Vintage stamped sterling silver & polished stone triangle ring sz 7-7.25

Vintage stamped sterling silver & polished stone triangle ring sz 7-7.25. Striking stone is a simple but bold triangular shape. Accented with different scrolling shapes on either side of the setting. Stamped 925 on inner band. Stone could be some type of jasper, but the coloration is unfamiliar to me. No maker’s marks present. Good condition. Light wear. Imperfect shape to stone and setting. Light aging/oxidation, especially along the sides of the setting. Please refer to photos for additional condition details. Sits between a 7 and 7.25 on my ring sizer, but closer to 7. 2B
