heart shaped 3.5 carat aquamarine and diamond ring in 18K white gold
8mmx6mm oval cut blue topaz in 18K yellow gold
1.37 carat sapphire with a halo of micro pave diamonds set in 18k white gold"Something old, something new, something borrowed, something blue, and a sixpence in your shoe" is one of my favourite wedding traditions. I love the idea of being mindful of something old from your life before marriage, welcoming the new, borrowing the luck from a happily married woman you love, and carrying something blue (to remind yourself of being virtuous. ha! we all know what THAT one means!)
And a sixpence in your shoe: excellent if you need to stop and make a call in a Dickensian phone booth? But seriously, a symbol of monetary fortune is not a bad thing to start out your marriage with.
