Breathtaking was the first word I thought of when I opened the box and saw this ring because it simply took my breath away. I ordered a size N and it fitted perfectly. The central stone is one carat and totally believable. Again, as with the sapphire and diamond bracelet I've also reviewed the attention to detail is second to none. It looks so expensive. Please don't hesitate in buying any jewellery from Jian as I can promise you won't be disappointed.
