Vintage 1980s DOrlan Earrings Round Clip-on Gold Tone

This is a pair of earrings made by DOrlan, featuring coloured cabochon rhinestones in a gold toned setting. DOrlan is a Canadian manufacturer that was founded in 1957 by Maurice Bradden, who had trained under Marcel Boucher. DOrlan produced jewelry for Boucher and acquired Bouchers company in 1979, continuing to produce jewelry using Boucher moulds. These are numbered 8307, and Im wondering if they might not be based on a Boucher design. Each earring measures 1 1/4 in diameter. They are in excellent condition with no missing stones or wear. These came from the estate of a shopaholic who barely wore much of what she bought..excellent quality.
