As part of the gem hobby for me is to show the forum & people within the business what I believe is good representation of a gem stone. This is red spinel, all burmese & what is labeled as red/orangish in color, VS class stones in gold, item is 2" x .6" tall & wide & recently gold work upgraded by John. The burmese material is fluorescent very well under UV light, which usually means low iron [Fe] similar to burmese ruby. the pics 1-2 are daylight, 3rd pic is in UV light. Im reading in posts on line that more of stones like these and alexandrite are showing up as low heat treated to try & remove unwanted color from the material, usually heat is not used on these stones but this is being done at the mines even before the material goes to the cutters, another way to question the purity of what is out for consumption-steve... dancer5... omg... book11
