The starting bid for this stone is a steal of a price if you get it.   I should have started it out at $3000 because this stone is so top quality. 
Fabulous looking color and cut.   Very reflective and full fire stone.  Really a stone to keep admiring and would look fabulous in a ring or any piece of jewelry creation.  Spinel like this have gone very high into the tens of thousands per carat in the last few years.  I bought a lot of stones recently and got a great price so I can offer these to you at a fraction of some other sellers for the same quality.  
Relative clean spinel.   Inside mostly clean a couple crystal inclusions with magnification but stone is completely eye clean and better.   Extremely brilliant reflection.   Make me look at other stones and all of a sudden size doesn't matter nearly as much as color and cut.   I love this stone!   I've never posted any of these because I've been hoarding all the best ones.  I never really wanted to sell them.  I have quite a few I had collected.  Started buying more lately and the prices have skyrocketed. 
 
This is from Luc Yen Vietnam.   This deposit is in the same marble deposit that occurs in Myanmar Burma.   Luc Yen is only around 750 kms from the Man Sin deposit where the Jedi spinel came from.  I see a some calling dim burgundy red spinel Jedi which couldn't be further from the truth.  This is gorgeous looking spinel but it's not jedi it's just vivid red.   Jedi has a pinkish red glow.  This one is more like fine ruby.  
Luc Yen stones do not get treated.   No heat on the Luc Yen spinel.   Spinel do not respond to treatments like sapphire.  So rest assured this stone is 100% natural and untreated.   
Mined from under the rice fields in the alluvial gravels in the shallow valley near the original marble deposit.  Rubies and sapphire are also associated with this deposit similar to the Burma deposit.  I'm was a geologist before I became a gem enthusiast/gemologist.   My business plan is to bring the better quality gemstones to my customers at a better more fair price.
