Our opinion: This antique daisy-shaped ring is adorned with this magnificent 6-pointed star sapphire. This optical phenomenon, called asterism, is completely natural and due to the presence of crystalline needles within the gem. It is the talent of the lapidary that will reveal this unique optical phenomenon.
