This DVD is a visual feast for opal lovers. As a European customer said about the cutting of Princess Mary: "da fallen jedem von uns unter Garantie die Augen heraus!" which means roughly ".. guarantee everyones eyes will fall out!". Most people never get to see gems of this quality, let alone see them getting cut from a difficult piece of rough with such exceptional skill.
Another customer said.. "I just reviewed the DVD you sent and it was very well done and the cutter was very very good. Elisabeth Pal ahd been cutting opal for some time and it showed. Her steady hand at splitting that huge opal to get the Princess Mary stone brought goosebumps on my back. I have never sliced an opal that big. The rest of the DVD was very well done.. Again, thanks for allowing me to see the learning process about black opal, not normally found elsewhere.
As outlined on the DVD. A black opal is a natural solid stone with a black or nearly black body tone(ie background appearance).
Whether an opal is a black or not can be determined by nearly closing ones eyes and squinting at the face of the stone. All colours are ignored and the overall body tone (blackness level) can then be seen.
When this is compared to the scale of blackness below it is possible to identify how black the stone is.
Only stones achieving values N1 to N4 on this scale are considered black opals - attracting the additional value associated of this class of opal.
