An object that's been decorated with precious stones is called bejeweled. A fancy necklace or a sparkly brooch could be an example of something bejeweled.
You might hear people use this word when describing high-end decorations, like a luxurious hotel room filled with bejeweled chandeliers and ornate mirrors. Some designers specialize in creating bejeweled pieces for fashion shows or exhibitions. Even in gaming, the popular puzzle game Bejeweled challenges players to swap gems on a grid, so they're matching bejeweled patterns. The word is often used to emphasize something's value or extravagance – like saying someone was dressed up in their finest, bejeweled evening gown.
