Edwardian filigree necklace with enamel detailing on sale and black glass ovals

This pretty necklace features silver tone filigree links with white and black enamel filled flowers. Alternating links have black flat polished ovals with beveled edges. I think this necklace dates to the decades before 1930. This is not an overly long necklace as it measures a on sale bit over 14 inches or 36 cm. This unsigned beauty closes with a small box tab closure.
