Untreated stones that are a desirable color and clarity are considered premium, but simple heat treatment is totally acceptable among fine jewelers, because all it really does is get you a deeper, brighter color in the stone.  What you don’t want is repeated heat treament or chemical treatment, which destroys the value.

For blue sapphires, a lot of people prefer a Ceylon sapphire with a cornflower blue color, while others prefer a deeper or darker blue color.  DH got down to 2 sapphires as final contenders for my ring.  A 3 carat cornflower blue untreated sapphire with very good clarity, or a 2.71 carat bright blue heat treated sapphire with eye clean/flawless clarity.  Ultimately he felt that the bright blue was more me (he was right!) and he wanted me to have an eye clean stone.  

My stone is a round cut stone, 8mm around or 2.71 carats, but I have a big size 8 ring finger, so I think it looks pretty proportional.

My stone is a true blue with violet undertones, which you can usually see under bright lights:

Outside or in sunlight, it looks more a true blue:

This is such a beautiful set! It reminds me of princess Diana’s ring.
