It's gorgeous, far to lovely not to wear and the two tone are so expensive nowI'd definitely add a couple of spacers. If you like pink, the pink hearts with gold heart would add some more colour to yours.
I adore the Murano ones, I think they break up the look of the charms and the different shape looks really attractive. I fell in love with the daisy one that Rose 10 has on hers and have just purchased one. I like it so much I've ordered another, they look perfect with the two tone IMO, very neutral.
My picture's not that great, my two tone is a work in progress as I've not actually got the bracelet yet. I'll add a better picture when the other spacer arrives but have a look back to page 112 and see Rose10s.
I love your bracelet!
