I have a pure yellow colored Sapphire, is this a good stone?

Question

It's 3,2 carats (est 10x8mm) with traditional oval cut. The color is pure yellow, it have a dark tone if I put it in the shadow, but I just can't find any hint of orange or green. And I can't say it's a golden-colored either because the hint of gold color only appears when I took it in a shady room, or when it's twilight.

The gemstone is so much like this:
If there's enough light in the room, it'll looked like this: http://www.gemselect.com/other-info/graphics/yellow-sapphire-ceylon_2.jpg
If the light is dim, it'll looked like this: http://www.venusjewellers.in/images/3.5CARAT%20YELLOW%20SAPPHIRE.jpg

I know little about BE treatment, but I now that if your Sapphire got too much hint of oranges or golden, maybe you have the BE treated one. What about this? Do you think it's a good stone?

Most yellow sapphires available in the market today are either Beryllium heated (Be) or otherwise thermally enhanced. If your yellow sapphire is Natural & Non-heated, then it's a good stone. If it is possible, you must get it certified by some reputed gem-testing lab which will add to it's value and assure you of authenticity.
