Black Star Sapphire and White Gems Atop Sterling Silver

This beautiful silver ring features a striking natural black star sapphire surrounded by sparkling white gems (likely white topaz but unsure of what kind of gem). The black star sapphire is natural through may have undergone treatments (heating or otherwise). Glad to answer any questions! Disclaimer: I’m not a gemologist—I’ve collected black star sapphires over the years and have never come across a lab-grown one, so my own research leads me to believing they’re natural, but please note that I’m not a professional.
