This is currently my favorite ring. Its gorgeous. People don't know its not real. The stone is slightly darker than in the picture but it does look that color in sunlight. When I first got it my mother in law commented on it saying "i thought you lost your engagement ring?"
Of course my husband blabbed his mouth that it was fake, but no one would have known the difference had he said nothing.
The thing with lab created sapphires is that they are essentially real. They are exactly the same as natural sapphires except that they are created in an artificial environment. Jewelers of course can tell the difference, but if you want something beautiful for not a ton of money, this is the way to go
