This is a very nice collector piece - elegantly detailed mommy bird and her 3 babies in a nest pin. 24 mm of 14 kt gold over a sterling silver base. Tiny pave set emeralds - rubies and amethyst. There are also a few clear stones - I'm guessing at white sapphire or zircons - surely not diamonds. This one measures 2 inches wide. Has a secure regular bar pin clasp. It comes from my personal collection - never worn in mint condition. I acquired this one at the Tucson Gem show many years ago - condition mint.
