Vintage Sea Opal Sailboat Set Necklace Earrings Anzac Boxed

Lovely vintage abalone and silver tone Anzac Sea Opal sailboat figural necklace and earrings set. Pretty iridescent abalone shell boats in pierced post earrings and pendant, resting in a velveteen insert in jewelry presentation gift box. Marked Sea Opal by Anzac inside the lid, and all three pieces have tiny K hallmarks. No content marks found, and I think they are silver plated, not sterling. -- 3/4" high sailboat pendant and earrings and 16" chain. -- Beautiful near mint condition -- they look never worn -- and box shows minor expected wear and some discoloration on lid. Beautiful set!
