I purchased a simulated white sapphire engagement ring and ordered a size 5 3/4. The ring was NOT true to size. I took it to a jeweler because it was so loose, and they measured it as almost a 6 1/2, so buyer beware! I like the ring, but have to have it sized down. I won't return it because I honestly wouldn't know what size to exchange it for! So size down if you're going to order from this company. They are a Chinese company too so it took two weeks for my item to arrive- not too bad but I had to contact them for the tracking since the one they emailed me did not work..
