This is an impressive piece. It’s a larger-than-usual (but wearable), dichroic glass heart with an interesting and indefinite gray/blue/green coloring, with silvery undertones, on a long suede-like cord. It’s just great!
I loved the "black pearl" necklace so why not have one in white, too? The silver work is absolutely wonderful, just like the other one. You won't regret either choice!
