Here's something very curious. A vendor on ebay has a spinel for sale with a "cert". The "cert" says "evidence of heat enhancement has been found in this stone."

I have read the GIA articles on heating spinel from Tanzania, but this is supposed to be a Burmese stone. I've written to the vendor about this and will post his response here.

HERE is the auction in question.

:D lol, could hardly read the cert either, where is SPL lab? on the cert is has "evidence of heat enhancement," but in his/her description it states: "none" for treatments-guess the seller made a mistake in the description of the stone.

looking forward to hearing what the seller has to share with you, jason, about the treatment of the stone since it supposedly is a burmese spinel.

by the way-how do you like your new "eyeballs?" i have them as well-for about 9 years now-thanks to myopia or nearsightedness from cataract surgery (pita), use them mainly to drive the car or watch colorvision-. :wink: i've sat and stepped on mine countless times, lol. (and misplace them frequently)

Err...stating that something is heat treated on a gemstone report is more than a typo. A typo would mean it was spelled wrong, not a completely wrong statement.

And is that usual for gemstone labs to make massive errors like that? No quality control?

Sounds like he owns or at least has a lot of influence with the 'gemlab'

either that the lab is real and made a right call

We all know by now that spinel (at least some) are heat treated on a regular basis.

I see Burmese Spinel rough that appears to be melted together. The treaters say that often it cracks with the heat and it is usually a waste of electricity.
