If you would like to surprise your loved one, there is no need for huge purchase, involving skinning your pocket too much. Give a box of chocolates wrapped in red paper, or a single red rose, why not hand write a sweet message on a beautiful paper. Imagine a picnic over the river under an umbrella because there is a lot of rain these days...
But if you planned to buy jewellery why not to consider heart shaped studs, I make them in sterling silver, yellow or rose gold filled.
And how do you like this beautiful amethyst necklace ordered specially for someone born in February, brings the luck where you need it.
