Topping Heart Necklace. Unsure of which release this is, but I purchased it secondhand. Looks really great except some scratches visible in certain light.
Just as a note - this necklace looks quite silver/grayish compared to the stock photos. Not sure if it just kinda came out of the factory like this or what. I would keep it if it wasn't so silver-ish because it doesn't really match my wardrobe colors.
