was a wonderful experience purchasing a ring. The price was amazing, and the customer service was truly the best professional, attentive, and helpful every step of the way. I couldn’t be happier with my purchase and would highly recommend them to anyone looking for quality and exceptional service. 💍✨

    After experiencing 5-6 jewellery stores with exceptional service, I thought it couldn’t get better and sure enough it did!! The staff at Sphere Diamond were nothing short of amazing, kind and so so patient with our questions on the quality of the jewellery. When we ended with our purchase, the overall experience was so overwhelmingly satisfying.

    had such a wonderful experience at this diamond shop.
    Their service is warm, honest, and very patient-they explained every detail clearly, from diamond grades to the design of the ring.
