Birthstone lookup
Pick a month to see its traditional and modern birthstone, alternate stones, birth flowers, color, and the zodiac date ranges that fall inside the month.
Birthstone lists are usually traced to the twelve stones named in the Aaronic breastplate in Exodus, but the month-by-month custom used today is much later. Older lists varied by region, language, and religious tradition, so a single month can have a traditional stone, a modern jewelry-trade stone, and extra alternatives that are still commonly printed in charts.
The modern U.S. list was standardized in 1912 by the American National Retail Jewelers Association, now commonly discussed through Jewelers of America and AGTA history. Later updates added or promoted stones where supply, price, durability, or consumer familiarity made the old choice hard to use. That is why June can show pearl, alexandrite, and moonstone, while August and December often have several valid entries.
This tool keeps the fields separate: traditional stone, modern stone, alternate stones, birth flower, alternate flower, color, and zodiac signs. The stone citations point to GIA and the American Gem Society, while flower entries use Society of American Florists material and a month-by-month flower chart for alternates.
