On offer here is a beautiful group of three brooches. the first is early 20th-century art nouveau with a large amethyst colour stone. the second is a vintage brooch I would think 1970s with a very large amethyst colour glass stone with a crane / bird carved into the back. and finally, we have a retro gold tone brooch with a large smoky citrine colour stone. these are all costume brooches,  the smallest is the art nouveau at approx 1.5 inches and the largest is the carved brooch at approx 2.5 inches. each brooch is beautiful on its own.
