Magic Jewelry (also known as simply Jewelry) is an unlicensed clone of Columns for the NES programmed by Hwang Shinwei in 1990.

The graphical layout of the game was strongly inspired in New York City, and depicted the Statue of Liberty on one of the sides. Although it had only one basic mode, it proved to be fairly popular in countries where the console had a bootleg market.The following year, a sequel called Magic Jewelry II appeared in a multicart, adding a two-player mode, various options to change the jewel sets along with the layout, and a timed mode called "Flash" (unrelated to the original Flash Columns).
