This one is a “work of art”. I have seen alot of stones but never something so normal but as unique a sapphire as this one. The color is uncommon. It’s chocolate. Some parts are red like in Mysore type rubies. It seems the there is a “mother of pearl shell” inlay into the stone. The silver reflections are pearly and iridescent and takes a hexagonal shape. All natural. The gem is as if some artisan crafted this piece for us to appreciate. It’s one of my favorites!
