I found these amazing vintage earrings with these exquisite blue stones and I fell in love. They look antique to me as you can tell by the prongs and the old rose cuts of the stones.
The patina was too worn and faded so I sent them to be plated in 14K Gold and they look awesome.
I love the color of the stones, they remind me of a rich London Blue Topaz
