How to choose jewelry someone will actually wear
Use what they already wear to choose the metal color, size, and shape.
Start with one piece they wear often
Think of the earrings or chain they put on before an ordinary day out. Notice the metal color and how much space the piece takes up. If they wear small silver studs most days, a pair in a similar size is an easier choice than a long drop they would need a different outfit for.
Check the fit before you order
For earrings, check whether they have pierced ears and which backs they prefer. If you do not know their ring size, a necklace may be easier. Compare the listed chain length with a necklace they already wear, or use a piece of string to see where that length falls.
Leave room for the occasion
If you need the gift by a particular date, check when the seller can ship it and when it should arrive. Read the return terms before adding engraving or another customization, since those options can have their own policy.
