The XRF analysis of this Sasanian Gold Ring shows a composition of 74.97% gold, 23.96% silver, and 1.06% copper, corresponding to a gold purity of approximately 17.99 karats. This high percentage of gold underscores the ring's significance in the Sasanian or Mesopotamian period, as such purity was often reserved for the most luxurious items. The minimal presence of copper and a significant amount of silver would have contributed to the firmness and color quality of the ring, enhancing its overall appearance without compromising the high gold content, which is exceptional for artifacts from this era.
