Egyptian revival necklace that will look great with a plunging neckline or solid

Old Russian gold tone Egyptian revival necklace with 6.5” drop of the gold area. 16-18” with extension. Lovely pink color cabochon in the middle. Seems like it should have an established maker but no markings found. See close up of cabachon color. Can be worn as a choker with a neckline plunge, solid black or pink to finish off your great look!
