About 7/8 inches across and 2 1/8" long with 1 3/8" of that being the dangle below the ear.
Marino (1932 to the 1970's) vintage silvertone - I believe it is Chrome plated as it has the look, weight, pitting and feel of chrome - silvertone ball swinging heavy pendant clip earrings.
I would say that these earrings are from the 1930's or 1940's to the early 1950's as they seem very Art Deco Modern to me when chrome was all the rage.
Due to the pat.# on the clip, we know that these earrings were made in 1934 or after.
Patent number 1967965 was issued for the type of clip design in 1934 and is stamped on the inside on clips.

"MARINO" is stamped on the outside.
There is quite a bit of normal wear to the chrome so these are being sold at quite a discount.
