One thing you'll want to keep in mind when ordering a heart, is which way you'd like the hole to run. Think about how you'll be using it - either as a pendant, or hanging directly from a chain, etc. Also, where the hole lies will change
the look of the heart completely. If the hole runs vertically (which is best for pendants), the shape will be of a more traditional heart shape. If the hole runs horizontally, the heart will appear funkier, with a dramatic point at the bottom. See the pics below to
get a better idea of how the two styles differ - not just in style, but in measurement as well.
