Birthstones by Month — What They Are and What That Means for Your Jewelry

You know your birthstone. You may own jewelry featuring it. But beyond the name and the month, you don't know much about the stone — how durable it is, whether it is valuable, whether it needs special care. These things matter for decisions about wearing, insuring, repairing, or buying birthstone jewelry.

What You Need to Know

Birthstones range from diamond (the hardest mineral, ideal for daily wear) to pearl and opal (soft and porous, requiring gentle care). Understanding where your stone falls on this spectrum helps you make decisions about when to wear it, how to store it, and whether it needs special insurance considerations.

What This Information Can Tell You

Your birthstone is your birthstone. Wear it. It is special because it is yours.

Where to start

Look up your birthstone. Note its Mohs hardness. If it is below 7, it will scratch over time with daily wear — consider protective settings or occasional wear. If it is above 7, it is suitable for rings and daily wear. If it is organic (pearl, coral, amber), it needs special care — avoid water, chemicals, and ultrasonic cleaners.
