Simply incredible! 17.82ct blue black Sapphire -UNTREATED!!!

This gemstone is simply incredible. It shows a silky blue black hue with full saturation, giving this sapphire amazingly rich color with an almost liquid appearance. The elongated oval cut of this piece has a low domed top giving it greater surface area and creating a sparkling kaleidoscope effect with its mirror grade luster. This is accented by proustite, a mineral that develops naturally in select rubies and sapphires that contains real silver, adding a delicate touch of shimmering metallic color to its display. It has substantial size, weighing 17.82 carats and measuring a whopping 18.5mm x 13mm x 8.2mm, and has a Mohs hardness rating of 9 out of 10 making it the perfect addition to your gem and jewelry collection. And it's UNTREATED! Sourced from Madagascar.
