Nice brilliant reflection in this stone. Not overly dark. Beautiful violet color. Very rich looking stone. Very slight to very very slight inclusions present when backlit with magnification. One of the best cut spinel on gemrock site.
This is from Luc Yen Vietnam. This deposit is in the same marble layer that runs through Laos into Myanmar.
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.
