Extremely difficult to come by. This is the very best ox-blood color! It cannot get any better than this. A rare nature wonder weighting 7.45 ct., FINEST, DARKEST, ox-blood color, excellent, oval cabochon cut with high dome and rounded bottom, excellent texture and polish from the Japanese Sea. The bottom has some whitish veins, which is very normal for this kind of material, and it is also an indication that the piece is of natural color, NOT DYED. A fantastic piece, of great size destined to make a most unique and mesmerizing Mars talisman.
