    Note: Plain metal bands offered by Ada are not custom cast and are available as off-the-shelf items for expediency and cost. As a result, this band may have very slight differences in color for yellow and rose gold from custom cast pieces. If you are interested in a custom cast band to accompany your engagement ring, please inquire.
