The smallest diamond you should consider is 0.25 caret weight. These will sparkle in her ears and are the least expensive diamond stud earrings. As you increase the size of a diamond, the price will go up. For instance, a 0.5 caret weight diamond will cost about double that of the smaller size. The largest diamonds typically found in stud earrings are 2.0 carets.
Next, you'll want to choose a setting. Unlike diamond rings, diamond stud earrings come mainly in two choices. The more popular is the prong style which holds the diamond in place with 4-6 prongs of a precious metal. Less popular, but more costly, is the bezel metal which completely encases the diamond.
Another factor in choosing a pair of earrings is the cut of the diamond. Oval diamonds are most common, but princess cut (square) diamonds are also popular with women.
