Designer Signed Sterling Silver Cultured Pearl Clip Earrings

From a designer whose signature I can only guess at - Ideofeo or Idoreefeo or something like that (as pictured), may I offer this pair of clip back earrings in Sterling Silver (hallmarked as pictured). In a circular "tube" design (though the pieces are hollow), the earrings are true left and right pieces featuring a 5.5mm cultured pearl at the (okay) Pac Man-like mouth opening. Height is 1-1/16"; width is 1-3/16". Combined weight of the pair is 21.8 grams. Condition is perfect with no problems I can spot. Clips work fine and have a good hold on the ear. Definite designer earrings as the estate where I purchased these beauties - well, it seems she only shopped at Neiman Marcus!
