Art Deco earrings with Rose cut Diamond Drop stud earrings

An 18ct yellow and white gold Deco era drop stud earrings set featuring a Rose cut Diamond, bead set with a single cut Diamond white gold bead set below a bar drop in each, test as 18ct, Valuer calls it Victorian, Circa early 1900s, based on the cut and age of the Diamonds.  I believe these to be later- circa 1930s- a set of Art Deco era earrings which used old cut Diamonds in the earrings.  The earrings are in a very good condition.
