I've been slowly collecting vintage coral pieces around the house for years but recently was able to buy a ton of tiny mushroom coral that was perfect for jewelry.
I ordered some silver plated adjustable rings and silver plated pendants and fell in looooove with the finished product.
These are available for sale at Shop Vintage Farmhouse
Here is some of my personal collection on the mantel. I think the piece in the silver pedestal stand is my favorite!
