Brooch and earrings

I found a Schreiner stamp on the back of this brooch and earrings set. I searched for similar pieces but couldn't find a match. Can you help me identify them? Schreiner jewelry was made from about 1951 to the 1970s. It is probably most known for its distinctive and vibrant color combinations. Schreiner created a huge range of jewelry pieces including brooches, bracelets, and necklaces.
