Here is a brief summary of the information available from the provided sources:
The March birthstone is Aquamarine. This is confirmed by the official birthstone list, which originated with the American National Retail Jewelers Association (now Jewelers of America) in 1912. Jewelry brands, such as Kendra Scott, offer collections featuring March birthstone-inspired jewelry, often utilizing an "iridescent Light Blue Illusion stone" to represent the gem. Aquamarine is traditionally associated with a blue color. The sources also indicate that March birthstone jewelry is popular for personal wear and as gifts for occasions like weddings (e.g., bridesmaid gifts).
