Shopping for a floating diamond pendant necklace involves considering the four Cs -- color, clarity, cut and carat -- and the overall style and appearance of the setting. The cut and the diamond's size should be the most important priorities, followed by the clarity and the color.
Once the diamond itself has been selected, think about the overall style and appearance of the jewelry. The age of the wearer makes a difference, as more trendy and whimsical designs work better for younger wearers, while more elegant and refined designs work better for older wearers. Think about the thematic style of the jewelry, especially if the pendant is a gift for someone. Hearts and romantic patterns are beautiful choices for special occasions and to signify special relationships, but something more casual and attractive is better for everyday wear.
The chain length determines what clothing options work best with the jewelry. Pendants are meant to be longer, which makes them ideal for clothes that are not revealing. Shorter chains are ideal for necklines that are more exposed. When not in use, store the jewelry to prevent the metal from being damaged. When storing, avoid placing two diamonds together, as the two may scratch each other if they come in contact.
