Birthstone Necklace | Personalized Birthstone Jewelry

Every month carries a stone. Every stone can carry a story.

The Birthstone Signature Necklace was designed as a simple, personal way to mark the month that matters to you.

Choose your own birthstone as a symbol of identity, or wear the birth month of someone whose story is intertwined with yours.

Subtle enough for every day and meaningful enough to keep for years, it is a small reminder that sometimes one detail can say more than an entire sentence.

Materials vary by design. Many ASTRA pieces are crafted from stainless steel with an 18K gold-plated finish, while selected styles may feature sterling silver components, crystals, pearls, or other materials.

Please refer to the product details and selected variant for the most accurate material information for your piece.

To help preserve the finish and appearance of your ASTRA jewelry, we recommend:

• Removing your jewelry before showering, swimming, bathing, exercising, or prolonged exposure to water.

• Avoiding direct contact with perfumes, lotions, sunscreen, household chemicals, chlorine, and salt water.

• Gently wiping your jewelry with a clean, soft, dry cloth after wear.

• Storing each piece separately in a dry place to help reduce scratching, tangling, and unnecessary friction.

Plated finishes naturally change over time depending on wear, skin chemistry, moisture, storage, and care.
