“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. The jewellery is absolutely stunning and so is the quality!! Would definitely recommend this as a go to jewellery shop❤️”
