What Is a Birthstone Calculator?

While lists vary slightly across traditions, the modern list is the most commonly used in the U.S. and many online references.
This calculator gives you practical, easy-to-read results: your birthstone, color profile, symbolic themes, and a few alternative stones often used by jewelers.

Modern vs. Traditional Birthstones
The birthstones you see in stores are usually based on modern jewelry standards. Traditional lists can differ by region and historical period. For example, June may be shown as pearl, moonstone, or alexandrite, and December can include turquoise, zircon, or tanzanite.
If you are buying a gift, modern stones are usually the safest choice. If you are creating a custom or heritage piece, traditional alternatives can add personal meaning.
Why there are multiple stones for one month
Over time, gem availability, trade routes, and market trends changed what jewelers could reliably source. Alternative birthstones helped keep jewelry accessible across different budgets and styles.

Tips for Choosing Birthstone Jewelry
1) Match lifestyle to stone hardness
For daily wear, harder stones (like diamonds and sapphires) are often more durable than softer gems (like opals or pearls).
2) Consider color tone and metal pairing
Warm stones often pair beautifully with yellow or rose gold, while cooler colors can pop in white gold or platinum settings.
3) Use alternatives for budget flexibility
If your primary birthstone is expensive, a traditional alternative can preserve meaning while keeping cost manageable.
