I like silver and white gold, although to be honest I don't wear much of either! Rose gold is nice too, although I don't own any. My "good" jewellery is mostly silver and emerald (and Connemara marble, I like the green), my birthstone is a garnet, I think. I like celtic designs, and bright glass beads. I'm a bit allergic to nickel, bracelets and necklaces are usually fine, but earrings with nickel in them will result in (TMI warning) yellow stuff being squeezed out of my earlobes the next day (sorry)
How much precious metal can a person buy with a budget of £15...?
