What is a "native cut"?

I was reading in another thread abt native cuts and had never heard the term.
What is a native cut and is it only for non-diamond stones?

And just like with diamonds, the cutting makes ALL the difference!

Here is a before and after picture of a sapphire I brought back from Thailand back in the early 2000's. I believe that this is allowed under forum rules, if now I will ask the moderator to kindly remove this post.

Great example of "Looks Like" size of a gem Wink.
Native cut tries to maximise the carat weight by creating rounded 'bellies'. In the case of diamonds - it is just extra girdle thickness and depth; that kills the brilliance.
The loss of brilliance tends to be more noticeable at the edges, making a diamond Look Like(tm) a much smaller stone.
So if the diamond say measures 5% smaller in diameter, it will probably look 10% smaller.
WOULD'NT IT BE GREAT IF THERE WAS A SYSTEM THAT TOLD CONSUMERS IF A DIAMOND LOOKS LIKE ITS CARAT WEIGHT SIZE?
