@Tejas Thank you kindly for your reply and for your hieroglyph translation. I was not aware of the scarcity of silver in Ancient Egypt; that's interesting. I was thinking/hoping the ring could be an example of Egyptian revival jewellery from the late 19th-early 20th centuries, wherein ancient scarabs were set into new jewellery. However, a closer look at the silver hallmarks dates the setting to the 1970s (if I've read them correctly).
@antwerpen2306 I've attached photos of the inscription here; unfortunately, these are the best photos that I could capture with my old phone:
I would not be too devastated if the scarab itself turns out to be a 20th-century replica. If anything, it will further fuel a desire to acquire a genuine ancient scarab.
