Definitely!
(And at this size...I also admire the budget :mrgreen2: ).

I would love to see how such a giant sapphire looks like on hand.
Hopefully the OP will show us pictures once it is set.
It's just not often that you see a gorgeous blue 7 ct sapphire on hand.

The sparkle is more than the cut. It is also the clarity and/or transparency of the stone.

A stone with a precision cut can still lack sparkle if it is has an inclusion in the stone that can affect brilliance. Also, blue sapphires can be silky of which they appear velvety than sparkly. Some blue sapphires can lose some transparency when heated.

So for the sparkle, you will need a combination of cut, clarity, and transparency (crystal).
Congrats on your sapphire purchase! That's a big league rock. You clearly have a sharp eye and a great feel for the market.

I will also echo some of your comments on precision cutting of colored gems. In my travels in Asia buying gemstones I came to greatly respect the "liberties" often taken by local cutters to bring out the overall beauty of rare materials. And through trial and error of re-cutting native cuts, I found that often a precision makeover succeeded in making the stone LESS pretty!

It's important to keep in mind that the primary value factor in a colored gem is, well, color. If you can get even color AND brilliance, so much the better, but sometimes the two have an inverse relationship. (The same is true of colored diamonds - in most cases dialing up light return results in dialing down color saturation). In darker tone materials that can be a good thing, but altering angles on the pavilion to "precision" proportioning dictated by refractive index can also introduce extinction into an otherwise open, even color that performs in a variety of lighting environments.

Your gem appears to have the best of all worlds. And having spent time watching miners in Sri Lanka sifting for hours in gravel pits to come up with a few shards of corundum, I can attest that an untreated beauty the size of your stone is indeed a MAJOR treasure!

Thanks, everyone! It will definitely be set with a halo but I'm thinking a halo whether it is a halo with some pattern or a traditional one.

Thank Texas Leaguer for sharing your thoughts and your experience in Sri Lanka. :)

Thank you, Texas League for this very informative detail.
I did not know that a precision cut could, in fact, negatively affect maximization of color in a gemstone.

After 3 years, I’ve finally had a chance to have the stone set into jewelry. The stone is accentuated by pink and colorless natural diamond melees in a flower design setting.

That is sensational! I usually do not care for halos but that is both unique and lovely (a seldom-seen combination!).

Hi Acinon! The design was a collaboration between me and a local setter in Bangkok. I supplied the melees and I did want a ring that will not be too high when set. Thanks and be well!
