Good value but can't predict the shape.
It came with a certificate and was as described with the exception of the shape. I am guessing that the seller uses one picture for a lot of similar sizes gems. I plan to use this one as a practice for gem cutting but was hoping for something a bit less irregular. Either way you can't really beat the price. The 2nd one I received was even better. It still was cloudy but was a lot more translucent and a much better shape. Its very pretty just not transparent.

Exceptional quality!
The appearance, quality, and color of this sapphire is stunning. I will be purchasing from his seller again! It came with white gloves, and a booklet describing other minerals as well as information about my purchase of a sapphire. My 11 year old Alexander has quite a collection.

Should hjave read the comments beefore buying
I bought two of these stones and the color is enhanced. I put the stone in boiling water and the purple dye rubbed off! They claim it is a natural sapphire. Who knows what I got.

Stone does not match certification.
I got a beautiful stone, but lighter and smaller than indicated in the advertisement, and also smaller and lighter than indicated in the certificate that comes with the stone. The stone I received was 27 carats, not 34, and no matter what angles I used to measured it, I could not get the size indicated in the certificate. The stone I got is beautiful, and I will facet it, but I did expect the stone to be 34 carats. We'll see how it ends up after faceting.

This is color-enhanced, not the natural color
The sapphire is a lovely color and a decent value for the price. The one complaint I have is that the description says it’s a natural blue sapphire but the gem certification card that came with it said it’s been color-enhanced. I’m not sure why the seller doesn’t disclose this as it is important information. Many people like the enhanced color but some want their sapphires to not be color-enhanced even if that means getting a lighter blue stone. Sellers need to truthfully disclose in their listings when gemstones are color-enhanced so buyers know exactly what they are getting at the time of purchase and not find out once they receive the item that it isn’t what they were led to believe it was.
