Water Drop Crystal Earrings typically have several distinct features:

1. Shape: The earrings are designed with a crystal or gemstone cut in the shape of a water droplet. This shape often enhances their sparkle and light reflection.

2. Material: They are usually made with high-quality crystals like Swarovski or natural gemstones. The crystals are often faceted to maximize their brilliance.

3. Setting: The crystal might be set in a variety of metals, such as sterling silver, gold, or platinum, depending on the design and brand. The setting can be simple or embellished with additional smaller stones.
