Very nicely cut stone with 0 window.   Face is large for the size and not a heavy bottom adding extra weight.   This stone will not sit high in a setting making the ring more prone to twisting on the finger constantly.   This is about as good as it gets for cut spinel for a gorgeous ring stone setting.   Would be just as suitable in a hanging pendant.
Prices for this color are sometimes in the tens of thousands per carat.  I bought a lot of stones from one person during the pandemic and got a great price to offer these to you for a far more reasonable price. I was never able to buy them at $5000 to $10,000 per carat before because I found it crazy to do so. When i started bargaining hard for this lot I broke down and spent the money because the colors were just too pretty to refuse and I know the price I could offer would be a bargain over what I have seen in the past.  Relative clean spinel VS quality and eye clean   Inside no inclusions to be seen with the naked eye.  Extremely brilliant reflection.  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.  
If you check other sites you'll see stone one carat less than this of the same quality prices over $35,000.  
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.
