TOP BLACK JADE ROUGH B+++
Top Black Jade Rough B+++ ready for a crafts person to carve or make jewellery with. This is genuine true black nephrite jade from Cowell, South Australia (the best Black Jade in the world). This variant of jade is becoming more scarce and is used, in particular, for carving into super-lustrous pendants and jewellery. One of the toughest rocks on the planet. The Black colour is from an inclusion of Iron of up to 8%. This is one of the best specimens from a lot of 1000kg. You can still see the old mine grading marks with the grade and initials of the person who graded it. When we procured this lot we were told it came out of an old rusted out container from the 70’s.
To be honest I was hoping to save this one for my self. The stone has one cut face and is flat with some colour near the rind at one end. Some pics are with wet and dry stone to show the quality of colour and reflection. This stone is best polished with aluminium oxide then diamond to get the mirror finish.
