Should I get a full cert for a 5-figure unheated sapphire?

I've written already that I think we"ve found the discussion on how much would the stone have to cost for you to do a cert.

My question is: Given that the price of the unheated sapphire is 5-figures (over $11K), should I pay the extra to have a full cert (ETA: to have geographic origin determined)? I do trust the GIA cert. The appraiser, who sourced the stone for us, is helping us with the setting. He provided the following details on the sapphire:

"Oval faceted, natural, unheated blue sapphire has been certified by GIA, is 9.67mm long by 7.87mm wide by 5.92mm deep, weighs 3.74 carats and has no color reaction to long-range, ultra-violet illumination. It is eye clean (loupe grade SI1 clarity that is VS2 clarity on GIA's Gem Clarity Grading Scale) and well-made. The table diameter is 43%; the crown angles are 34 degrees; the crown height is 19%; the polished girdle is medium to slightly thick; the pavilion depth is 44%; the total depth is 75%; the culet is closed; there is no color zoning.It is a translucent, moderately bright, strong, blueish-violet color (GIA's GemSet bV 5/4)."

After seeing this stone, I'm emotionally attached to having an unheated sapphire on my ring and having THIS unheated sapphire for my e-ring. Now, my emotions are telling me perhaps I should get the full cert. Would it be a waste of money?

I don''t really see the point in getting a cert just to try to identify the origin of the stone, especially when you already have a GIA cert, but its your money.

I just don''t see what extra you would gain from getting another cert when you already have the GIA. Now an appraisal on the other hand...you should get one of those anyway for insurance purposes.

If a Ceylon sapphire has a higher premium than another sapphire from another country, even if the color is the same, I would get a cert. I'm not sure if there are premiums on Ceylon sapphires vs sapphires from supposedly lesser quality countries. I've seen some Madagascar sapphire that was just as gorgeous as Ceylon though.

However, if it were a Burma or Kashmir sapphire, I would definitely want an origin cert. Those do hold premiums by origin. I really think Burma and Kashmir are in a class by themselves.


Kashmir
Burma
Ceylon

rank as 1,2 & 3 on the list of quality for sapphires in that order.
